Rainfall-Runoff Modeling for Watershed Stormwater Management
In the design of watershed stormwater management plans used for land development, the Pennsylvania State Runoff Model (PSRM) presents upstream subbasin flows that contribute to the peak...
Development of the San Joaquin County Hydrology Manual
A hydrology manual was prepared for the County of San Joaquin, California for the determination of storm runoff quantities for the design of flood management facilities, floodplain analysis,...
Sediment Impacts on Yield from a Two-Reservoir System in Puerto Rico
The Dos Bocas and Caonillas reservoirs in Puerto Rico are being considered for conversion from hydroelectric to water supply operation. Both reservoirs are approximately 50 years old and...
Integrated Hydrological/Ecological/Economic Modeling for Examining the Vulnerability of Water Resources to Climate Change
A methodology for assessing regional-scale hydrologic vulnerability to climate variability which incorporates ecologic and economic factors is presented. A simple economic model of damages...
Expected Moments Alogrithms for Flood Frequency Analysis
The Expected Moments Algorithm (EMA) is a new but conceptually simple approach for the treatment of nontraditional data in flood frequency analysis. Nontraditional data includes censored...
Discussions of a 3D Numerical Simulation of Transient Regional Groundwater Flow and Transport
A 3D numerical model of a groundwater flow and transport was developed to study the movement of radionuclides in the Savannah River Nuclear Site, South Carolina. The modeling effort has...
Effects of Ignoring Well Losses on the Specific Capacity Function
This paper combines these equations with the traditional step-drawdown equation to generate a more realistic relationship among discharge, specific capacity, and drawdown. Under both confined...
Organizing a Local Water Resources Technical Group
Participating in a local water resource technical group can be rewarding professionally as well as socially. However, if such a group does not exist in your area, organizing one is an...
The Birth and Success of Orange County's Hydrology and Hydraulics Technical Group
The Orange County.s Hydrology and Hydraulics Technical Group (HHTG) has been very successful ever since it was founded in 1991. The HHTG is incorporated as a Technical Group under the...
Searching for Optimal Combinations of Stormwater Detention Basins
Hydrology of urban areas is dominated by two distinct characteristics: (1) a preponderance of impervious surfaces created primarily by pavement and roofs, and (2) the presence of constructed...
Ponding Study of January 1993 Storm Event within Airport Industrial Park, Oceanside, California
A water ponding study was conducted to investigate flooding that occurred during the January 16, 1993 storm event (the event) in the Oceanside Airport Industrial Park (the Park), located...
Calibration of Sediment Transport Model for the Upper End of Elephant Butte Reservoir
Elephant Butte Reservoir is located about 125 miles north of El Paso, Texas on the Rio Grande. The reservoir is approximately 35 miles long with a narrow neck, called the Narrows, about...
Computing Flood Damage Reduction Accomplishment
Following flood events, the damage reduced by a federal flood damage reduction project must be computed to inform the public and assist officials in making decisions. This paper will describe...
Mitigation of Flood Hazard on Alluvial Fans
A number of investigators have suggested that the limits of the traditional, stochastic, one-dimensional model of alluvial fan flooding have been reached and that there are one- and two-dimensional...
Cropping Systems on the Delmarva Peninsula to Reduce Ground Water Contamination
A total of twelve cropping systems were simulated with the GLEAMS model for nitrate leaching. A precipitation model was developed using a Markov chain model and a gamma distribution for...
Risk-Based Planning and Management of Maintenance Dredging
The U.S. Army Corps of Engineers (Corps) Institute for Water Resources (IWR) is developing and applying a risk-based approach to address maintenance dredging cost, reliability, and budgetary...
Water Quality Modeling of the Rouge River Watershed
A relatively detailed modeling framework for calculating pollution flows and loads to the Rouge River has been developed and tested successfully. The framework includes consideration of...
Numerical Modeling of Water Flow over Porous Media
The momentum transport phenomena at the interface of porous media and fluid are numerically investigated. The single domain approach is used with matching boundary conditions; i.e., the...
Sediment Removal from Stormwater Runoff
Sediment traps, also known as baffle boxes, are being used throughout the state of Florida to remove sediment from stomiwater. A baffle box is divided into three compartments by two bathers,...
Interdisciplinary Research of Mountainous Areas: Past, Present, and Future
In the past few years, there has been a growing recognition internationally, of a need to better understand hydrometeorologic, hydraulic, sedimentologic, geomorphic processes in gravel-,...
