Picacho Reservoir Enhancement Study for Water Recharge, Reparian Enhancement, and Water-Based Recreation Purposes
This study was conducted for the Pinal County Department of Civil Works in Florence, Arizona. It investigated the feasibility of a major enhancement and expansion of Picacho Reservoir,...
Vegetative Roughness in Flood Control Channels
Laboratory flume tests and field evaluations were undertaken as a part of the Flood Control Channels Research Program to determine hydraulic roughness values for various types of floodplain...
Hydraulic Effects of Habitat Structures in Flood Control Channels
Three field sites have been established and laboratory flume experiments begun to assess the effect of habitat enhancement measures on water-surface profiles and local scour in flood control...
Using HEC-RAS to Compute Scour at Bridges
HEC-RAS (River Analysis System) is an integrated system of software, designed for interactive use in a multi-tasking environment. The system is comprised of a graphical user interface...
New Block Copolymers for Membrane Materials
New fluorine containing polymer materials, which contain n-fluoro octylacrylate (pFOA) or n-fluorooctylmethylacrylate (pFOMA) repeating units, are being explored for use in thin film composite...
California's Visions of Groundwater: A Water Source and a Salt Sink
Public interest in groundwater resources can be expected to increase. There are few alternative, undeveloped, surface water resources to meet increasing water demand for municipalities....
Evaluation of Potential Impacts to Endangered Species that Use Wetland Areas: A Case Study
A proposed runway extension in an airport adjacent to a large riverine system and containing a small perennial branch of the riverine system would result in loss and modification of forested...
Artificial Recharge in the Oakes Test Area
The Oakes Test Area (OTA) was developed to evaluate predicted impacts of developing irrigation in the Garrison Diversion Unit in North Dakota. A limited irrigation water supply has forced...
Small Inocula Can Effect
This is the first report of colonization of soil by small numbers of a genetically engineered microorganism. The study suggests that the addition of small inocula of D5 to contaminated...
Design and Implementation of On-Farm Surface Drainage Projects in the Humid Tropics of Mexico
In the humid tropics of southeastern Mexico, the Mexican National Water Commission (CNA) has constructed a network of collector drains for stormwater runoff removal. At the same time the...
Assessment of the Surface-Water Pollution and Measures for Emergency Stations Warning in the Republic of Uzbekistan
In the Republic of Uzbekistan, a special system operates that is designed for the observations on the quality and ecological state of the river ecosystems including: 1-hydrochemical control...
Effects of Spatial Data Resolution and Subarea Size on a Distributed Runoff Model
Spatial data layers of elevation, land use, and soils for a small agricultural watershed in Pennsylvania were used to study the effect of resolution degradation of raster data on the output...
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...
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...
Immobilization of Metals and Solids Transported in Urban Pavement Runoff
Urban areas in North America continue to grow in size and population. With this growth is an increase in automotive traffic, roadway pavement and deleterious anthropogenic constituents....
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...
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...
Eastern San Joaquin County Groundwater Resource Planning Model Development and Calibration
An Integrated Groundwater Surface Water Model (IGSM) has been developed for the Eastern San Joaquin County in the Central Valley of California to evaluate the future water resources management...
