Dissertations, Master's Theses and Master's Reports
An analysis of the effects of the Land Use Land Cover (LULC) change and its impacts on the hydrological cycle of tropical montane catchments influenced by cloud forest (TMCF) is developed in Central Veracruz, Mexico. This work started with the analysis of data from monitored-micro-catchments with contrasting LULC. Later the suitability of an improved version of the Soil and Water Assessment Tool model for the Tropics (SWAT-T) was evaluated. Finally, potential future land use scenarios, including conservation targeting alternatives were evaluated using a calibrated Seasonal Water Yield model as part of the Integrated Valuation of Ecosystem Services and Tradeoffs framework …

Quantifying Water Recharge And Water Use In Hand Dug Wells: A Case Study Of Thiawor, Senegal, West Africa, Celine Carus

For many rural communities in Senegal, water is an essential life-giving need received only through a network of hand dug wells. Increasing rainfall variability in the Sahel has driven greater water insecurity for those communities that rely on rain-irrigated systems for agriculture. This study investigates the retrieval, purposes, and quantities of seasonal water usage on a small domestic scale, as well as an analysis of perceived water availability in the wells during the rainy season. Additionally, using a combination of interview data and pumping test data obtained from the village wells, water usage and estimated daily needs are calculated and …
Dissolved Organic Matter Movement Across Lake Superior’S Terrestrial-Stream-Coastal Interface, Karl M. Meingast
Dissolved Organic Matter Movement Across Lake Superior’S Terrestrial-Stream-Coastal Interface, Karl M. Meingast
Dissertations, Master's Theses and Master's Reports
Dissolved organic matter (DOM) represents a carbon pool that can be easily translocated between ecosystems with the movement of water. This study examines the controls on DOM quantity and character delivered to Lake Superior primarily during the snowmelt period. We employed long-term stream dissolved organic carbon (DOC) data to determine quantity as well as absorption and fluorescence spectroscopy to analyze DOM structure. Our results indicate that an increasing trend in DOC concentrations, likely driven by decreases in acidity of precipitation, combined with slightly less annual runoff have resulted in relatively constant fluxes of DOM to Lake Superior. Additionally, our study …
