Third Lake Watershed Assessment and Action Plan
Third Lake, located in Lake County, Illinois, is expected to exhibit worsening inlake water quality as development occurs within its watershed. A geographic information system (GIS) application...
Regional Optimization of Non-Point Source Load Reduction
The paper reports the results of a study to develop a regional optimization model to determine pollutant load reduction strategies for Tampa Bay. The study aims to determine cost-effective...
Groundwater Remediation at a Superfund Site
Soil and groundwater contamination at the Montana Post & Pole site in Butte, Montana, one of the nation's oldest Superfund sites, has developed into one of the most significant...
Fate/Transport Modeling and Remediation of Contaminated Plume at Vance Airforce Base
Air Training Command (ATC) at Vance Air Force Base (VAFB) is responsible for implementing the Installation Restoration Program (IRP) according to the Comprehensive Environmental Response,...
Threshold Precipitation Events and Groundwater Recharge
Data from two study sites on the Nevada Test Site, Nevada are used with precipitation data from other long-term precipitation gages to identify the frequency of precipitation events that...
Effect of Data Sampling Time Resolution on Probability Distribution of Elapsed Time Between Rainfalls
The elapsed time between rainfalls is useful information in statistical forecasting of rainfall and runoff. The probability density function (pdf) of the elapsed time can be determined...
Flood Monitoring Network In Southeastern Louisiana
A flood monitoring network has been established to alert emergency operations personnel and the public about hydrologic conditions in the Amite River Basin. The U.S. Geological Survey...
Riparian Wetlands and Flood Stages
The paper studies concurrent flood stage records from two fourth-order streams in the hills of northwest Mississippi with similar soils, watershed relief and overall land use. The streams...
Mathematical Models to Assess Stream Dynamics
A methodology is proposed to predict the behavior of meandering streams. Using a stream-shift model, lateral channel shift over a period of time is computed for several reaches with the...
Revised Hydraulic Design of the Rio Hondo Flood Control Channel
The US Army Engineer District, Los Angeles has completed a major review study of the Los Angeles County Drainage Area (US Army, 1992) and has determined that the existing flood control...
Instream and Streambank Environmental Feature Guidelines
Tightened regulatory requirements and a renewed appreciation for the benefits of preserving our diminishing natural resources have led to a recent profusion of stream restoration projects...
Fish Entrainment and Strategies for Diversion
Hydroelectric power projects often impound reservoirs which contain important recreational fisheries. The entrainment of fish through these facilities and the possible associated entrainment...
West Columbus, OH LPP Gate Closure Analysis - A Study of the Requirements for Multiple Closures
Providing flood protection by levees and/or floodwalls often requires the use of temporary closures, in lieu of the more expensive relocation of highways and railroads, in order to maintain...
Hydro Plant Research Data Acquisition System
The Colton Hydroelectric Development, located on the Raquette River in the northwestern part of New York State, is the site of a two year research project to test the use of heated trashracks...
Use of a Modified Hybrid Model to Analyze the Effectiveness of Jetties in Reducing Marina Sedimentation
The effectiveness of the construction of jetties near the entrance channel of a coastal marina in reducing marina sedimentation has been analyzed using a modified hybrid model. The modified...
Unsteady Spillway Inlet Conditions at the Weatherford Water Supply Reservoir
The Weatherford Water Supply Reservoir, in Weatherford, Texas has had frequent lake-side flooding and has experienced unstable spillway operation. Residents complained that the water had...
Stratified Flow in an Impounded Inland River
Stratified flow in the Seneca River of central New York is described. This flow condition occurs in the vicinity of the outflow from saline Onondaga Lake, and exists both upstream and...
Verification of a Three-Dimensional Model of Delaware Bay
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...
Use of FESWMS-2DH for the Attaway Road Bridge Repair Project
The paper presents the application of the Finite Element Surface Modeling System: Two Dimensional Flow in a Horizontal Plane (FESEMS-2DH) computer program in the Attaway road bridge repair...
A Three-Dimensional Numerical Simulation of Seasonal Flow and Salt Transport in the C&D Canal
Two seasonal-scale, three-dimensional hydrodynamic models with salt transport using CH3D-WES were constructed to represent the most critical periods of environmental concern: fishery spawning...
