Storm Water General Industrial Permit Non-Filers Identification and Outreach
Storm water discharges convey pollutants from urban activities that can impair surface water quality. Industrial facilities have been identified as one source of storm water pollutants...

Economic Efficiency of Regulations for Allocation and Control of Surface Water Withdrawals in Humid Regions
This paper proposes several alternative regulatory instruments for the allocation of flowing water and evaluates these instruments with respect to economic efficiency for a hypothetical...

Modeling 3D Free Surface Flow in Compound Channels: A Validation Case Study
This paper presents the results of a validation study of a free-surface flow model. For the validation, experimental data collected in a compound open channel is used. This validation...

Modeling the Impact of Uncertainty in Spatial Variability of Estuarine Boundary Conditions
Multi-dimensional numerical estuarine models that consider baroclinic forcing require the specification of both the water surface and the water density (salinity and temperature) at the...

Automated Tools for Spatially Distributed Rainfall/Runoff Modeling
A watershed modeling system (WMS) has been developed to address the needs of surface water rainfall/runoff computer simulations. WMS, developed at the Engineering Computer Graphics Laboratory...

A New Model of California's SWP/CVP Systems
A water allocation reservoir simulation model is combined with a ground water-surface water simulation model resulting in an integrated model for use in water resource planning studies...

Modeling of Surface Water Pumps in TVA Reservoirs
This paper describes the numerical simulation of surface water pump perforniance at Cherokee and Douglas Dams. The modeling objective was to determine the surface water pump initial velocities...

Optimization Modeling of Complex Surface Water Collection Systems
The New York City (NYC) water supply system is currently being modeled using Linear Programming (LP) optimization techniques. A series of simulations were performed to investigate the...

Flood Damage Estimates Using GIS Spatial Analysis
The catastrophic flooding in the midwest during the Summer of 1993 and in California in the Spring of 1995 resulted in flood damage estimates in the hundreds of millions to billions of...

Verification of a 3D Flow Model Using Laboratory Data
The ASCE Task Sub-Committee on 3D Free Surface Flow Model Veri fications has been developing test cases and/or procedures for both computational model developers and users over the past...

The Effects of Water Surface Profiles on Manning's Roughness Coefficient
The Manning Equation has wide application in engineering practice. Nonetheless, certain aspects of it are still not widely understood. Often, engineers deduce the value of Manning's...

The Use of an Equivalent Porosity Method to Model Flow in Marshes
Two dimensional modeling of marshes under unsteady flow conditions often involves description of sections that alternately wet and dry. The equivalent porosity method (King and Roig, 1988;...

Stochastic Determination of Wave Heights for Flood Control Channels
Physical model data for subcritical and supercritical flow has been collected and analyzed to determine a statistically-based relationship for wave runup heights in a trapezoidal channel....
