Evaluating Climate Change Effects In Two Contrasting Reservoirs Using Two-Dimensional Water Quality And Hydrodynamic Models, Oliver Obregon

Theses and Dissertations

I analyzed and compared impacts from global climate change (GCC) and land use change to Deer Creek (United States) a temperate reservoir and Aguamilpa (Mexico), a tropical reservoir by using calibrated CE-QUAL-W2 (W2) water quality and hydrodynamic models based on field data over an extended time period. I evaluated and compared the sensitivity to predicted GCC and land use changes. I individually evaluated changes to air temperature (TAIR), inflow rates (Q), and nutrient loads (PO4-P and NO3-NO2-N) followed by analysis of worst case scenarios. I developed analysis methods using indexes to represent the total …

Developing Methods To Assess The Potential Effects Of Global Climate Change On Deer Creek Reservoir Using Water Quality Modeling, Reed Earl Chilton

Theses and Dissertations

To evaluate the potential impacts of future climate change on a temperate reservoir, I used a calibrated water quality and hydrodynamic model validated using three years of data (2007-2009) from Deer Creek Reservoir (Utah). I evaluated the changes due to altered air temperatures, inflow rates, and nutrient loads that might occur under Global Climate Change (GCC). I developed methods to study GCC on reservoirs. I produced Average Water Temperature Plots, Stratification Plots, and Total Concentration Plots. Average Water Temperature Plots show the sensitivity of the water temperature to various parameters. Stratification Plots quantify stratification length and strength as well as …

Using Space Borne Microwave Sensors To Track Large Antarctic Icebergs, Jarom James Ballantyne

Theses and Dissertations

Studying Antarctic icebergs can provide insight into climatic changes of the Earth's frozen continent. Antarctic icebergs are regularly formed by the separations of massive sections of ice from ice shelves and glaciers.

The National Ice Center (NIC) is playing a major role in sea ice analysis and forecasts. As a part of its mission the NIC is using a variety of satellite sensors to track many large Antarctic icebergs. The NIC reports iceberg positions every 15-20 days. However, there are limitations in the NIC's iceberg tracking techniques. The areas covered by the images used by the NIC are limited to …
