Comparison of Near-Field Dilutions Derived from In Situ Measurements and Simulated Dilutions at the Sand Island Sewage Outfall Plume, HI
Near-field dilutions of the Sand Island Treatment Plant (SITP) wastewater plume were derived from salinity measurements made at the sewage outfall between Sept. 25?Oct. 1, 1994, a period...
Irrigation of Grain Sorghum on the Delmarva Peninsula
Irrigated grain sorghum experiments were conducted for two years on a Norfolk sandy loam soil. Full irrigation was compared to partial irrigation and no irrigation in a randomized block...
Regional Economic Impacts of a Land Fallowing Program?The Palo Verde Test Land Fallowing Program Case Study
The Metropolitan Water District of Southern California (MWD) and the Palo Verde Irrigation District (PVID) implemented a two-year test land fallowing program (Program) from August 1, 1992...
Laboratory Evaluation of a Conductivity Probe for Scour Monitoring
Laboratory tests were used to evaluate the ability of conductivity sensors to measure streambed elevation. Tests were completed on a 2.1-m probe with a resolution of about 8 cm that was...
Evaluation of Selected Instruments for Monitoring Scour at Bridges in New York
Reliable methods to monitor scour at bridges are needed to ensure public safety and minimize the cost to repair or replace vulnerable bridges. The U.S. Geological Survey, in cooperation...
Sedimentation Dynamics of Tidal Inlets
Tidal inlets are very dynamic systems subject to continuous morphological changes under the action of tides, waves and transported sediments. Although flow and sediment dynamics are interactive,...
Creeping Suspicion
High-capacity, epoxy-coated anchors were installed at Upper Occoquan Dam to increase the stability of the 70-foot-high concrete gravity dam and powerhouse under revised Probable Maximum...
