Small-Scale Catchment Analysis Of Water Stress In Wet Regions Of The U.S.: An Example From Louisiana, Hisham Eldardiry, Emad H. Habib, David M. Borrok
Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works
Groundwater is increasingly being overdrafted in the Southeastern U.S., despite abundant rainfall and the apparent availability of surface water. Using the state of Louisiana as an example, the current study quantifies the stresses on water resources and investigates the potential for opportunities to use surface water in lieu of groundwater pumping. The assessment is based on a fine watershed scale (12-digit Hydrological Unit Code [HUC] boundaries) water balance between the availability of surface and groundwater and surface water and groundwater demand. Water demand includes environmental flows, as well as public supply, rural domestic, industrial, power generation, agricultural, and aquaculture sectors. …
Water-Rock Interactions And Seasonal Hydrologic Processes In Constructed Everglades Tree Islands, Andres E. Prieto Estrada
Water-Rock Interactions And Seasonal Hydrologic Processes In Constructed Everglades Tree Islands, Andres E. Prieto Estrada
FIU Electronic Theses and Dissertations
The decline of tree islands in the freshwater-Everglades wetland because of hydrologic manipulation, has compromised valuable ecosystem services. Although the role of tree islands in maintaining freshwater quality stems largely from evapotranspiration processes, fundamental questions remain about the effects of different geologic materials on their hydrogeochemical functioning. To reduce this uncertainty, the lithological composition of a set of man-made tree islands was investigated coupled with long-term hydrologic and hydrochemical data. Key results indicate that limestone substrates and peat substrates with elevated proportions of sand, facilitated surface water-groundwater interactions and mineral dissolution. However, limestone-based islands were more effective in lowering the …
Evaluating The Influences Of Karst Hydrogeology On Freshwater Harmful Algal Blooms In Kentucky Lakes, Robert T. Schaefer
Evaluating The Influences Of Karst Hydrogeology On Freshwater Harmful Algal Blooms In Kentucky Lakes, Robert T. Schaefer
Masters Theses & Specialist Projects
A problem exists in Nolin River Lake and Rough River Lake in Kentucky, due to the increasing prevalence of cyanobacterial-based harmful algal blooms (CyanoHABs) and the threats they pose to local communities. These lakes were developed as artificial reservoirs from embankment. Further complicating the issue, the lakes are located within a heavily karstified region and there exists no plan or method currently for monitoring or managing CyanoHABs in a karst region with regard to groundwater inputs to the lake systems or their tributaries. A mixture of techniques and analysis methods was used to determine the best way to monitor and …
Comparison Of The Chemical And Isotopic Composition Of Groundwater And Surface Water In The South Sound Region, Andrew H. Oberhelman
Comparison Of The Chemical And Isotopic Composition Of Groundwater And Surface Water In The South Sound Region, Andrew H. Oberhelman
Summer Research
This project seeks to characterize the chemical and isotopic compositions of groundwater and surface water in portions of Pierce and King Counties, with the goal of using these results to determine the water sources of local lakes. Specifically of interest are lakes studied by Puget Sound students over the past ~10 years where water analyses appear to define a mixing line, likely between surface runoff and the shallow groundwater (Figures 1, 2, and 3). Existing data pertain only to surface water from the lakes while data pertaining to groundwater is patchy or nonexistent and includes only a few of the …
