A Demonstration of Strobe Lights to Repel Fish
An EPRI review (EPRI, 1986) of fish protection systems for hydroelectric facilities identified strobe lights as a potential behavioral system to minimize fish entrainment. In 1988, EPRI...
Sediment Removal from Sand Hills Aqua Farms Using a Sediment Evacuation Pipeline System
Reservoir sedimentation continues to deplete the world's reservoirs of valuable storage capacity. Several reservoir sediment removal techniques have been successful in regaining...
Development of Hanford Site Lysimeter Facilities
Lysimeters have been constructed at the Hanford Site near Richland, Washington to quantify mechanisms that affect migration of radioactive and hazardous waste in geologic media. The history...
Water Balance Lysimetry at a Nuclear Waste Site
Lysimeters measure effects of soil, vegetation, and climate on water balance and groundwater recharge at a nuclear-waste site in arid-southcentral Washington State, USA. Data from 4 lysimeter...
Small Lysimeters for Documenting Arid Site Water Balance
Small weighing lysimeters consisting of plastic pipes with lifting and drainage fittings were installed at the arid U.S. Department of Energy (DOE) Hanford Site in southcentral Washington...
Use of Lysimeters for Determining Characteristics of Pore Water
Lysimeters have been installed and used during the cleanup and stabilization of several former uranium processing sites in the western United States. In particular lysimeters have been...
