▼ This study aimed at assessing physio-chemical parameters, nutrients, fluoride, pesticides and selected heavy metals contamination in Lake Elementaita drainage basin. Water pollution has been identified globally as one of the most serious problems in environmental conservation. Pesticides, heavy metals and nutrients are of concern in the world waters and have been considered as long-term worldwide water pollutants since they cause deterioration of water quality and cause adverse effects on the lake ecosystem. Water, sediments and soil were collected from seven sites within Lake Elementaita drainage basin and analysed for physico-chemical parameters, nutrients, fluoride, heavy metals and organochlorine pesticides (OCP) residues. The sampling strategy covered dry (October 2014) and wet (April 2015) season. Analysis of the 17 OCPs was done using gas chromatograph equipped with electron capture detector (GC-ECD), whereas for heavy metals analysis atomic absorption spectrometer was used. Physico-chemical parameters analysed included electrical conductivity, pH, TDS, TSS and temperature. Nitrate and phosphate concentrations were below WHO maximum limits with dry season recording higher values. Phosphates concentrations ranged from 0.02±0.00 to 0.38±0.07 mg/L, 0.45±0.02 to 10.04±0.10 mg/kg and 0.78±0.00 to 4.47±0.03 mg/Kg in water, sediment and soil, respectively. Nitrates ranged from 0.43±0.04 to 3.00±0.36 mg/L, 0.36±0.06 to 2.21.02±0.18 mg/kg and 0.65±0.05 to 4.90±0.29 mg/kg in water, sediment and soil, respectively. All the 17 OCPs were detected with concentrations below WHO maximum limits. The OCPS residues ranged from BDL to 0.49±0.09 μg/L, BDL to 762.27±91.70 μg/kg and BDL to 615.93±119.21 μg/kg in water, sediment and soil samples, respectively in dry season and BDL to vi 0.16±0.00 μg/l, BDL to 42.97±1.00 μg/kg and BDL to 13.92±0.21 μg/kg in water, sediment and soil samples, respectively in wet season. Endosulphan sulphate recorded high concentration in soil and sediment samples in both seasons. Concentrations of cadmium, copper, zinc and lead were above WHO maximum limits for water in some samples analysed with the wet season recording high values. Cadmium values ranged between 0.04±0.00 and 0.35±0.02 mg/L, 2.06±0.42 and 16.07±0.02 mg/kg, 2.78±0.08 and 29.75±0.14 mg/kg in water, sediment and soil, respectively. Copper concentrations ranged between 0.07±0.04 and 8.49±0.40 mg/L, 2.93±0.66 and 861.76±80.58 mg/kg, 2.96±0.39 and 865.83±5.76 mg/kg in water, sediment and soil, respectively. Lead concentrations ranged between BDL to 9.28±0.9 mg/L, BDL to 475.75±16.61mg/kg, 10.38±0.99 and 502.18±20.76 mg/kg in water, sediment and soil, respectively. Zinc concentration ranged between 0.14±0.00 and 0.41±0.02 mg/L, 45.73±9.44 and 106.28±2.89 mg/kg, 57.95±6.68 and 86.95±5.55 mg/kg in water, sediment and soil, respectively. Fluoride concentration in water ranged between 1.70±0.28 to 977.80±0.01 mg/L in Mbaruk River and Lake Elementaita North, respectively. The results revealed high levels of heavy metals in water, soil and…

▼ Gully erosion and headcut migration has been at the crux of wetland degradation in South Africa. The resulting erosion and draining effect has seen more than 50% of wetlands in the country degraded. This study investigated the degradation of indigenous Palmiet, peat forming, wetlands through headcut erosion. This was done by exploring the relationship between headcut migration rate and morphodynamic characteristics through the use of multiple regression analysis. Wetlands investigated in this study occurred in the Kromme River catchment and Nuwejaars River catchment, in the Eastern Cape and Western Cape respectively. Morphodynamic characteristics assessed include headcut dimensions, gully characteristics, soil characteristics and drainage basin characteristics. These parameters were determined either through infield assessment, image analysis or laboratory analysis. Three headcut migration rate types were calculated through a combination of infield measurements and image analysis techniques executed within ArcGIS. These migration rate types include apex advancement (m/a), gully expansion (m2/a) and volume erosion (m3/a). Statistical analysis revealed significant relationships between morphodynamic characteristics and both volume erosion and gully expansion. Morphodynamic characteristics such as drop height, apex width, gully width, drainage rate and sand content were found to have a direct relationship with migration rates, whereas characteristics such as average drainage basin slope, clay content, silt content, SOM content and soil saturation were found to have an indirect relationship with headcut migration rates. Results provide insight into the headcut migration process, its influencing factors and the potential for headcut migration rate prediction. An evaluation of these results using WET-Health found that the wetland management tool captures wetland geomorphic controls to an accuracy of 68% and 70%. Furthermore, the influence of morphodynamic characteristics on migration rates contributes to the wetland rehabilitation process as it allows for the identification of headcut sites most susceptible to erosion. This will then allow for timely wetland rehabilitation, decreasing the rate of net wetland degradation and improving the management and efficiency of wetland restoration.

Esta pesquisa consistiu na análise geomorfológica e em um conjunto de levantamentos dos aspectos físicos da bacia hidrográfica do Ribeirão Balainho. O trabalho baseou-se no mapeamento morfométrico e morfográfico, além de observações de campo para o levantamento das características morfológicas da referida bacia. Os dados coletados visaram também estabelecer as características morfoestruturais e morfoesculturais, a fim de indicar áreas com maior potencialidade a processos denudativos. Para tal, optou-se pela utilização de cartografia geomorfológica de detalhe (1: 25.000) por meio da fotointerpretação de fotografias aéreas e de técnicas de mapeamento (morfografia) apresentadas por Tricart (1965) e Verstappen e Zuidam (1975). Quanto às técnicas na confecção das cartas morfométricas, estas se basearam nos apontamentos de Spiridonov (1981), Cunha, Mendes e Sanches (2003). As modificações morfológicas observadas, sobretudo os processos lineares de erosão foram associados a causas distintas em cada setor compartimentado da bacia (alta, média e baixa bacia), devido a características geológicas, morfológicas, pedológicas, de cobertura superficial e de usos distintos do solo.

This research is consisted of a set of data about the physical aspects of the Ribeirão Balainhos drainage basin. The study is based on morphometric and morphografic mapping and on field observations for the attainment of morphological characterization of the drainage basin. The data collected aimed to determine the morphostructural and morphosculpture characteristics, with the goal of point the areas with higher risks to suffer denudation process. For this, it was chosen the detailed geomorphological cartography (1:25.000), by the photointerpretation of aerial photographs and mapping technics (morphography), given by Tricart (1965) and Verstappen and Zuidam (1975). By the technics used in creation of the morphometrics charts, they were based on Spirodonov (1981), Cunha, Mendes and Sanches (2003) notes. The morphological changes viewed, especially the linear erosions processes, were associated to different reasons in each sector compartmented of the basin (upper, middle and lower), due the geological, morphological, pedological, surface coverage soil and land uses characteristics.

▼ ENGLISH ABSTRACT: In recent years acid mine drainage (AMD) has become the focus on many mine sites throughout the world. The Witwatersrand gold mines have been the main focus of AMD in South Africa due to their extensive impact on especially groundwater resources. The Witwatersrand Basin is a regional geological feature containing the world-famous auriferous conglomerate horizons. It is divided into sub-basins and the East Rand Basin is one of them. Due to the regional scale of the East Rand Basin AMD issues, a systems approach is required to provide a useful tool to understand the pollution source term and fate and transport dynamics and to aid in environmental decision making and to evaluate the geochemical impact of mitigation measures and evaluate future scenarios. The numeric geochemical models, using a systems perspective, show that the mine waste facilities, specifically the tailings dams are significant contamination point sources in the East Rand Basin, specifically for acidity (low pH), SO4, Fe, Mn, U, Ni, Co, Al and Zn. When the AMD solution enters the soil beneath the tailings, ferrous and SO4 concentrations remain elevated, while Mn, U, Ni and Co and perhaps other metals are adsorbed. After ~50 years the pollution plume starts to break through the base of the soil profile and the concentration of the adsorbed metals increase in the discharging solution as the adsorption capacity of the soil becomes saturated. The pollution pulse then starts to migrate to the shallow groundwater where contamination of this resource occurs. Toe seepage from the tailings either first reacts with carbonate, where acidity is neutralised to a degree and some metals precipitated from solution, where after it reaches the surface water drainage, such as the Blesbokspruit, where it is diluted. Some evaporation can occur, but evaporation only leads to concentration of acidity and dissolved constituents, thereby effectively worsening the AMD solution quality. The mixing models have shown that the dilution factor is sufficient to mitigate much of the AMD, although seasonal variability in precipitation and evapotranspiration is expected to have some influence on the mixing ratio and some variability in the initial solution will also be reflected in variation in surface water quality. From a sustainability perspective, a basic cost benefit analysis shows that the costs for the operating mine and society in general is lower when mitigation measures are employed during operation. For a theoretical mine in the ERB with an operating life of 100 years, the cost of operational mitigation measures is ~R 31 billion. This value is 4% of turnover and 19% of profits over the time period. Post closure remediation costs are ~R 67 billion. This value is 8% of turnover and 41% of profit over the time period. Although the initial capital investment in mitigation measures is substantial, although some measures will be implemented during operation, it is a smaller percentage of profits than eventual post-closure… Advisors/Committee Members: Roychoudhury, Alakendra, Stellenbosch University.

▼ It is recognised that some proportion of South American large-scale topography has been generated by convection within the Earth's mantle. Yet, spatial and temporal patterns of dynamic topography remain poorly understood. Variation of present-day dynamic topography can be mapped in the oceans by calculating residual depths with respect to the well-known age-depth relationship. Along the margins abutting South America, anomalies with amplitudes of ±1 km and wavelengths of ∼10³ km are observed. Onshore, dynamic topography is investigated by analysing a range of disparate datasets. Positive long-wavelength free-air gravity anomalies and slow shear-wave mantle velocities correlate with high plateaux of the Borborema Province and the Central Andean Altiplano. Admittance analyses of these regions are used to gauge dynamic support. Admittance of >20 mGal km^-1 at wavelengths > 500 km suggests partial dynamic support. In this context, inverse modelling of longitudinal river profiles is applied to retrieve a continental-scale uplift history. Erosional parameters are calibrated against an independently derived uplift history of the Borborema Province that reveals uplift in the last 30 Ma. Results suggest that the bulk of South American regional topography grew during Cenozoic times. In the Central Andean Altiplano and Southern Patagonia, most uplift occurred in the last 20 Ma. In both areas, widespread Cenozoic magmatism suggests that youthful uplift might be related to asthenospheric upwelling. Uplift histories are used to predict sediment flux to the Amazon Fan, which reveals that onset of the delta is a direct consequence of intensified Andean uplift. Analysis of the Parna\'iba cratonic basin of northeast Brazil is carried out to evaluate long-term evolution of vertical motions and to understand the mechanisms driving this basin's subsidence. Joint interpretation of a deep seismic reflection profile that traverses the basin and receiver function analyses reveal a 3 km thick basin underlain by three crustal blocks. Moho depths of 38 – 43 km are observed beneath the Amazon craton west of the basin, whereas depths of 35 km are found underneath the Borborema Province to the east. The Moho is located at 38 – 42 km depth beneath the basin. Stratigraphic architecture from shallow seismic reflection profiles reveals undisturbed deposition between Palaeozoic and Mesozoic times. Rift-type structures are locally imaged. Subsidence analysis reveals thermally-driven subsidence with thermal time constants of ∼ 70 – 80 Ma. Assessment of crustal thickness variations indicates that minimal extension of up to 80 km, with small stretching factors (up to 1.15), is plausible beneath Parna\'iba. One- and two-dimensional strain rate histories suggest that pre-Silurian rifting followed by thermal subsidence is possible if a minimum of 1 km of syn-rift deposition occurred. Basin-wide erosional unconformities are observed throughout the sedimentary section and correlate with departures from long-term subsidence trends. These…

A caracterização hidrogeoquímica da bacia do rio Sorocaba foi realizada a partir do estudo detalhado das cargas fluviais particulada e dissolvida, considerando a dinâmica dos transportes das principais espécies químicas, bem como os aportes atmosféricos e antrópicos, identificando os processos erosivos mecânicos e químicos predominantes na bacia de drenagem. A caracterização hidrológica permitiu identificar os principais mecanismos de recarga e descarga na bacia de drenagem e determinar o escoamento superficial rápido, revelando os períodos de maior potencial erosivo nos últimos 20 anos. O estudo da dinâmica da carga fluvial particulada mostrou a ocorrência de processos de remobilização e sedimentação ao longo da bacia, permitindo verificar um aumento do transporte fluvial específico em 2,5 vezes das nascentes até a foz. A erosão mecânica, calculada com base no transporte de sedimentos finos em suspensão junto à foz do rio Sorocaba, foi de 55,70 t km-2 a-1, indicando uma taxa de degradação física de 37,88 m Ma-1. A origem da matéria orgânica na carga particulada fluvial se mostrou associada aos efluentes domésticos após caracterização isotópica do 13C. O comportamento hidroquímico fluvial evidenciou uma diferença de predomínio de espécies químicas dissolvidas entre as cinco estações de amostragem, permitindo verificar a influência dos processos de diluição fluvial, de acordo com as relações concentração x vazão. O modelo geoquímico utilizado permitiu estimar o CO2 atmosférico/solo consumido durante o processo de alteração de rochas na bacia de drenagem em 198 x 103 moles km-2 a-1, dos quais 98% foi relacionado à alteração de silicatos. O modelo de reconstituição desse consumo nos últimos 59 anos mostrou-se pouco variável, entretanto o modelo associado exclusivamente aos silicatos indicou um aumento no mesmo período, a uma taxa de 2,7 x103 moles km-2 a-1. Comparada com a erosão mecânica, a erosão química se mostrou inferior em cerca de 2,5 vezes, enquanto que, ainda em termos de erosão química, as taxas de alteração de silicatos e carbonatos na bacia de drenagem foram de 9,4 e 5,3 m Ma-1, respectivamente. O índice de alteração de rocha RE, determinado a partir dos dados geoquímicos das águas fluviais, indicou a mudança de um possível domínio de estabilidade da caulinita para o das argilas 2:1, evidenciando a ocorrência do processo de bisialitização

The hydrogeochemical characterization of the Sorocaba River basin was performed from the detailed study of particulate and dissolved river loads. Considering the main chemical species transported, as well as the atmospheric and anthropogenic inputs, it ws identified the mechanical and chemical erosion processes prevailing in the drainage basin. The hydrologic characterization identified the main mechanisms of recharge and discharge in the drainage basin, and allowed to determine the quickly surface runoff, showing periods of increased erosion potential in the last 20 years. The study of the particulate load dynamics demonstrated the occurrence of sedimentation and…

▼ It is recognised that some proportion of South American large-scale topography has been generated by convection within the Earth's mantle. Yet, spatial and temporal patterns of dynamic topography remain poorly understood. Variation of present-day dynamic topography can be mapped in the oceans by calculating residual depths with respect to the well-known age-depth relationship. Along the margins abutting South America, anomalies with amplitudes of ±1 km and wavelengths of ∼10³ km are observed. Onshore, dynamic topography is investigated by analysing a range of disparate datasets. Positive long-wavelength free-air gravity anomalies and slow shear-wave mantle velocities correlate with high plateaux of the Borborema Province and the Central Andean Altiplano. Admittance analyses of these regions are used to gauge dynamic support. Admittance of > 20 mGal km^-1 at wavelengths > 500 km suggests partial dynamic support. In this context, inverse modelling of longitudinal river profiles is applied to retrieve a continental-scale uplift history. Erosional parameters are calibrated against an independently derived uplift history of the Borborema Province that reveals uplift in the last 30 Ma. Results suggest that the bulk of South American regional topography grew during Cenozoic times. In the Central Andean Altiplano and Southern Patagonia, most uplift occurred in the last 20 Ma. In both areas, widespread Cenozoic magmatism suggests that youthful uplift might be related to asthenospheric upwelling. Uplift histories are used to predict sediment flux to the Amazon Fan, which reveals that onset of the delta is a direct consequence of intensified Andean uplift. Analysis of the Parna\'iba cratonic basin of northeast Brazil is carried out to evaluate long-term evolution of vertical motions and to understand the mechanisms driving this basin's subsidence.

▼ The increasing global air temperature will trigger changes in the global mean water vapor, precipitation patterns and evapotranspiration, which further leads to changes, for instance, instream flow, groundwater flow and soil moisture. Projections of future changes in thehydrological regime of the Aral Sea Drainage Basin (ASDB) in Central Asia are however highlyuncertain, due to complexities of natural and engineered water systems of the basin. The AmuDarya River Delta (ADRD) is vital to the water budget of the Large Aral Sea, the livelihood inUzbekistan and Turkmenistan, as well as the surrounding riparian ecosystem. This study attemptsto investigate responses of river flow in the Aral Sea Drainage Basin and key riparian vegetationspecies (of the so-called Tugai community) in the Amu Darya River Delta to projected futureclimate change. Results from hydrological model and outputs from multi-GCM predictions providea basis for conducting more robust quantitative analysis of possible future hydro-climatic changesin the Amu Darya River Basin. A qualitative synthesis of the suitability of Tugai is furthermoreperformed in order to increase the knowledge of the riparian vegetation status under thechanging hydro-climatic conditions. The results show that the averaged temperature in the ASDBis likely to continuously increase and yield a total increase of about 2 °C ~ 5°C by 2100. Thechange trend of the annual regional precipitation of 2100 is relatively unclear, with estimatesranging from 50 mm lower than today to 75 mm higher than today. Modeled ensemble means (EM)river flow, obtained from hydrological modeling of climate output from multi-GCM projections,converge on showing future decreases in river runoff (R). Projected absolute R may decrease tozero around 2100, implying no surface flow and a dry out near the river outlet. The relationship ofwater flux between upstream and downstream will be changed dramatically due to climatechange. More specifically, R of the upstream region will decrease, and it is likely to becomeinsufficient for feeding downstream river reaches as it used to. The decreased river flow in thedelta may accelerate the desertification and salinization processes. Consequently, speciestransitions may occur, along with degradations of the existing Tugai communities. Theuncertainties of hydro-climatic change projections to some extent hinder the understanding of thedynamic hydrological-climatic-ecological system. However, the detailed responses of the delta toclimate change based on multiple qualitative and quantitative analyses provide an important basisfor the formulation of more robust forecasts on the future ecological development in the ADRD, and further for recommendations of measures to mitigate the ecosystem’s deterioration under achanging climate.

Lors de la phase précoce de l’orogène pyrénéen, la localisation et le calendrier de la mise en place des premiers reliefs pyrénéens restent incertains. L’enregistrement des dépôts continentaux du Crétacé terminal au Paléocène dans les bassins péri-orogéniques du système pyrénéen oriental permet d’observer les architectures fluviatiles pour (1) reconstruire les paléo-drainages, (2) estimer les localisations des paléo-reliefs, et (3) contraindre et comparer les flux sédimentaires dans le système. L’étude a été menée dans le Bassin de Tremp (Espagne), dans les Corbières, en Languedoc et en Provence (France). La première partie de ce travail correspond à l’analyse sédimentologique et la cartographie des objets permettant de réaliser des modèles de dépôts et d‘estimer la provenance des sédiments. La deuxième partie de ce travail consiste à améliorer le calage stratigraphique de ces séries continentales grâce à une analyse des variations du δ13Corg réalisée sur deux coupes de part et d’autre des Pyrénées Orientales (Orcau-Talarn, en Espagne et Saint-Ser en Provence) du Campanien au Danien, en comparant le signal à des coupes de références marines. Ce travail a permis de montrer que du Campanien au Maastrichtien inférieur, les flux majeurs sont enregistrés dans la zone sud des Corbières et dans le bassin de Tremp ; au Maastrichtien supérieur, des flux locaux émanent de petits reliefs actifs ; à la transition Crétacé-Tertiaire, l’ensemble de la zone enregistre une période lacustre plus importante dans le domaine nord ; au Dano-Sélandien, le système enregistre un flux majeur au nord du Bassin de Tremp et dans l’ ouest des Corbières, tandis que les petits reliefs actifs forment encore des sources locales dans toutes la zone septentrionale. Ainsi les paléo-drainages montrent que la majorité des sédiments proviennent en début d’orogenèse d’abord des zones externes, et d’une zone proto-axial orientale, disparue lors de l’ouverture du Golfe du Lion, puis la ré-activation d’anciennes structures au Nord et l’émersion des nappes au Sud engendrent la production locale de sédiments et le partitionnement des flux. Il faut attendre le Thanétien moyen voire l’Eocène pour enregistrer des sédiments de la zone axiale, soit environ 26 Ma après le début de la convergence.

During the Pyrenean early orogenic phase of the Pyrenees, the location of the first Pyrenean reliefs and the timing of their establish development remain uncertain. The records of continental deposits from Late Cretaceous to Palaeocene in the peri-orogenic basins of the eastern Pyrenean system allows the definition of various fluvial architectures that lead to (1) reconstruct paleo-drainages, (2) estimate paleo-relief locations, and (3) constrain and compare sediment fluxes in the system. The study was conducted in the Tremp Basin (Spain), and in Corbières, in Languedoc and in Provence (France). The first part of this work corresponds to the sedimentological analysis and fluvial object mapping allowing the characterisation of depositional models and the estimation of…

A atualidade Ã marcada por uma forte exploraÃÃo aos recursos naturais sendo que o resultado da sobre-exploraÃÃo Ã refletido imediatamente na paisagem. Os ambientes aquÃticos sÃo um dos sistemas que rapidamente respondem as modificaÃÃes instauradas sobre o seu meio, dessa forma, as bacias hidrogrÃficas apresentam-se como Ãreas excelentes para estudos de diagnÃstico, pois podem indicar transformaÃÃes ocorridas em escala espacial e temporal como foi realizado por Gorayeb (2008) e Lima (2012). Foi nesse sentido que se desenvolveu um estudo na bacia de drenagem do aÃude Forquilha, localizada no setor noroeste do estado do CearÃ, regiÃo semiÃrida do estado entre as coordenadas 40Â06â51ââ de longitude oeste e 3Â45â39ââ de latitude sul. A bacia de drenagem do aÃude Forquilha abrange uma Ãrea de 191,83 Km2 e estÃ inserida dentro do municÃpio Forquilha, no distrito de mesmo nome, distante 220 km de Fortaleza. AlÃm do aÃude Forquilha existem na Ãrea outros reservatÃrios de pequeno porte como o aÃude Pocinhos e o Juazeiro. O trabalho teve como objetivo a efetivaÃÃo de uma anÃlise geoecolÃgica, baseada no estudo das paisagens, visando Ã obtenÃÃo de um diagnÃstico do estado dos recursos naturais. Metodologicamente, utilizou-se da Geoecologia das Paisagens que visa Ã investigaÃÃo do meio natural atravÃs de um enfoque sistÃmico, desta forma, fundamentando-se principalmente nos trabalhos de Rodriguez; Silva; Cavalcanti (2004); Rodriguez, Silva (2002) e Rodriguez, Silva, Leal (2011). Para isso, realizou-se um levantamento bibliogrÃfico e cartogrÃfico; elaboraram-se mapas temÃticos da bacia na escala de 1:80000 atravÃs das tÃcnicas de geoprocessamento com apoio de produtos cartogrÃficos como a Folha SA.24-X-D-IV Sobral na escala de 1:100.000 (1972) alÃm de imagens de satÃlite Landsat 5 e 8 (2009/2014) que tambÃm serviram como suporte as prÃticas de campo. Com a efetivaÃÃo da anÃlise paisagÃstica, obteve-se a caracterizaÃÃo e a classificaÃÃo da paisagem identificando cinco unidades na bacia onde se apontou suas potencialidades e limitaÃÃes. Com o diagnÃstico, pode-se afirmar que a paisagem da bacia do aÃude Forquilha encontra-se descaracterizada de seus aspectos naturais com processos acelerados de degradaÃÃo, pois identificaram-se diversos impactos negativos na Ãrea como o desmatamento, a degradaÃÃo dos solos e a poluiÃÃo do aÃude Forquilha que apresentou eutrofizaÃÃo na maior parte do ano de acordo com as anÃlises realizadas. Por fim, constatou-se que o uso e ocupaÃÃo do solo na Ãrea vÃm sendo realizado de forma irregular o que indica a necessidade de se propor aÃÃes educativas junto Ã populaÃÃo e aos ÃrgÃos administrativos responsÃveis pela gestÃo da bacia a fim de viabilizar o uso sustentÃvel dos recursos naturais.

Nowadays has been marked by a strong exploration for natural resources and the result of overexploitation is reflected immediately in the landscape. The aquatic environments are one of the systems that respond quickly to changes brought about it thus the hidrografic basins are presented as excellent areas for studies…

O presente trabalho tem o propósito de investigar as interações socioambientais que se materializam na Bacia do Rio Catolé Bahia, considerando os processos históricos de apropriação do território e uso dos recursos naturais, e as sucessivas paisagens que dão suporte à configuração atual dos fenômenos geográficos. Utiliza-se a concepção sistêmica como base de análise dos fenômenos e avalia-se o cenário atual das derivações antropogênicas, pautado em critérios quantitativos e qualitativos. A análise morfométrica da bacia, juntamente com a leitura da organização das paisagens e das relações conflituosas entre os usuários da água e da terra, é critério fundame ntal para a compreensão do cenário geográfico atual. Procede-se a uma análise da inserção da Bacia do Rio Catolé como uma componente sistêmica dos mecanismos globais e regionais em que ela está inserida, considerando as complexas e dinâmicas relações que comandam os fluxos de matéria e energia. Os levantamentos das características do meio físico, os trabalhos de mapeamento, as atividades de campo confrontando os elementos do quadro natural e o uso dos recursos naturais e suas derivações, como também os diálogos com produtores rurais, gestores ambientais e demais agentes envolvidos no uso e na gestão territorial foram os caminhos metodológicos que possibilitaram a identificação das questões nodais quanto à gestão territorial, pautada nos princípios do uso dos recursos naturais com a manutenção da qualidade ambiental. Como resultados da pesquisa, são apresentados os retrospectos históricos das atividades produtivas sobre os recursos ambientais e discutidos as interações socioambientais e seus reflexos em três grandes unidades de paisagem, de forma a levantar elementos que contribuam para o ordenamento territorial. A área enfrenta fortes discrepâncias entre o uso atual dos recursos naturais e o seu potencial. Conclui-se que a retomada do equilíbrio socioambiental na Bacia do Rio Catolé poderá ser alcançada com ações conjuntas dos usuários da água e do solo, órgãos das esferas municipal, estadual e federal e participação do meio técnico-científico. Para tanto, a implantação do Plano Diretor e do Comitê de Bacia, associada à criação de um Fundo de revitalização da Bacia do Rio Catolé, apresenta-se como instrumentos possivelmente eficazes.

The present work aims to investigate the socio-environmental interactions which materialize in the Basin of the Catole River Bahia, considering the historical processes of appropriation of territory and use of the natural recourses, and the successive landscapes which support the current configuration of geographical phenomena. It is used the systemic conception as the basis of analysis of the phenomena, and it is evaluated the current scenery of anthropogenic derivations, based on quantitative and qualitative criteria. The morphometric analysis of the basin, together with the reading of organization of the landscapes and conflicting relations between the users of water and land, is fundamental criterion for understanding the…

A relação do homem com o ambiente, inicialmente, ocorre de forma natural. Passado algum tempo, há um acelerado crescimento populacional e surgem novas tecnologias, que intensificam as atividades antrópicas tanto no ambiente terrestre quanto no aquático, impondo assim, desequilíbrio na relação homem-natureza. Desse modo, quantitativa e qualitativamente, a água no planeta encontra-se em risco devido à poluição. Por isso, a conservação dos recursos hídricos é uma preocupação crescente dos órgãos públicos e privados. Estudos e pesquisas voltados à integração dos ecossistemas terrestre e aquático vêm se destacando, visando à proteção e preservação do ambiente. Dessa maneira, objetivando uma abordagem integrada dos ecossistemas terrestre e aquático, na dinâmica da qualidade ambiental, este trabalho identificou a relação entre as características limnológicas do Reservatório Rodolfo Costa e Silva - RS, com o ecossistema terrestre, de acordo com o uso da terra e as características físicas da área de captação do Reservatório. Criou-se um banco de dados geográficos no aplicativo SPRING, que, utilizando cartas topográficas, imagens dos Satélites CBERS-2 CCD e do LANDSAT-5 TM e dados de GPS, foram elaborados os mapas temáticos de declividade, de uso da terra, de áreas de preservação permanente (APP) e de conflitos ambientais. Do resultado da análise desses dados, identificou-se que, quanto ao uso da terra na área de captação do Reservatório, predominaram dentro dos ciclos agrícolas, respectivamente, a agricultura, o campo e a floresta. Em relação às APP localizadas na faixa marginal das drenagens e no entorno das nascentes e do próprio Reservatório, à luz da legislação ambiental federal vigente, identificou-se que o local apresenta mais de 72% das APP com conflitos ambientais. A respeito das classes de declividade do relevo, a área de estudo é representada na maioria por formas plana a fracamente ondulada. Quanto à avaliação das características limnológicas do Reservatório, as diferenças mais expressivas ocorreram nas variáveis total de sólidos em suspensão (TSS), transparência da água e potencial Hidrogeniônico (pH). Portanto, pode-se inferir que as maiores alterações apresentadas pelas variáveis limnológicas no período de 20/10/2005 a 26/09/2006 estão vinculadas, de maneira geral, à primeira (20/10/2005), segunda (18/11/2005), quarta (06/01/2006), sétima (25/03/2006) e décima terceira (26/09/2006) coletas de campo, associadas com o uso da terra destinado às classes agricultura (especialmente solo exposto) e campo; e à influência dos maiores índices pluviométricos ocorridos a 26 e 7 dias anteriores à realização das coletas de campo. As diferenças nos tipos de uso da terra proporcionaram compartimentos limnológicos distintos, o que aponta a influência do ecossistema terrestre sobre o aquático no Reservatório.

"Jason's Creek" is a stream draining 2.2 km² of arctic limestone terrain. Its annual regime consists of a ten-month period in which it is frozen to its bed, a short spring flood which occurs shortly after tenperatures cross the freezing-point in late June, and a period of about two months during which discharge is relatively low and fluctuates diurnally in response to inputs of radiative and heat energy to the snowpack. In 1970, the spring flood occupied the first two weeks of July and effected the discharge of some nine-tenths of total annual runoff. Tne low flow period was punctuated by rainstorms which generated sharply-defined floods: basin response was rapid and efficient, for storm runoff is facilitated over the unvegetated ground and through the shallow active layer above the permafrost table. Covariance and spectral analyses suggest a basin lag time of five hours, both for low discharges of snowmelt water and flood discharge of rainwater. It appears, from the spectra of the time series, that radiation is a better index of snowmelt discharge than is temperature. Most of the annual removal of sediment from the basin takes place during the spring flood, when the stream is turbid and movement of channel bed material is vigorous, In the longer period after the flood the main component of stream load is the solute load. The concentration of dissolved material varies inversely while suspended sediment concentration varies directly with discharge. Solute concentrations are lower than those commonly found in limestone streams at lower latitudes, suggesting that in "Jason's Creek" the increased solubility of CO2 at low temperatures is more than counteracted by a decrease in the rate of solution of CaCO3. There are also indications that the concentration of CO2 in snowmelt water 2 may be smaller, in absolute terms, than in rainwater. The role of water is crucial in many processes acting on slopes and delivering detritus to stream channels; rills, for example, remove ions in solution and fine particles in suspension, notably from the base of talus slopes, and lubrication of the active layer after rainstorms generates bowl-slide and mudflow activity.

▼ This thesis investigates the development of regional drainage patterns within intra-continental rift basins using remote sensing data, field studies and numerical models. By examining modern-day extensional settings, such as the Basin and Range, USA, and the East African Rift System (EARS), this study elucidates the controls upon regional source-to-sink systems and assesses the findings in relation to existing, conceptual tectono-stratigraphic and drainage models. Rift basins are generally well studied and facies models well established. However, there is a tendency to overlook the regional perspective. Many drainage evolution studies and tectono-stratigraphic models focus upon the development of individual basin-bounding faults and half-grabens, often overlooking the influence of regional-scale drainage evolution upon landscape and stratigraphic development. On a regional scale, extensional basins are segmented into numerous sub-basins, which: (i) exist at different elevations; (ii) subside at different rates; (iii) vary in their degree of fluvial connectivity; and, (iv) may experience significant shifts between erosional and depositional regimes as drainage networks evolve. Through observations of the Basin and Range, and three-dimensional numerical modelling, it is shown how sub-basins with identical tectonic and climatic boundary conditions can exhibit vastly different stratigraphic fills depending on the degree of fluvial connectivity and their relationship to adjacent sub-basins. In addition, drainage integration is recognised as an overlooked, yet important process in the source-to-sink evolution of rift basins. Drainage integration between sub-basins of varying elevations is shown to cause widespread erosion and sediment bypass in the upstream basin, while contemporaneously increasing sediment supply to the downstream basin. A case study of the Tecopa Basin shows drainage integration as a powerful driver of base level fall and landscape transience in the absence of significant tectonic or eustatic controls. The differential gradients created by base level fall cause further upstream drainage rearrangements.To understand the evolution of regional hinterland drainages, two rift segments of varying maturity are compared. The Okavango Rift Zone represents a rift initiation phase segment while the Albertine Rift represents a rift climax phase segment. Through analysis of the contributing drainage patterns a model is proposed where early rift drainage is dominated by antecedent directions, with large, low relief, low slope catchments. As rifts mature catchments increase in relief and slope but reduce in asymmetry as the influence of antecedent drainage direction is reduced via tectonic tilting, drainage reversals and ponding.The thesis concludes that current tectono-stratigraphic models of sub-aerial rift settings commonly overlook the role of inter-basin erosion, under-appreciate the influence of antecedent drainage direction in hinterland input, and over-emphasise the role of axial rivers.

Rift basins are generally well studied and facies models well established. However, there is a tendency to overlook the regional perspective. Many drainage evolution studies and tectono-stratigraphic models focus upon the development of individual basin-bounding faults and half-grabens, often overlooking the influence of regional-scale drainage evolution upon landscape and stratigraphic development. On a regional scale, extensional basins are segmented into numerous sub-basins, which: (i) exist at different elevations; (ii) subside at different rates; (iii) vary in their degree of fluvial connectivity; and, (iv) may experience significant shifts between erosional and depositional regimes as drainage networks evolve. Through observations of the Basin and Range, and three-dimensional numerical modelling, it is shown how sub-basins with identical tectonic and climatic boundary conditions can exhibit vastly different stratigraphic fills depending on the degree of fluvial connectivity and their relationship to adjacent sub-basins. In addition, drainage integration is recognised as an overlooked, yet important process in the source-to-sink evolution of rift basins. Drainage integration between sub-basins of varying elevations is shown to cause widespread erosion and sediment bypass in the upstream basin, while contemporaneously increasing sediment supply to the downstream basin. A case study of the Tecopa Basin shows drainage integration as a powerful driver of base level fall and landscape transience in the absence of significant tectonic or eustatic controls. The differential gradients created by base level fall cause further upstream drainage rearrangements. To understand the evolution of regional hinterland drainages, two rift segments of varying maturity are compared. The Okavango Rift Zone represents a rift initiation phase segment while the Albertine Rift represents a rift climax phase segment. Through analysis of the contributing drainage patterns a model is proposed where early rift drainage is dominated by antecedent directions, with large, low relief, low slope catchments. As rifts mature catchments increase in relief and slope but reduce in asymmetry as the influence of antecedent drainage direction is reduced via tectonic tilting, drainage reversals and ponding. The thesis concludes that current tectono-stratigraphic models of sub-aerial rift settings commonly overlook the role of inter-basin erosion, under-appreciate the influence of antecedent drainage direction in hinterland input, and over-emphasise the role of axial rivers.

▼ ABSTRACT SAND COMPOSITIONAL CHANGES AS A KEY FOR SEQUENCE-STRATIGRAPHIC INTERPRETATION: THE PLEISTOCENE TIBER RIVER DELTAIC SUCCESSION (ITALY) By Daniel Tentori Master of Science in Geology Sand samples collected from the Tiber River of central Italy reflect sediment input from the main tributaries and various source rock lithologies distributed across the drainage basin. Monomineralic quartz and feldspar grains, and siliciclastic sedimentary lithic fragments are supplied by Oligocene to Miocene siliciclastic units that crop out in the upstream part of the drainage basin. Carbonate lithic fragments, very common throughout the Tiber River, are supplied by Triassic to Miocene carbonate successions that crop out in the upper and middle parts of the drainage basin. Volcaniclastic rock fragments and monomineralic pyroxene and feldspathoid grains derived from lavas and pyroclastic flow deposits of the Quaternary Roman Comagmatic Province are concentrated in the lower reaches of the Tiber River, where these volcanic units crop out. The dominant components of Tiber deltaic coastal sand are monomineralic grains of quartz, and pyroxene, and carbonate lithic fragments, suggesting that there is some compositional modification by wave reworking. Sand samples collected from late Quaternary, wave-dominated Tiber-delta deposits are similar in composition to the modern Tiber River, suggesting similar provenance for the paleo- and modern Tiber River. However, lower percentages of siliciclastic sedimentary lithic fragments indicate that the clastic sedimentary succession now exposed in the upper reaches of the Tiber River, may have not been part of the paleo-Tiber drainage basin at ~860-240 Ka. Results show that tectonism following the ~840-240 Ka volcanic activity in the Sabatini, Cimini, Vulsini and Albani volcanic centers played a major role controlling stream network reorganization in the Tiber Drainage basin and resulted in enhanced volcaniclastic input from ash fall and recycling of lavas and pyroclastic flow deposits. In the Tiber River-Deltaic system, it appears that tectonic signatures override glacio-eustatic sea-level fluctuations (e.g., volume of sediment produced vs. sea-level changes), and that volcanism, which supplied volcanic lithics and associated phenocrysts, and paleosol development associated with thermal uplift controlled the overall composition of the high-rank (3rd-order) Ponte Galeria depositional sequence. Sedimentary processes (e.g., quartz/feldspar and quartz/lithic ratios), post-depositional weathering processes (e.g., amount of carbonate grains), and deposition from coeval and instantaneous pyroclastic events (e.g. volcaniclastic-rich sand) are the dominant processes that produce compositional changes in lower-rank (4th-order) depositional sequences. This work tests the effectiveness of using variation in sand composition as a tool in sequence stratigraphy.

▼ The consumption of freshwater fish and seafood is the main source of mercury (Hg), a widespread neurotoxic pollutant, in humans, a fact which has sparked decades of research on Hg cycling in aquatic systems. More specifically, the formation and bioaccumulation of methylmercury (MeHg) is of particular importance because it biomagnifies through aquatic food webs, resulting in relatively high levels in predatory fish despite typically low concentrations in the surrounding water. The main goal of this thesis was to assess how various watershed-level processes affect Hg bioaccumulation and biomagnification through freshwater food webs across the relatively pristine Attawapiskat Drainage Basin (ADB) in the remote Far North of Ontario. This watershed overlaps with the mineral-rich region known as the “Ring of Fire” which is expected to be heavily developed in the coming decades, likely altering the physico-chemical environments of surrounding lakes and rivers. In total, 58 lakes and river sites across the ADB were sampled for surface water quality, aquatic macroinvertebrates, and fish from 2014 to 2016. Water samples were analyzed for 39 chemical parameters including total Hg (THg; the sum of all Hg species) and MeHg concentrations ([MeHg]). Biotic samples were analyzed for [THg] and/or [MeHg], as well as carbon and nitrogen stable isotope ratios, which are indicative of an animal’s food web position. In Chapter 1 of this thesis, I provide an overview of our current knowledge on Hg cycling in aquatic systems of the boreal region. In Chapter 2, I present an extensive assessment of the chemical, physical, and ecological gradients across the ADB, and an analysis of the relationships between Hg and these environmental gradients. I determined that less productive systems with higher concentrations of dissolved organic matter (DOM) had higher aqueous and biotic [Hg]. In Chapter 3, I examined how changes in the quality of DOM across the ADB relate to [Hg] in water and biota. Findings from this study suggest that more labile DOM complexes enhance MeHg bioaccumulation into food webs, while systems with more humic and aromatic DOM had higher aqueous total [Hg]. The fourth chapter critically examined the speciation of Hg in fish from across the ADB and showed substantially lower percentages of MeHg (relative to total Hg) in muscle of smaller-sized fish, particularly those which feed on littoral-based food webs and had higher lipid content in their tissue. These novel findings challenge the general assumption, used in many biomagnification studies and consumption guidelines, that all fish muscle tissue has > 95% MeHg. Finally, in Chapter 5, I discuss the implications of my research for subsistence fishers, specifically those from remote communities, where freshwater fish are important for both culture and sustenance. Here I developed some preliminary approaches to better communicating the risks and benefits of consuming fish when presenting fish tissue contaminant results in remote northern…

Dissertação de Natureza Científica para obtenção do grau de Mestre em Engenharia Civil na Área de Especialização de Hidráulica

Na drenagem de vias de comunicação, o escoamento ao longo de canais de drenagem com inclinação elevada e à saída de passagens hidráulicas pode criar erosões que põem em risco a funcionalidade e segurança das infraestruturas construídas e também a segurança dos utilizadores. Para atenuar este problema, sempre que se justifique, devem prever-se obras de dissipação de energia que alterem as condições do escoamento, de forma a torná-las compatíveis com as características de resistência do material do leito e das margens. As obras de dissipação de energia podem ser de diversos tipos, desde simples proteções com tapetes de enrocamento, até estruturas em betão, localizadas ou contínuas. As condições ao longo dos canais, nos locais de descarga e a jusante de passagens hidráulicas, têm de ser avaliadas de forma a decidir qual a melhor proteção a utilizar em cada caso. A escolha do tipo de estrutura a adotar depende de fatores relacionados com as características do escoamento, condições locais, critérios de aplicabilidade de cada estrutura e aspetos económicos. Procurou-se neste trabalho estabelecer uma orientação para a escolha do dispositivo de dissipação mais apropriado perante cada situação, através da elaboração de árvores de decisão, que constituem ferramentas de auxílio na resolução deste tipo de problemas. O dimensionamento das estruturas de dissipação utiliza metodologias próprias sugeridas por diferentes autores para cada uma delas e utiliza como elementos de base os dados hidrológicos e hidráulicos usados no projeto dos órgãos de drenagem a que estão associadas (canais a céu abertoe/ou passagens hidráulicas). O estudo das soluções de dissipação de energia realizado no âmbito deste trabalho, baseia-se em pesquisa bibliográfica de artigos científicos, publicações técnicas, manuais de drenagem e em teses de mestrado relacionadas com o tema.

In roads’ drainage, the flow along the drainage channels with high inclination and culvert outlet can create erosions that endanger the functionality and safety of the constructed infra-structures as well as the users' safety. In order to alliviate this problem, when necessary, energy dissipation works that modify the flow conditions shall be provided with the intention of making them compatible with the strenght properties of the bed and margins’ materials. There are several types of energy dissipation works, from simple protections with riprap apron, to concrete structures, located or continuous. The conditions along the channels, in the discharge sites and downstream the hydraulic passages, must be evaluated in order to decide which protection is best to use in each case. The choice of protection to adopt relies on factors related with the flow characteristics, local conditions, applicability criteria of…

Tese de Doutoramento em Planeamento Urbanístico

A Questão: Enquanto projectistas (agentes privilegiados de transformação do território) qual é o papel que arquitectos e urbanistas podem representar num mundo que se quer mais sustentável, ou como contribuir para alcançar sustentabilidade? O Tema: Em termos gerais, esta dissertação pretende contribuir para a definição de um enquadramento intelectual de base holística. Em particular, pensa-se que este enquadramento intelectual possa vir a servir de suporte para o desenvolvimento de uma metodologia que promova a sustentabilidade – em planeamento do território, planeamento urbano assim como em arquitectura. Para este efeito, o território em estudo foi dividido em bacias de drenagem, tendo sido seleccionada a Bacia de Drenagem a Norte de Abrantes para experimentar a aplicação de alguns conceitos que se consideraram pertinentes. O Problema: Nesta dissertação assume-se que um dos problemas actuais, com o qual a Sociedade Global se depara, é o da fragmentação. Acresce ainda o facto de este problema/circunstância ser transversal à grande maioria das actividades humanas. Com efeito, existe fragmentação do ponto de vista do território, do ponto de vista social, e do ponto de vista do conhecimento Esta fragmentação resulta da forma em como a Sociedade Global vê e age sobre a Biosfera. Supõe-se que a causa para esta fragmentação assente sobre o paradigma do reducionismo e da compartimentalização. Por sua vez, estes paradigmas estão na base de um enquadramento intelectual que vem da época do Iluminismo. A fragmentação mencionada é visível no sistema educativo que se encontra dividido em dezenas de áreas e disciplinas diferentes, cada uma com as suas subcategorias, e em cujos seus adeptos/profissionais ou docentes geralmente não comunicam suficientemente entre si. No sistema legal e administrativo verificam-se sobreposições e desordens hierárquicas, tanto no conteúdo dos planos territoriais e dos seus regulamentos, como da própria divisão administrativa do território – traçada por linhas e fronteiras que fazem pouco sentido do ponto de vista ecológico. No sistema de controlo das infracções aos planos e condicionantes correspondentes, ou nas pressões políticas que se sobrepõem e se interpõem às questões do território ou do ambiente, é também assinalável esta mesma fragmentação. Em todo o caso, o enquadramento intelectual subjacente a esta fragmentação tem sido adequado, e tem decididamente acompanhado e apoiado o progresso dos últimos 250 anos. Porém, a velocidade e a complexidade com que os progressos humanos se têm verificado (em termos científicos, sociais, informáticos, em transportes e comunicações, etc.) desde o final da 2ª Guerra Mundial, têm colocado pressões antropogénicas excessivas. Estas pressões fazem-se sentir a todos os níveis e sobre todos os ecossistemas da Biosfera, confirmando assim a premência de se arquitectar e de se estabelecer um novo enquadramento intelectual. A Hipótese: Partindo então do princípio que é necessário o desenvolvimento de um novo…

O presente trabalho consiste no zoneamento e hierarquização das áreas de risco geomorfológico identificadas na Bacia Hidrográfica do Arroio Cadena, Santa Maria – RS. Para alcançar os objetivos propostos foram coletadas informações socioeconômicas e ambientais da área estuda. Desta forma construí-se a base cartográfica e o banco de dados gerenciados por um SIG (SPRING). A metodologia utilizada permitiu o cruzamento das variáveis ambientais consideradas (declividade, geologia, rede hidrográfica) com o Padrão Urbano da Bacia Hidrográfica e a ocorrência de eventos/acidentes, possibilitando identificar quatro situações de risco: Iminente, alto, médio e baixo. Os processos da dinâmica superficial que provocam circunstâncias de risco estão relacionadas em maior proporção a dinâmica fluvial, já os processos vinculados a dinâmica das vertentes provocam risco em menor proporção na área estudada. As áreas com maiores riscos estão associadas as áreas planas do curso principal do Arroio de Cadena. Os riscos mais comuns são as inundações/alagamentos e as erosões de margem. Estes eventos acontecem em função das ocupações desordenadas ao longo do canal. O mapa de risco geomorfológico foi construído em função dos seguintes parâmetros: morfologia, características geológicas - geotécnicas, declividade, ocupação do solo e os perigos associados. As intervenções estruturais realizadas pelo poder público municipal ao longo do tempo, inclusive com mudanças no curso do arroio não conseguiram conter a expansão das áreas de risco na Bacia Hidrográfica do Arroio Cadena, apenas mudaram-nas de lugar.

The present work consists of the zoning and hierarchization of the risk areas identified in cadena creek’s drainage basin, Santa Maria - RS. For to reach the proposed objectives, socioeconomic and environmental information of the area were collected in this study. This way we were built the cartographic base and the database managed by a SIG (SPRING). The methodology used permitted to weigh environmental variables with urban drainage basin and the hazards occurrences, was possible to identify four risk situations: Imminent, high, medium and low. The superficial dynamics processes that cause risk have large relationship with the fluvial dynamics, while the linked processes the dynamics of the slopes to cause risk in smaller proportion in the studied area. The areas with the largest risks were identified and are associated to flat surfaces on the border of the principal course of the Cadena Creek. The most common hazards are the floods and the erosion from riverside. This events occur associated with disorderly occupations and houses are jerry-built. The Geomorphologic risk map, was built up by zoning units considering the following parameters: morphology, geologycal-geotetchnical characteristics, slope gradients, activities of man and the hazards associated. The structural interventions accomplished by the municipal public power along the time, besides with changes in the course of the stream didn't get to contain the expansion of the risk areas in…

A presente pesquisa aborda a contextualizaÃÃo geoambiental da sub-bacia hidrogrÃfica do rio Figueiredo, como um subsÃdio ao planejamento ambiental. Tem-se como principal objetivo realizar uma anÃlise ambiental integrada da sub-bacia, destacando a capacidade de suporte dos seus recursos naturais e as formas de uso e ocupaÃÃo. Assim, a pesquisa se estruturou em trÃs etapas principais. A primeira estÃ voltada Ã pesquisa documental, bem como ao levantamento de dados secundÃrios da Ãrea de estudo. A segunda diz respeito ao levantamento da base geocartogrÃfica e de imagens de satÃlites. A terceira se volta Ã parte prÃtica atravÃs dos trabalhos de campo, interpretaÃÃo das imagens de satÃlites e produÃÃo cartogrÃfica. Como principais resultados, verificou-se que a sub-bacia possui os seguintes sistemas ambientais: planÃcies fluviais e Ãreas de inundaÃÃo sazonal, depressÃo sertaneja, que se divide nos sertÃes de Alto Santo, Iracema/Potiretama, Pereiro/ErerÃ, cristas residuais, maciÃo residual do Pereiro e patamares da chapada do Apodi. Esta sub-bacia apresenta processos de degradaÃÃo ambiental e riscos de desertificaÃÃo, pois possui condiÃÃes climÃticas semiÃridas e atividades humanas que comprometem a capacidade de suporte dos seus recursos naturais, entre elas a pecuÃria, a agricultura e o extrativismo vegetal, cujas tÃcnicas de utilizaÃÃo sÃo inadequadas. Neste contexto, o reconhecimento das potencialidades e limitaÃÃes naturais da bacia Ã de suma importÃncia para as diretrizes ambientais.

This research approaches the issue of integrated studies as an aid to environmental planning, having as the case study the sub-basin of the Rio Figueiredo. This river is one of the main tributaries of the Jaguaribe drainage basin, located in the eastern portion of the state of Ceara, Brazil. It has as its main objective to conduct an environmental analysis of the integrated sub-basin, highlighting the carrying capacity of its natural resources and ways to use and occupation, with a view to supporting environmental planning. For this purpose, its specific objectives are: to identify the environmental systems and types of use and occupation of their natural resources to investigate the main environmental problems in the sub-basin set, relating the causes and consequences; make a list of the floristic composition of the environmental systems aiming to realize the environmental degradation from the loss of biodiversity. This research was structured in three main stages. The first one is focused on documentary research, as well as the collection of complementary data on the study area. The second concerns the collecting of the geocartographic base data and satellite images. The third will discuss a practical field work through the interpretation of satellite images and cartographic production. The main results showed that the sub-basin has four environmental systems: fluvial plains and areas of seasonal flooding, depression hinterland, which is divided in the backlands of Alto Santo, Iracema/Potiretama, Pereiro/ErerÃ, residual ridges,…
