Channel Junction Effects in Channel Network Flow Simulation
In this paper, the momentum equations, which are applicable at channel junctions, are suggested based on the conservation of momentum flux. In the equation, the lateral inflow angles are...
Modeling the Ecological Impacts of Flaming Gorge Dam Operations
Hydropower operations at Flaming Gorge Dam on the Green River in Utah, U.S.A., can produce rapid downstream changes in flow and stage during a day. These changes can, in turn, affect ecological...
Inundation Studies in Case of Failure of King Talal Dam
In this paper a brief description of the studies is presented and the computed results are summarized. During running the program, several difficulties were encountered. These problems...
Optimization and Simulation in Design and Operation of Reservoirs
Due to stochastic nature of rivers, their volumetric yields are random variables. Spatial and temporal redistribution of Water makes the reservoir construction a must. Therefore, water...
Optimum Storage Reallocation and Gate Operation in Multipurpose Reservoirs
This research is intended to integrate long term operation rules and real time operation policy for conservation and flood control in a reservoir, the familiar yield model has been modified...
Multiobjective Optimization of Multireservoir System
In the present study, a detailed multiobjective nonlinear programming model is formulated and applied to a multireservoir system at upper reaches of Krishna river basin in Karnataka State,...
Alachlor Transport in Laboratory Soil Columns
Spraying of agricultural chemicals result in their travel downward through the unsaturated zone and adsorption to the surrounding soil. Infiltration from rainfall and irrigation solubilize...
Predicting Transport of Organics through Soil Columns using Distributed Mass-Transfer Rates
A numerical model to describe contaminant transport through soil columns, including distributed mass-transfer, is developed. Both a gamma distribution and a lognormal distribution are...
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...
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...
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...
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...
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-,...
