Hydrogeological Conceptual Model Of La Villa River Watershed, Republic Of Panama, Maria G. Castrellon Romero

Honors Scholar Theses

Groundwater in Panama is a valuable and poorly understood resource. Its exploitation has increased 75% in the past decade, reaching a total value of 700,000 m³/day or 185 million gallons per day (MGD). Climate change has caused a lengthening of the dry season, which has reduced precipitation and streamflow, resulting in surface water scarcity during this period. Nevertheless, it has not been possible to determine the extent to which groundwater sources have been affected by these factors since systematic monitoring of groundwater levels has not been implemented in Panama. With support from National Institution of Drinking Water Supply …

Development Of An Approach To Evaluate Fractured Crystalline Bedrock Water Resource Supply And Sustainability, Helen E. Spera

Master's Theses

Groundwater derived from fractured crystalline bedrock is an important resource in Connecticut. Despite its importance we know very little about this resource. This study was conducted at the Plant Science and Landscape Architecture Research and Education Facility, University of Connecticut, Storrs, CT. The objectives of this study were: to improve the characterization of the hydrogeology of the facility; to develop a method to determine the amount of recharge to the bedrock from the overburden during pumping and non-pumping periods; and to develop an approach that can be used in evaluating the sustainability and zone of contribution of bedrock pumping wells. …

Model Based Assessment Of Potential Impacts Of Climate Change On The Flow Of The Main Headwaters Of The Nile River: Equatorial Lakes Region And Blue Nile Basins, Fisseha G. Berhane

Master's Theses

Berhane Fisseha. Model based assessment of potential impacts of climate change on the flow of the main headwaters of the Nile River: Equatorial Lakes Region and Blue Nile basins (Under the direction of Dr. Richard Anyah).

Spatially and temporally detailed assessment of the hydrologic processes of the main sources of the Nile River headwaters (Blue Nile basin and Equatorial Lakes Region) is vital for basin-wide scale management to cope with the pressing water problems due to burgeoning populations, a growing demand for electricity, irrigation for food production and possible climate change.

The main objectives of this study were to use …

The River Discontinuum: Applying Beaver Modifications To Baseline Conditions For Restoration Of Forested Headwaters, Denise Burchsted, Melinda Daniels, Robert Thorson, Jason Vokoun

Center for Integrative Geosciences

Billions of dollars are being spent in the United States to restore rivers to a desired, yet often unknown, reference condition. In lieu of a known reference, practitioners typically assume the paradigm of a connected watercourse. Geological and ecological processes, however, create patchy and discontinuous fluvial systems. One of these processes, dam building by North American beavers (Castor canadensis), generated discontinuities throughout precolonial river systems of northern North America. Under modern conditions, beaver dams create dynamic sequences of ponds and wet meadows among free-flowing segments. One beaver impoundment alone can exceed 1000 meters along the river, flood the valley laterally, …
