▼ The Lower Arkansas River Valley in southeastern Colorado is an irrigated, agricultural valley suffering from high concentrations of nutrients (Nitrogen N; phosphorus P) and salts in the coupled groundwater-surface water system. The majority of data collection efforts and associated spatial analysis of concentrations and
mass loadings from the aquifer to the stream network have been performed at the regional scale (> 500 km²). These regional scale assessments have indicated that river riparian areas play a major role in controlling nutrient
mass flux to the Arkansas River and its tributaries. However, the water and nutrient
mass exchange within the riparian-stream system have not yet been investigated in detail. The objective of this thesis is to enhance understanding of hydro-chemical stream-aquifer processes at the reach scale (< 5 km) along the main stem of the Arkansas River and along a major tributary. Using a suite of in-stream instruments and observation wells, a 4.7 km reach of the Arkansas River and a 2 km reach of Timpas Creek were monitored to quantify spatio-temporal groundwater-surface water interaction and
mass inputs and outputs of nutrients. The total volume of water flowing into and out of each study reach was quantified using existing stream gages for upstream flow measurements and developing new stream gages for downstream flow measurements. Stage-discharge relationships were developed at the downstream locations using in-stream water level loggers and periodic flow measurements using Acoustic Doppler Velocimeters (ADVs). Monitoring included growing season length and 24-hour monitoring of flow and water quality. Using these monitoring data,
mass balance calculations were used to quantify groundwater-surface water interactions and nutrient
mass exchanges and loadings. For growing season length analysis, surface water samples were collected and in-situ measurements were made at the stream gaging sites every two weeks during the study period to provide a data set on fluxes into and out of each reach during the irrigation season. The two 24-hour sampling events were performed in June and October of 2014 to compare groundwater-surface water exchange and
mass loadings at the beginning and end of the growing season. Composite water quality samples for total N, nitrate as nitrogen (NO₃‾; as N), nitrite as nitrogen (NO₂‾; as N), ammonium as nitrogen (NH₄⁺ as N), total P, and dissolved salts were collected at the gage locations every 2 hours using ISCO automatic samplers along with in-situ measurements of water level, temperature, and specific conductance. Water quality samples, along with in-situ measurements, were also collected from transects of shallow monitoring wells installed in the riparian corridor and on the banks of each reach during sampling events. These water quality data, as well as estimated gradients of groundwater hydraulic head between monitoring wells, were used to inform
mass loading calculations. Growing season length monitoring results from the Arkansas River show…

▼ A mass balance technique was used to investigate the hydrogeochemistry of the Kafixe river as it crosses the Copperbelt mining area between Raglans farm and Machiya feiTy. Tlie study is done by examining the mass flow-rates often chemical parameters, namely: total dissolved solids, total suspended soUds, elemental cadmium, cobalt, copper, hon, manganese, lead, barium and sulphur. In this study, the aqueous concentrations in the rivers where obtained from samples collected at four sampling stations along the Kafiie river and one station on the Mwambashi river. The volume discharge rates were obtained from the Department of Water aflfaks. Further data was obtained from Zambia ConsoHdated Copper Mines Limited.The mass flows for the parameters are computed on a monthly basis as the average of the product of the concentrations of the parameters and discharge rates for the particular month.Results obtained indicate that the mass flows of these chemical constituents increase after the river enters the mining areas and decrease after exiting the areas. W\IQ relative impact of the mining operations on the river basin varies fiom place to place and chemical to chemical. In the Mwambashi river on one hand, practically all the total dissolved sohds flowing in the river during the dry season seem to emanate from mining operations. On the other hand, dissolved uon flow rates at certain times of the year actually drop as the river enters the area of the mining operations.Redox conditions also seem to have an effect on the speciation of metals hke iron, lead and manganese. Photosynthesis by aquatic plants has been found to determine the level of dissolved oxygen and the redox potential level.Copper flows from Fishers farm to Machiya appear to be affected by iron speciation as a result of the ability of iron oxyhydroxides in adsorbing various heavy metals. Hie same seems to apply to lead.
For cadmium, mining activities may not be major factor m the mobihsation of the metal since the biggest input of the metal appears to come between Fishers farm and Machiya ferry samphng point. Most of the mining activities discharge their effluent into the Kafiie at points upstream of Fishers farm.
This study has thrown some hght on the hydrogeochemical processes taking place in the Kafiie river. It has shown how mine effluent is effecting the water quality in the Kafue river and how the river itself effects the effluent.

▼ Mountain glaciers are already responding to climatic warming, and are expected to
make a substantial contribution to sea-level rise in the coming decades. The aim of
this investigation in the New Zealand Southern Alps was to improve our
understanding of snow accumulation variability on mid-latitude maritime glaciers,
in order to allow for better estimation of future glacier
mass balance. The specific
aim was to investigate snow accumulation processes at a range of spatial and
temporal scales, focussing on synoptic-scale atmospheric circulation influences,
moisture sources for snow accumulation and local-scale dependencies of snow
accumulation in relation to topography. A range of methods were utilised including
direct measurement, snow and ice core analysis, statistical analysis and modelling.
Snow accumulation in the Southern Alps was found to be derived predominantly
from the Tasman Sea, and deposited during low pressure troughs and fronts.
Although precipitation increased with elevation, wind processes redistributed this
mass. On a ~monthly timescale this redistribution caused an unexpected result,
namely that wind deflation of snow on Franz Josef Glacier countered the effects of
greater accumulation, and total accumulation was similar at both Franz Josef and
Tasman Glaciers over this period. These processes make it challenging to simulate
snow accumulation patterns by simply extrapolating snowfall over an orographic
barrier from lowland climate station data. On an inter-annual basis, temperature,
especially during the ablation season, had most influence on net accumulation, and
warm summers served to homogenise winter variability. Consequently, atmospheric
circulation patterns that affect summer temperature, for example the El Niño
Southern Oscillation (ENSO) and the Southern Annular Mode (SAM) also influence
inter-annual variability in net accumulation.
Together, these results highlight the dependence of maritime glaciers in the New
Zealand Southern Alps on the prevailing westerly circulation. Although some
uncertainty surrounds how global warming will affect atmospheric circulation and
synoptic weather patterns, the results of this research indicate that New Zealand
glaciers can be expected to lose significant
mass in the coming decades if the
current positive trend in the SAM continues, and if La Niña events (positive ENSO)
become more frequent.

Determining Greenland Ice Sheet sensitivity to regional climate change: one-way coupling of a 3-D thermo-mechanical ice sheet model with a mesoscale climate model.

▼ The Greenland Ice Sheet, which extends south of the Arctic Circle, is vulnerable to melt in a warming climate. Complete melt of the ice sheet would raise global sea level by about 7 meters. Prediction of how the ice sheet will react to climate change requires inputs with a high degree of spatial resolution and improved simulation of the ice-dynamical responses to evolving surface mass balance. No Greenland Ice Sheet model has yet met these requirements.A three-dimensional thermo-mechanical ice sheet model of Greenland was enhanced to address these challenges. First, it was modified to accept high-resolution surface mass balance forcings. Second, a parameterization for basal drainage (of the sort responsible for sustaining the Northeast Greenland Ice Stream) was incorporated into the model. The enhanced model was used to investigate the century to millennial-scale evolution of the Greenland Ice Sheet in response to persistent climate trends. During initial experiments, the mechanism of flow in the outlet glaciers was assumed to be independent of climate change, and the outlet glaciers' dominant behavior was to counteract changes in surface mass balance. Around much of the ice sheet, warming resulted in calving front retreat and reduction of total ice sheet discharge. Observations show, however, that the character of outlet glacier flow changes with the climate. The ice sheet model was further developed to simulate observed dynamical responses of Greenland's outlet glaciers. A phenomenological description of the relation between outlet glacier discharge and surface mass balance was calibrated against recent observations. This model was used to investigate the ice sheet's response to a hypothesized 21st century warming trend. Enhanced discharge accounted for a 60% increase in Greenland mass loss, resulting in a net sea level increment of 7.3 cm by year 2100. By this time, the average surface mass balance had become negative, and widespread marginal thinning had caused 30% of historically active calving fronts to retreat. Mass losses persisted throughout the century due to flow of dynamically responsive outlets capable of sustaining high calving rates. Thinning in these areas propagated upstream into higher elevation catchments. Large drainage basins with low-lying outlets, especially those along Greenland's west coast and those fed by the Northeast Greenland Ice Stream, were most susceptible to dynamic mass loss in the 21st century

▼ The occupational indoor air quality (IAQ) during
construction plays a major role in workers' health and safety as
construction activities frequently generate airborne pollutants.
Exposure to dusts, fumes, fibres and volatile organic compounds
(VOCs) can cause health issues such as lung cancer, asthma and
silicosis. The occupational exposure limits for hazardous airborne
pollutants in the workplace is legislated by the Alberta
Occupational Health and Safety Code. This thesis proposes a
methodology to predict the occupational indoor air quality during
construction activities utilizing Building Information Modeling
(BIM). The single zone mass balance model was used to determine the
indoor pollutant concentration; the model was integrated with BIM
to calculate the air pollutant concentration during construction
activities. This method allows the stakeholders to determine the
indoor air quality before actual construction work. A case study
demonstrates the proposed methodology during a drywall sanding
activity to verify its effectiveness.

▼ Numerous recent studies have documented dynamic changes in the behaviors of large marine-terminating outlet glaciers and ice streams in Greenland, the Antarctic Peninsula, and West Antarctica. However, fewer observations of outlet glaciers and ice shelves exist for the East Antarctic Ice Sheet. In addition, most recent surface velocity mappings of the Lambert Glacier-Amery Ice Shelf system (LAS) are derived for the time period of 1997-2000. From this research, surface velocity measurements provide a more extended view of the behavior and stability of the LAS over the past two decades than can be gleaned from a single observational period.
This study uses remote sensing to investigate whether significant changes in velocities have occurred from the late 1980’s through the late 2010’s and assesses the magnitude of
mass balance changes observed at the grounding line. To accomplish this goal, surface velocities of the LAS from late 1980’s to late 2010’s for three separate time periods are measured. The observed surface velocities of the LAS ranged from 0 to 1300 m yr^-1 during 1988-1990. A slight slowing down is detected in the central Amery Ice Shelf front by analyzing the surface velocity measurements made along the centerlines.
The
mass balance is the difference between snow accumulation and the outflux of the grounded LAS and is calculated for individual sub-basin during the three time intervals of 1988-1990, 1999-2004, and 2007-2011 to illustrate the
mass balance variation under sub-basin level. The flux gates of the Lambert Glacial sub-basin combined with the Mellor Glacial and the Fisher Glacial sub-basin appear to be the largest outlet of the grounded ice of the LAS. The ice
mass transported from the interior region through the three flux gates in total is 43.58 Gt yr^-1, 36.72 Gt yr^-1, and 38.61 Gt yr^-1 respectively for the three time intervals above. The sub-basins in the eastern side appear differently than the western side. The outfluxes of the eastern sub-basins vary from 15.85 to 18.64 Gt yr^-1, while the western outfluxes vary from 15.85 to 18.64 Gt yr^-1.
The grounded LAS has discharged ice from 84.55 to 81.60 Gt yr^-1 and to 79.20 Gt yr^-1 during 1980s-1990s and 1990s-2000s. Assuming the snow accumulation distribution is stable, the grounded LAS
mass lose has increased 2.95 Gt yr^-1 from 1980s to 1990s and 2.40 Gt yr^-1 from 1990s to 2000s. These results indicate insight into the stability of the Amery Ice Shelf over the last few decades.

▼ A
mass-
balance modeling approach has been applied to gain an improved understanding of the relative contributions of phosphorus loading from various sources into a freshwater lake with cage-aquaculture in Ontario. All cage-aquaculture in Ontario is located within Lake Huron and Georgian Bay of the Great Lakes where concerns about potential environmental issues are constraining growth of the industry. Phosphorus is of particular concern for cage-aquaculture operations in Ontario since this nutrient may accelerate eutrophication of freshwater. Sound scientific information is needed for the Ministry of Environment lake managers to make defensible decisions to move the industry forward in a sustainable manner. Lake Wolsey is located on Manitoulin Island in Lake Huron, Ontario. The lake is connected to the North Channel by a small inlet where water exchanges periodically. A cage-aquaculture operation was established in 1986 and has an average annual production of approximately 250 metric tonnes of rainbow trout. We have estimated total phosphorus loadings from eight sources of inputs and three sinks from the lake. We then applied a sensitivity analysis to establish parameters that require empirical measurement and field validation. Results show non-point sources as the leading contributor of total phosphorus to Lake Wolsey (40%, 1120 kg) followed by the farm (32%, 915 kg), groundwater (11%, 305 kg), and dwellings (8%, 219 kg), internal phosphorus load from the hypoxic hypolimnion mid-lake (7%, 186 kg), precipitation (3%, 79 kg) and leaf litter (0.3%, 8 kg). Results of the sensitivity analysis show non point sources to be the most significant parameter in terms of total phosphorus loading, followed by the lake sedimentation, then the contribution by the aquaculture operation. This is followed by the exchange via the inlet, groundwater, dwellings, the internal phosphorus, sportfishing, precipitation and leaf litter. Information from this project will provide water quality managers with scientific information to aid in decisions pertaining to policy and regulatory approaches for water quality risk assessment and management of cage-aquaculture in Ontario.

▼ Small perturbations in climate can produce measurable changes to the size of a glacier. Documenting such changes is important for quantifying water storage changes, and understanding glacier-climate interactions. By using all available geodetic data, such as Landsat imagery, Shuttle Radar Topography Mission, GNSS and photogrammetric techniques, as well as ground penetrating radar for the construction of a bed DEM, it is found that Brewster Glacier decreased in volume from 1967 to 2017, losing ∼56% of its volume, with a period of volume increase of ∼10% from 1986 to 1997. The overall pattern of geodetic
mass balance is similar to the glaciological
mass balance record, however, the geodetic method tends to show more negative values by an average of ∼0.6 m w.e. Contrary to many other New Zealand glaciers, which experienced an advance from 1983 to 2008, Brewster Glacier continued to retreat by 390 m during the study period, at an average rate of 7.8 m a⁻¹, but at a significantly reduced rate of ∼2 m a⁻¹ from 1997 until 2005. By comparing the records of Brewster Glacier and Fox and Franz Josef glaciers, we explore the differences in response and reaction times resulting from glacier area-altitude distribution, and climatic setting. Furthermore, DEMs produced by this study are now available for use by a New Zealand wide glacier monitoring programme.

▼ Multiple authors have delineated the Colorado Front Range (COFR) landscape into distinct elevational zones with respect to contemporary geomorphologic processes, landscape development, and sediment dynamics in bedrock canyons. Several studies have estimated denudation rates using rates of post-fire erosion, alpine soil erosion, beaver dam sedimentation, and cosmogenic tor erosion, but comparison is limited due to differences in the time scale captured by different measurements. I address this gap by using cosmogenic 10Be to measure denudation rates in three process domains: flat Front Range summits, five unglaciated watersheds above the latest Pleistocene terminal glacial moraine, and five watersheds below the moraine. Two paired bedrock outcrop and soil samples were taken on flat summits in Rocky Mountain National Park. Bedrock samples were taken from a low-lying bedrock outcrop and large boulder with accompanying colluvial soil samples from the surrounding surface. Fluvial sediment was collected for 10Be analysis from the outlets of 10 watersheds. I also conducted soil surveys in each basin to examine relationships between physical characteristics, depth of regolith, and hillslope position. Low outcrops and regolith from a glacial col saddle are denuding at four times the rate of previously published tor data, while regolith from a summit flat is eroding much more slowly and at similar rates to summit flats elsewhere in the Rockies. Basins are denuding at similar rates to cosmogenic radionuclide (CRN)-derived, basin-averaged rates in the Boulder Creek watershed and show no difference between hydroclimatic process domains. Basin morphometric parameters are not significantly related to these denudation rates. The denudation rates span into the Late Pleistocene, and are an order of magnitude lower than Holocene sedimentation rates. This implies a large increase in Holocene COFR erosion in basins not glaciated during the Pleistocene, and could reflect stronger monsoonal rain systems generating more debris flows. Denudation rates increase with the percent of coarse material processed, alluding to grain size dependency of CRN concentrations. This pattern appears to be affected by valley confinement at the sampling location. Regolith is deeper and shows a more typical pattern along hillslope fall lines on upper basins, implying that weathering rates may be higher and disturbance less frequent. Bulk geochemistry of bedrock and regolith on Big Horn Flats contains the signal of Zr-rich dust inputs that may indicate the importance of Mojave Desert source areas during the Pleistocene. Millennial-scale weathering rates assuming no dust deposition (5.8 - 10 t/km2yr) are similar to modern estimates, but uncertainty from dust inputs cannot be constrained.

▼ Twelve published papers are submitted for this
D.Sc. thesis. The papers were published in 1995 to 2009 when Roger
Braithwaite was employed by the University of Manchester. The
submitted papers relate to the general area of ‘glaciers and sea
level’ and there is a strong theme that glacier conditions differ
between regions, hence the title ‘geography of glacier mass
balance’. Paper no. 1 analyses degree-day factors from Greenland
whereby glacier melting can be calculated from temperature data.
Paper no. 2 discusses the effect of glacier mass balance changes on
global sea level rise, including a simple theoretical treatment and
estimation of the temperature-sensitivity of global sea level using
the degree-day model. The latter depends on the combined
geographies of glacier area and temperature-sensitivity of glacier
mass balance. Papers 3, 4 and 5 analyse observed glacier mass
balance from all over the world, and papers 6, 7 and 8 discuss the
modelling of mass balance with the degree-day model. A trend of
increasingly negative observed mass balance is only detectable
towards the end of the 1995-2009 period. Papers 9, 10 and 11
discuss the climate at the glacier equilibrium line altitude (ELA)
and propose a simplified approach to calibration of the degree-day
model. Paper 12 returns to the topic of global sea level change
with improved insights from papers 9, 10 and 11. Observed mass
balance variability (papers 3, 4 & 5) and modelled
temperature-sensitivity of mass balance (papers 6, 7 & 8) both
show contrasts between maritime and continental climates with lower
variability and sensitivity at high latitudes and in continental
interiors, and higher variability and sensitivity at lower
latitudes. The underlying global geography of mass balance
variability and temperature-sensitivity is therefore controlled by
the geography of annual precipitation.

▼ Differential GPS data from 2007-2014 are used to assess horizontal and vertical velocity variations of the Kaskawulsh Glacier at interannual and intra-annual timescales. These indicate that an upglacier propagating high velocity event occurs every spring at the onset of melt, and that a downglacier propagating high velocity event occurs every fall or winter after melt has finished. These events suggest that the subglacial drainage system alternates between a distributed system in the winter and channelized system in the summer and fall. In addition, there is a strong negative correlation between summer melt and velocity the following fall and winter, with strong melt years resulting in low velocities. For each additional metre of summer melt, an 8.6% average decrease in velocity is observed on the glacier the following fall-winter. These results suggest that changes in the subglacial drainage system limit the sensitivity of glacier motion to increased meltwater inputs. Glacier motion will likely show a net decrease under a warming climate due to the negative correlation between surface melt rates and ice motion and a decrease in driving stresses as a result of reduced ice thicknesses. In addition, future fall-winter velocity patterns could be accurately predicted from only a month or two of summer melt data, with May-June melt providing the best indication of fall-winter motion. This study also suggests that the common assumption that glaciers are ‘stable’ in the late fall and winter is incorrect.

▼ This thesis presents a detailed study of recent changes in the mass balance and dynamics of Penny Ice Cap (PIC), and projects its evolution under a warming climate. Mass losses from 2005-2014 were quantified from airborne altimetry elevation change measurements, and adjusted for vertical ice motion caused by firn compaction and/or ice dynamics. Mass loss from PIC increased four-fold between the mid-1990s (-1.3 ± 0.7 Gt a-1) and 2005-2013 (-5.4 ± 1.9 Gt a-1). The adjustment calculations indicate that mass loss may be overestimated by 19% if vertical motion is not properly accounted for. The velocity response to increased surface melt was quantified using satellite imagery and historical ground measurements from Highway Glacier, on the southern part of PIC. Over the period 1985-2011, the six largest outlet glaciers on the ice cap decelerated at an average rate of 21 m a-1 over the 26 year period (0.81 m a-1), or 12% decade-1. Highway Glacier decelerated by 71% between 1953 and 2009/11. The recent slowdown of outlet glaciers has coincided with increases in mass loss and an inferred reduction in basal sliding. The ice-cap-wide mass balance was modeled from 1958 to 2099 with an enhanced temperature index model. Since the mid-1990s mass balance rates over PIC have become increasingly negative. Peak mass loss is projected to occur in the late 2070s and PIC is expected to lose 16-20% of its 2014 ice volume by 2099 assuming a moderate climate warming scenario (RCP4.5). If a +2°C offset is applied to this scenario, the ice cap is expected to lose 30-40% of its initial ice volume by 2099.
These results provide the first comprehensive evaluation of the impact of vertical ice motion on mass loss derived from geodetic measurements over a large Arctic ice cap. The ice velocity record provides insights into the relationship between surface melt rates and glacier motion over the past 30-60 years. This study projects the mass change of the largest ice cap in the southern Canadian Arctic to 2099, calibrated and validated with a wealth of spatially distributed data for the first time.

▼ Soil salinity affects an estimated one billion hectares worldwide. Excess salinity inhibits plant growth, limiting crop production. This is caused by osmotic stress in saline soil, nutrient imbalance and specific ion toxicity. There have been many methods of remediation investigated, including excavation, soil washing and phytoremediation.
Phytoremediation involves the growth of plants on impacted soils to degrade or sequester contaminants. The remediation of salts relies on the uptake of ions into plant biomass where the salt is sequestered and the biomass can then be harvested. This method removes the salt from the site and leaves the top soil in place, which aids in revegetation after site remediation is completed. Plant-growth promoting rhizobacteria (PGPR) improves plant growth by lowering the levels of stress ethylene within the plant, thereby increasing the biomass available to sequester ions.
The objectives of this research were to investigate the efficiency of phytoremediation of salt impacted soils in field remediation sites. Previously isolated strains of PGPR (UW3, Pseudomonas putida; UW4, Pseudomonas putida; and CMH3, Pseudomonas corrugata) were used in field trials involving the planting of oats (Avena sativa), annual ryegrass (Lolium multiflorum), tall wheatgrass (Agropyron elongatum) and tall fescue (Festuca arundinacea C.V. Inferno). The salt tolerance of various switchgrass (Panicum virgatum L.) cultivars (Cave-In-Rock, Southlow, Forestburg, and common) was compared to tall wheatgrass and Inferno tall fescue to investigate the potential of switchgrass for phytoremediation. Improvement of seed germination under salt stress by H2O2 pre-treatment was investigated both as an individual treatment and in combination with CMH3 treatment. The ion uptake into plant biomass was iii
compared to the change in salinity, to determine how much of the decrease in site salinity is accounted for by uptake of salt by plants.
H2O2 pretreatment resulted in a 50% increase in root and shoot emergence of tall wheatgrass under 75 mM NaCl stress compared to control treatments, which matched the germination improvement observed with PGPR treatment. The combination of H2O2 and CMH3 showed a similar improvement to root emergence under stress, but had no observable effect on shoot emergence when compared to the no-H2O2-no-PGPR control. Switchgrass cultivars showed a lower germination rate than tall wheatgrass at salt levels from 0 mM to 150 mM NaCl. The measured uptake of Na+, K+, Ca2+, Mg2+ and Cl- into plant biomass during a phytoremediation field trial was able to account for approximately 70% of the observed change in salinity in 2008. In 2009 the uptake of Na+ and Cl- into Kochia scoparia, a weed species that invaded the field site after a hard frost, was able to account for 36% of the observed change in salinity.

▼ Dozens of sedimentary fans have been identified on Mars and have been interpreted as alluvial fans or deltas. However, the extent to which these deposits represent the complete eroded
mass of the valleys that drain into them, the extent to which erosion has removed fan material, and the extent to which sediment bypass occurred during fan deposition into a distal water body remain unknown. This study investigates the role of emplacement versus modification following deposition in a catalog of martian fans to determine the extent to which such deposits have been preserved. A
mass balance approach was taken; by calculating the present volumes of fans and the valleys feeding them, the percentage of eroded valley sediment that has accumulated and remained within the fan deposits can be determined. Based on measurements of 32 valley and fan volumes calculated using CTX stereo DEMs, we find two major classes of landforms: isolated inlets with lower stream orders and fans of approximately equal volume to the source valleys, and regionally-integrated valley networks with higher stream orders and much smaller fan volumes than valley volumes. If stream order correlates with valley age on Mars, then these results imply change in martian erosion and deposition patterns over time. We infer that hydrodynamic sorting in older, wetter systems resulted in preferential deposition of fines in fans formed by higher stream order valleys, and, ultimately more erosion in these fine-grained deposits, while younger, drier systems created deposits with intermixed sediment sizes that remain preserved today due to the greater protection of the fines from post-depositional erosion. These observations are consistent with a waning hydrologic cycle throughout martian history.

▼ A one-million ton hot iron per year suspension ironmaking plant has been simulated with the consideration of activity coefficient of FeO in slag by using Metsim simulation software package for calculating material balance and energy balance in this thesis. Mathematical models found in the literature for calculating the activity coefficient of FeO in slag were first selected, reviewed and assessed. Park and Lee’s regular solution model was evaluated to be the most appropriate model for this study, and was integrated with the Metsim simulation software for the simulation of the suspension ironmaking process.Six suspension ironmaking processes were simulated: one-step process with pure H2, two-step process with pure H2, one-step reformerless process with natural gas, two-step reformerless process with natural gas, one-step process with SMR-H2 and one-step process with SMR-syngas. The simulated results show that the suspension ironmaking processes with pure H2 and reformerless natural gas are more energy efficient than conventional blast furnace ironmaking process, mainly due to the direct use of iron ore concentrate and no need for coke in the suspension ironmaking processes. The reformerless suspension ironmaking process with natural gas would consume 30 – 41% less energy than the average blast furnace ironmaking process.On the basis of material balance and energy balance, the economical feasibility of the suspension ironmaking process was analyzed. Capital cost, operating cost, CO2credit and net present value were used in analyzing economic feasibility of the suspension ironmaking process.The analyzed results show that pure H2 process would require the least capital cost and receive the largest CO2 credit, but need the highest operating cost. Even without considering CO2 credit, except pure H2 process, all other suspension ironmaking processes would be profitable with positive NPV values. With sufficient CO2 credit, all suspension ironmaking processes simulated would be profitable, among which reformerless natural gas would return the best economics.Capital cost for the one-million ton per year suspension ironmakng plant with reformerless natural gas would be 414 million for one-step and 537 million for two-step, operating cost 429/tHI and 418/tHI, and NPV 333/tHI and 177/tHI without CO2 credit and 813/tHI and 795/tHI with 100/t CO2 credit, respectively.Economic sensitivity was also analyzed. Lower fuel price, lower operating cost, higher hot iron price and larger CO2 credit would all help improve the economics of the suspension ironmaking process.

▼ In the Kebnekaise Massif, Northern Sweden, the west facing glacier, Rabots glaciär, is loosing volume at a significantly higher rate than east facing, Storglaciären. By analyzing data from automatic weather stations situated on the ablation area on the glaciers we investigated the effect of meteorological differences on ablation. There was a difference in micro-climate between Rabots glaciär and Storglaciären. Generally Storglaciären had slightly warmer and drier air, had less or a thinner cloud layer but more precipitation. On both glaciers a glacier wind is dominant but high wind velocities were common especially on Storglaciären indicating a larger influence from the synoptic system. There was a good correlation for temperature and vapor pressure between the glaciers that indicate that both glaciers are strongly affected by the synoptic system. The meteorological parameters have similar effect on the ablation on the glaciers. Temperature, vapor pressure and the turbulent heat fluxes are the only meteorological parameters that suggest a linear affect on ablation. Net shortwave radiation contribute with the greatest amount of energy for ablation but decreased in relative importance as the temperature increased. Shortwave radiation, sensible and latent heat contributed with a total 184Wm-2 on Rabots glaciär and 222Wm-2 on Storglaciären. Rabots glaciär seem to have a significantly greater relative importance of the turbulent heat fluxes than Storglaciären. Although the differences in micro-climate were not great, using the ablation for Storglaciären to estimate ablation on Rabots glaciär would over estimate the ablation with 0.5m w.e..

▼ Since several decades organic micro pollutants (OMPs) have been detected in natural waters. Although appearing in very low concentrations (nanograms to micrograms per litre or even lower), the presence of more than 100.000 registered chemical substances in the European Union, of which 30.000-70.000 are in daily use, is a major reason for concern. Due to their persistent character the OMPs remain longer in the water cycle and can be transported over a longer distance than other pollutants. Current treatment facilities are not designed to remove those compounds, which causes them to end up in the environment and even in drinking water. The current problems on OMPs in the water cycle are not that the concentrations present in the water cycle are too high to guarantee the safety of drinking water, but are the long-term effects of these concentrations, the increase in concentrations (due to changing circumstances) and the unknown effect of OMPs in mixtures with other OMPs. In order to find a solution to this problem this project focusses on the following question: What is the most sustainable, applicable and cost-efficient strategy to reduce concentrations of selected micro pollutants in surface water and drinking water in the Netherlands? In this project various strategies to reduce the concentrations of OMPs are composed and scored by a Multi Criteria Analysis (MCA). The best strategy is tested on two case studies to see the influence of the strategy on the concentrations. The future situation regarding the emission of OMPs and discharge of river water is also taken into account. Whether the strategy is effective is determined based on limits of concentrations of OMPs. The scope of the project is on drinking water extraction areas in the Netherlands. Firstly a literature study on current European and Dutch legislation and policy, future trends regarding population growth, consumer behaviour and climate change and the presence and behaviour of target compounds in the water cycle is conducted. Based on the Deltascenarios two future scenarios regarding emission of OMPs, river discharge and precipitation are selected: REST and STEAM. Scenario REST is a scenario of economic stagnation with moderate climate change. In scenario STEAM both the economic situation and climate change increases. Later in the report these scenarios are used to test the best strategy on, which reduces the concentrations of OMPs in the water cycle. Dutch limits on OMPs in the water cycle only exist for a few compounds. For other compounds target values of other organisations are used. The found limits and target values are in the order of 0.1-1.0 ?g/L. The target compounds are selected based on an analysis of relevant compounds, which results in a limited number of compounds to elaborate on. Persistence of the compounds and availability of measurement data are important criteria in this analysis. The selected target compounds are carbamazepine, metformin, sulfamethoxazole (pharmaceuticals), iopromide (X-ray contrast agent), acesulfame-K, caffeine…

▼ Glaciers are known as climate indicators because of their sensitivity towards climatic perturbations and fluctuations. A majority of the world’s glaciers are currently melting as a response to climatic perturbations. Glaciers in Norway display the same pattern, and the loss of mass have accelerated during the 1990s to this day. The glaciers of interest in this paper is situated in a west to east transect with the maritime Ålfotbreen in the west, to the continental Gråsubreen in the east, with the intermediate Storbreen in between. Differences in the local climate have a significant impact on the future state of glaciers. This paper aims to compare the mass balance, mass turnover and mass balance sensitivity of the three glaciers of interest, between the years 1980 and 2018, to demonstrate the importance of the local climate and characteristics for glacial existence. Mass balance data series of each glaciers’ mass balance was analysed. In addition, development trends of the mean annual summer air temperature for respective glaciers’ region were also conducted. A literature review of relevant reports and publications will be presented and analysed to complement the result of this paper. The results of this paper indicate that the characteristics of respective glacier vary along the increasing continentality of the west to east transect, with the mass balance sensitivity decreasing from west to east. The mass turnover displayed varying patterns, between the years 1980 and 2018. ÅLF had the highest mass turnover for the period and GRÅ the smallest with STO in between. It can be concluded, based on the result of this paper, that the fate of glaciers depends on geographical location and local characteristics. The resemblance between Storbreen and Storglaciären, and the existence of Helagsglaciären who seem to survive against the odds, strengthens the importance of local characteristics.

▼ Taylor Glacier, an outlet of the East Antarctic Ice Sheet, flows through the Transantarctic Mountains and terminates in the Dry Valleys. Understanding how this glacier fluctuates is important for studies of glacial geology, paleoclimate, ice dynamics, and ecology. Sublimation is the primary mass-loss process for most of the glacier. Four years of specific balance measurements from the ablation zone show sublimation rates up to 40 cm per year. We used data from an array of weather stations as inputs to a model for latent heat flux and hence sublimation rate. Calculated and measured ablation rates agree to within uncertainties, indicating that wind speed and vapor pressure gradient (a function of temperature and humidity) are the governing variables, as expected from theory. Measurements and model results together allowed us to examine the spatial and temporal variations of sublimation on the glacier. On average, sublimation is about two times faster in summer than winter. Rapid sublimation occurs during storms and katabatic wind events, but such periods contribute less to the annual total than do slow, persistent losses. Spatially, sublimation reaches a maximum midway along the glacier, where descending surface air currents are focused by the topography of the aptly-named tributary, Windy Gully.

This thesis was carried as a collaboration of Delft University of Technology (TU Delft) and the companies Waternet and KWR. The main project aims to study the possibility of
thermal energy recovery from wastewater, reducing the carbon dioxide (CO2) emissions
linked to the energy sector. The present work is based on a previous computational model that was developed to simulate heat recovery from wastewater for constant flow rate and temperature of water.
The first goal is to simulate a wastewater discharge. In order to achieve this, a Gaussian function was added to the boundary conditions for water flow rate and water temperature.
As a second goal, this work aims to assess the significance of the terms present in the
water heat balance and air heat balance equations. Binary coefficients were added in each term of both equations and then all the combinations were computed.
The unsteady situation successfully simulated a main discharge and numerical predictions for water temperature and flow rate are presented. The deviations associated with the modified cases for the two equations suggest that the heat flux pipe to water (!!") and heat flux pipe to air (!!") terms are crucial for water and air heat balance predictions,respectively. In order to smooth extra oscillations, the time step (dt) was reduced and a smaller relative size of oscillations was obtained.
This work concludes with a section of future developments in order to improve the results
obtained. Despite of the fact that the current state of these routines does not allow us to accurately assess heat exchanges in pipes, promising results were obtained, proving that numerical modelling of heat recovery will contribute greatly to the development of the main project.

▼ The
mass balances of Brewster, Glenmary, Park Pass and Rolleston Glacier in the Southern Alps of New Zealand were investigated. To study the
mass balance, an integrative approach was chosen that included direct
mass balance measurements, aerial oblique end-of-summer snowline (EOSS) photos and a
mass balance model. The main focus was on the maritime Brewster Glacier where a field-based
mass balance programme was initiated with extensive direct measurements and installation of an automatic weather station (AWS). For the years 2005–2008, the net balances were 1141 mm water equivalent (mm w.e.), 282 mm w.e., 297 mm w.e. and -1653 mm w.e. with
mass balance gradients at the ELA ranging from 7 to 14 mm w.e./m. With the direct measurements, a
mass balance model of an intermediate complexity was calibrated. The model is based on a simple numerical
mass balance model that combines elements from energy-
balance and degree-day models and uses daily climate data as input. The three tested climate datasets were climate station data from the CliFlo database, an interpolated climate dataset from Andrew Tait and the ERA-40 reanalysis climate data. To downscale the climate datasets to the conditions at Brewster Glacier, the measured climate data from the Brewster AWS was used. After the model calibration the
mass balance was modelled for the past three decades. For the validation of the modelled
mass balance and snow cover, photographed EOSS, a geodetic survey and a parameterisation scheme were used. The EOSS records are from annual surveys that have been conducted since 1977 by taking oblique photographs of 50 index glaciers from a light aircraft. In the past, these records have been used as a proxy for the
mass balance under the assumption that the EOSS represents the equilibrium line altitude (ELA). Modelling the
mass balance for 30 years was difficult because of inhomogeneous climate data and almost non-existing high altitude climate data. However, the measurements, modelling results and the geodetic survey indicated that the
mass balance was positive from 1986–1997, negative from 1997–2007 and negative for the entire period from 1978–2007. The modelled and measured
mass balance also showed that the length of the ablation season varies remarkably in New Zealand. This highlighted the problematic use of the EOSS records as
mass balance proxy because the photographs are usually taken in early March which is sometimes well before the actual end of summer. Additionally, the ELA is defined from the
mass balance curve versus the altitude which is closely linked to the temperature, whereas the EOSS altitude is derived from the accumulation-area versus altitude distribution and in some cases from the size of snow patches. Limited
mass balance measurements were also taken on the transitional Glenmary Glacier and the maritime Park Pass and Rolleston Glacier. It was found that Glenmary and Park Pass Glacier were retreating and that Rolleston Glacier was stationary. At Glenmary Glacier, the
mass balance was strongly influenced by wind induced…

Ice Velocity and Mass Balance Study of the Skelton Glacier, Antarctica, Using Remote Sensing and GIS Techniques.

▼ The Skelton Glacier is one of the many smaller outlet glaciers located in the Transantarctic Mountains, where it drains ice into the Ross Ice Shelf. These outlet glaciers are important when determining the past, present, and future state of the mass balance of the East Antarctic Ice Sheet. This research uses satellite imagery acquired over a period of 15 years to obtain a high resolution velocity field for the Skelton Glacier which is then used to calculate the mass flux and mass balance at ten flux gates along the glacier using the input-output method. The high resolution velocity field is combined with ice thickness data and accumulation data from other sources to obtain the total mass balance.
The high resolution velocity field of the Skelton Glacier was created using European Remote-Sensing Satellite 1 and 2 (ERS-1/2) Synthetic Aperture Radar (SAR) data acquired in 1996 with the processing technique of SAR interferometry (InSAR). Because of the lack of differential InSAR pairs,
new auxiliary data from the ICESat and TanDEM-X mission were included into the analysis. A velocity field was created at a spatial resolution of 50m which was validated with in situ GPS measurements from 2011/12, and compared to lower resolution velocity fields of the Skelton Glacier. The ice velocity field is at improved accuracy for this area compared to previous studies and is thought to be representative for the mean ice velocity. The analysis of ice flux at several flux gates
allowed an improved error estimation of the applied technique to estimate the overall mass balance.
Mass flux estimates along the glacier were calculated using the new velocity field and additional thickness data, which was then compared to two accumulation datasets to give mass balance estimates along the glacier at selected flux gates. The mass flux through the grounding line was found to be 1.2165 Gt a⁻¹, which needs to be balanced in a state of mass balance equilibrium by a mean annual snow accumulation of about 185 mm a⁻¹ water equivalent over the total catchment area determined with 6569 km². The mass balance at the grounding line is slightly negative, but the second flux gate is thought to be more representative of the mass balance, which is estimated to be 0.0441 Gt a⁻¹. Error
analysis of the mass balance estimates found uncertainties in this data to be approximately 0.110 Gt a⁻¹. It is concluded from the analysis that further improvements in the overall mass balance estimate can be primarily obtained by a better knowledge of ice thickness and snow accumulation.

▼ Mechanical agitation is used commonly in gas-liquid reactors to improve the homogeneity of dispersion and to enhance the transfer of reacting compounds between gas and liquid. The design and scaleup of gas-liquid reactors is problematic due to non-ideal mixing, heat and
mass transfer limitations. In this work, phenomenological models were developed and validated against experiments to investigate local gas-liquid
mass transfer in agitated tanks. The aim was to develop more generalized and reliable simulation tools for agitated gas-liquid reactors. Gas-liquid hydrodynamics and
mass transfer are related complicatedly to bubble size. Local Bubble Size Distributions (BSD) were measured from several systems in agitated laboratory tanks. The measurements revealed a wide range of existing bubble sizes and a significant spatial inhomogeneity of BSDs. The comparison between capillary suction probe, phase Doppler anemometry and photography showed that BSDs are biased due to limitations of experimental techniques. A dynamic multiblock model with a limited number of ideally mixed subregions was developed to investigate the inhomogeneity of dispersion.
Mass transfer fluxes were modelled based on the two-film theory and simplified solution of Maxwell-Stefan diffusion. Local BSDs and
mass transfer areas were solved from the population balances for bubbles by the method of classes. Unknown parameters in phenomenological bubble breakage, coalescence, turbulent slip and
mass transfer models were fitted against experiments. The multiblock model was used to describe macroscopic inhomogeneities of dispersion in the fitting. The results show that multiblock stirred tank model is an excellent tool for the testing and validation of closure models. The adjusted models describe local BSDs, gas holdups and
mass transfer rates under varying agitation conditions and physical properties of dispersion in a limited range. Due to complexity of gas-liquid agitation measured local BSDs alone are not however sufficient for the validation of mechanistic closure models. More basic research and isolated experiments are needed for this. A comparison between multiblock and CFD simulations shows that multiblock model is an optimal trade-off between the accuracy and CPU time, when local
mass transfer rates are of interest. The simulations with the validated models predict a significant inhomogeneity of
mass transfer, which mostly results from the spatially varying gas-liquid interfacial areas. The developed models relate
mass transfer to local physical properties and micro-scale turbulence. They are less dependent on vessel size and geometry than traditional kLa-correlations and therefore suitable for detailed reactor scale-up and design studies. The validated population
balance and
mass transfer closures for aqueous xanthan systems together with the bioreaction kinetics from literature were incorporated to multiblock fermenter model to investigate batch xanthan fermentation. The simulations show the need of population balances for the detailed…

▼ Totten Glacier, East Antarctica, a glacier that holds a 3.9 m sea level change equivalent, has thinned and lost mass for decades. Change in surface elevation calculated from high- resolution DEM differencing shows significant surface lowering rates concentrated in areas of fast flow, hence is probably of dynamic origin. A 26-year long ice velocity time series (1989-2015) consisting of 13 maps is developed from Landsat and interferometric synthetic aperture radar (InSAR) data. We find significant speed-up in ice velocity, especially in 2002-2007, followed by a period of slow decrease in 2010-2014. Comparing the ice discharge with surface mass balance suggests that the glacier mass balance was already negative in 1996 and became more negative into the 2000s. Grounding line mapping using differential InSAR, combined with high resolution topographies of the ice surface and ice draft, reveals a 1,500-2,300 m deep grounding zone. The grounding line extends 15 km inland along two prominent side lobes. Immediately upstream of the grounding line, there is an ice plain which is slightly grounded, only 15-50 m above hydrostatic equilibrium. At the glacier center, we detect a retreat of the grounding line up to 2.6±0.1 km by comparing differential InSAR data acquired 17 years apart. The retreat is asymmetrical along the two lobes, but consistently indicates a total thinning of 11.9±1.5 m from 1996 to 2013. On the ice plain, the glacier is prone to rapid retreat around a region about 7 km long, but inland the bed elevation rises. Sustained thinning will cause further retreat and speed up, but will not be conducive to a marine ice sheet instability. The ultimate cause of the changes is not known, but probably of oceanic origin. Comparison of the velocity time series and reanalysis sub-surface ocean temperatures indicates that Totten Glacier may be very sensitive to oceanic perturbations.

▼ Glaciers are the essential source of fresh water not only to human sustenance, but it is also vital for all lifeforms on earth. Glaciers are also key components in understanding rapid changes in climate. This makes understanding of glacier
mass, extent, and overall state essential. In this dissertation, the objective was to analyze the state of snow and ice masses in the mid (California) and low latitude (Chile/Argentina) western American regions using geospatial technology. This study also analyzed the effects of anomalies in snow
mass on the regional agricultural practices in Californias Central Valley.
In the Southern Andes, the digital elevation models from Shuttle Radar Topographic Mission (SRTM) (the year 2000) were compared with the elevation footprints from the Geoscience Laser Altimeter System (GLAS) campaign for the years 2004 through 2008. Generally, in all sub-regions, the elevation values were lower than the elevation for the year 2000, which demarcates continuous recession of ice
mass in the Andean region. Also, this study quantified snow cover extent and
mass balance variation in the Sierra Nevada and Mt. Shasta regions in California. To unearth anomalies in snow
mass, study used digital elevation models generated from the Advanced Spaceborne Thermal
Emission and Reflection Radiometer (ASTER) between the year 2000 and 2015. A remarkable reduction in snow cover extent of about 80% was observed in the studied watersheds of California. Lastly, the impacts of snow
mass anomalies on the total water storage (TWS) and agriculture land cover in the Californias Central Valley were quantified and geo-visualized. The study noticed the change in the land cover area of about 20% (6993 sq.km) due to the alteration of Agriculture land to impervious land covers. Most of the change in the agriculture land cover of about 4402 sq.km occurred in the San Joaquin and Tulare Basins of southern Central Valley region.
This dissertation concludes that the increased temperature in the Andes and California has adversely impacted Cryosphere components in the region in the past decade. Besides, it provides valuable insights into the changing state of cryosphere components and highlights impacts of anomalies in TWS on a billion-dollar agricultural industry.

▼ Canadian High Arctic terrestrial ice masses and the
polar atmosphere evolve co-dependently, and interactions between
the two systems can lead to feedbacks, positive and negative. The
two primary positive cryosphere-atmosphere feedbacks are: 1) The
snow/ice-albedo feedback (where area changes in snow and/or ice
cause changes in surface albedo and surface air temperatures,
leading to further area changes in snow/ice); and 2) The elevation
- mass balance feedback (where thickness changes in terrestrial ice
masses cause changes to atmospheric circulation and precipitation
patterns, leading to further ice thickness changes). In this
thesis, numerical experiments are performed to: 1) quantify the
magnitudes of the two feedbacks for chosen Canadian High Arctic
terrestrial ice masses; and 2) to examine the direct and indirect
consequences of surface air temperature changes upon englacial
temperatures with implications for ice flow, mass flux divergence,
and topographic evolution. Model results show that: a) for John
Evans Glacier, Ellesmere Island, the magnitude of the terrestrial
snow/ice-albedo feedback can locally exceed that of sea ice on less
than decadal timescales, with implications for glacier response
times to climate perturbations; b) although historical air
temperature changes might be the direct cause of measured englacial
temperature anomalies in various glacier and ice cap accumulation
zones, they can also be the indirect cause of their enhanced
diffusive loss; c) while the direct result of past air temperature
changes has been to cool the interior of John Evans Glacier, and
its bed, the indirect result has been to create and maintain warm
(pressure melting point) basal temperatures in the ablation zone;
and d) for Devon Ice Cap, observed mass gains in the northwest
sector of the ice cap would be smaller without orographic
precipitation and the mass balance – elevation feedback, supporting
the hypothesis that this feedback is playing a role in the
evolution of the ice cap.
