1. Pešić Vesna. Procena rizika po kvalitet površinskih vodnih tela na osnovu identifikovanih koncentrisanih izvora zagađenja.

Degree: 2016, University of Novi Sad

Istraživanja u ovom radu su obuhvatila primenu koncepta analize značaja pritisaka i  uticaja i metoda za identifikaciju i klasifikaciju  izvora pritisaka; karakterizaciju i analizu pritisaka; procenu statusa vodnih tela i procenu uticaja/rizika da se ne dostigne njihov dobar ekološki status/potencijal. Ukupan broj registrovanih zagađivača na teritoriji AP Vojvodine iznosi 185, trenutno radi njih 130. Najviše zagađivača svoje otpadne vode  ispušta u Tisu, DTD Vrbas-Bezdan i Begej, koji su recipijenti 61% od ukupne količine  otpadnih voda. Skoro 70% od ukupnog broja zagađivača pripada sektoru prerađivačke  industrije, a među njima je najzastupljenija proizvodnja prehrambenih proizvoda i pića. Prosečna dnevna količina ispuštenih otpadnih voda iznosi oko 140.000 m3/dan.  Ukupno organsko zagađenje koje se emituje u vodotoke na području AP Vojvodine, a  potiče  od otpadnih voda iznosi 33 tHPK/dan i 15 tBPK/dan. Polovina zagađivača svoje otpadne vode ispuštaju bez ikakvog tretmana, četvrtina njih poseduje primarni tretman prečišćavanja, dok tercijarni tretman primenjuje svega 3% zagađivača. Veoma je mali broj zagađivača kod kojih su emitovane konecentracije usklađene sa propisanim graničnim vrednostima emisije, za nutrijente je to oko 50%, dok je za organske materije samo četvrtina  od ukupnog broja zagađivača. Od 37 vodotoka, samo tri se klasifikuju u klasu 2, što odgovara dobrom kvalitetu voda. Kvalitet najvećeg broja vodotoka odgovara   slabom ili lošem statusu/potencijalu (tj. klasama 4 ili 5). Najveća odstupanja od dobrog statusa/ potencijala su u sadržaju nutrijenata i parametara kiseoničnog  režima. Rezultati  su pokazali da su polutanti visokog rizika najčešće nutrijenti i parametri kiseoničnog režima, što najverovatnije predstavlja negativan uticaj ispuštanja otpadnih voda. Ukupno  opterećenje zagađujućih materija a time i broj vodotoka na kojima je premašeno ciljano opterećenje znatno raste sa porastom emitovanog opterećenja iz  koncentrisanih izvora, ali i  sa smanjivanjem protoka vode u vodotocima. Najveći broj vodotoka (20) na kojima je premašeno ciljano opterećenje je u slučaju HPK i fosfora. U slučaju postizanja graničnih vrednosti emisije kod svakog zagađivača, broj vodotoka na kojima je premašeno ciljano opterećenje se smanjuje za 15-50%, zavisno od parametara, pri čemu broj vodotoka na kojima je premašeno ciljano opterećenje ne zavisi od veličine emitovanog opterećenja nego samo od protoka vode u kanalima.

Research in this study included the concept of pressure and influence significance analysis as well as the methods for identification and classification of the pressure sources: characterisation and analysis of  pressures; assessment of the…

2. Daeden, Jonathan. Analyse des pressions anthropiques sur l’environnement littoral européen et français : Analysis of anthropogenic pressures on the French and European coastal environment.

Degree: Docteur es, Géographie physique, humaine, économique et régionale, 2015, La Rochelle

La gestion et la conservation des littoraux exigent la synthèse de données géographiques sur la répartition et l'intensité des activités humaines et sur le cumul de leurs impacts sur les écosystèmes côtiers marins et terrestres. Actuellement, à l’échelle du littoral européen ou français, peu d’études offrent une vision globale des risques sur les habitats terrestres et marins. Comment s’y répartissent les pressions humaines sur la biodiversité ? Comment mieux définir le système littoral et ainsi améliorer la gestion de ce territoire ? A l’échelle européenne, à l’aide de 24 pressions anthropiques issues d’EUROSTAT sur une classification NUTS, nous avons découpé le littoral terrestre européen en bandes de 10 km jusqu’à une limite de 100 km et identifié la répartition et l’intensité relative des pressions sur les environnements côtiers. Nous avons ainsi montré que la grande majorité des pressions se situent directement sur le trait de côte et les 30 premiers kilomètres, puis diminue fortement jusqu’à la limite des 100 km. Ce découpage du littoral européen nous a aussi permis, à l’aide d’analyses factorielles des correspondances couplées à de la classification hiérarchique ascendante, de diviser les territoires littoraux en 4 groupes cohérents présentant les mêmes pressions et intensités relatives à l’échelle de l’Europe. A l’échelle française, nous avons également développé un modèle spatial pondéré par dires d’experts basé sur la géolocalisation de 15 pressions anthropiques pour 81 habitats biophysiques marins et terrestres présents sur les littoraux français métropolitains. L’information est synthétisée sous la forme de score appliqué à un maillage composé de 26000 cellules de 25 km². Cette méthode de scoring cumulative, dans un modèle additif des impacts anthropiques, nous montre les aires à risques à la fois sur le territoire marin et terrestre. Encore une fois, les zones les plus affectées par les perturbations humaines sont les plus proches du littoral. A contrario, les zones les moins affectées sont celles avec une bathymétrie forte et celles avec une élévation importante. Nous avons finalement développé un site web participatif qui comporte de la SIG intégrée pour permettre la collecte et la diffusion de l’analyse de ces pressions anthropiques sur la France métropolitaine en suivant notre modèle additif et permet à des échelles plus locales de restituer notre analyse à tout type d’utilisateur. Au final, peu de zones ne sont pas affectées par les activités humaines (0,1%) et au contraire, une fraction importante présente de très forts risques (4,8%). Les risques sont de plus en plus forts en se rapprochant du trait de côte. Ces analyses et les cartes développées sont des outils permettant de mieux comprendre les enjeux de conservation pour la mise en œuvre d’une gestion des socio-écosystèmes littoraux et permettront de mieux cibler les priorités dans la conservation de notre territoire à échelle continentale, nationale ou locale.

3. Md Noar, Nor. Wave impacts on rectangular structures.

Degree: PhD, 2012, Brunel University

There is a good deal of uncertainty and sensitivity in the results for wave impact. In a practical situation, many parameters such as the wave climate will not be known with any accuracy especially the frequency and severity of wave breaking. Even if the wave spectrum is known, this is usually recorded offshore, requiring same sort of (linear) transfer function to estimate the wave climate at the seawall. What is more, the higher spectral moments will generally be unknown. Wave breaking, according to linear wave theory, is known to depend on the wave spectrum, see Srokosz (1986) and Greenhow (1989). Not only is the wave climate unknown, but the aeration of the water will also be subject to uncertainty. This affects rather dramatically the speed of sound in the water/bubble mixture and hence the value of the acoustic pressure that acts as a maximum cutoff for pressure calculated by any incompressible model. The results are also highly sensitive to the angle of alignment of the wave front and seawall. Here we consider the worst case scenario of perfect alignment. Given the above, it seems sensible to exploit the simple pressure impulse model used in this thesis. Thus Cooker (1990) proposed using the pressure impulse P(x, y) that is the time integral of the pressure over the duration of the impact. This results in a simplified, but much more stable, model of wave impact on the coastal structures, and forms the basis of this thesis, as follows: Chapter 1 is an overview about this topic, a brief summary of the work which will follow and a summary of the contribution of this thesis. Chapter 2 gives a literature review of wave impact, theoretically and experimentally. The topics covered include total impulse, moment impulse and overtopping. A summary of the present state of the theory and Cooker’s model is also presented in Chapter 2. In Chapter 3 and Chapter 4, we extend the work of Greenhow (2006). He studied the berm and ditch problems, see Chapter 3, and the missing block problem in Chapter 4, and solved the problems by using a basis function method. I solve these problems in nondimensionlised variables by using a hybrid collocation method in Chapter 3 and by using the same method as Greenhow (2006) in Chapter 4. The works are extended by calculating the total impulse and moment impulse, and the maximum pressure arising from the wave impact for each problem. These quantities will be very helpful from a practical point of view for engineers and designers of seawalls. The mathematical equations governing the fluid motion and its boundary conditions are presented. The deck problem together with the mathematical formulation and boundary conditions for the problem is presented in Chapters 5 and 6 by using a hybrid collocation method. For this case, the basis function method fails due to hyperbolic terms in these formulations growing exponentially. The formulations also include a secular term, not present in Cooker’s formulation. For Chapter 5, the wave hits the wall in a horizontal direction and for Chapter 6, the wave hits…
