Santa Ana River Salt Marsh Restoration: Orange County, California, U.S.A.
As part of the All-River Plan of the Santa Aria River, the 92 acre Santa Ana River Marsh (Marsh) was constructed at the Pacific Ocean outlet in Orange County, California. This project...

Drop Structures in the Real World: Guidelines for Drop Structures in Grass Lined and Wetlands Channels

Comparison of Stochastic Programming and Robust Optimization Models for Groundwater Plume Containment
Stochastic optimization models for containing a groundwater contaminant plume through the installation and operation of pumping wells are developed. Two related formulations are presented—stochastic...

Dynamic vs. Quasi-Static Effluent Limits
Selenium water quality objectives are currently being exceeded in the San Joaquin River, California due to agricultural subsurface drainage discharges. The Federal Clean Water Act requires...

Flexible Water Deliveries: One District's Experience
The Merced Irrigation District (MID) has implemented two significant incentive programs in 1995 to provide surface irrigation water to farmers who have shifted to private wells for irrigation....

Flood Forecasting Model for an Alpine Drainage Basin - River Drau in Austria

Artificial Recharge of a Buried Glacial Aquifer in South Dakota
The Huron Project of the High Plains States Groundwater Demonstration Program was designed to artificially recharge a buried glacial aquifer in eastern South Dakota High flows from the...

Non-point Source Policies for Agricultural Drainage
There is limited experience in regulating the water quality impacts of nonpoint source subsurface agricultural drainage discharges. Recent efforts in California to regulate selenium discharges...

Optimal Well Locations for Groundwater Mound Control

Rethinking Well Efficiency
Many authors have suggested ways to evaluate water well efficiency. Most of these have either compared some form of measured drawdown with theoretical drawdown or measured the fraction...

Wellhead Protection Area Predictions and Implications for the Biscayne Aquifer in Miami, Florida
The need to protect groundwater supplies from sources of contamination is of particular relevance to densely populated urban areas, such as Dade County (Greater Miami), in South Florida....

Wellhead Protection: Local and Community Efforts
The need to protect groundwater supplies from sources of contamination is of particular relevance to densely populated urban areas, such as Dade County (Greater Miami), in South Florida....

Drainage Recirculation Project for Water Quality
The State Water Resources Control Board and the federal Environmental Protection Agency have described water quality objectives for selenium in the San Joaquin River. In order to achieve...

Juvenile Fish Separator Design
Separation by size of downstream migrant juvenile salmonids at hydroelectric projects in the Columbia River basin is an integral part of transportation and bypass programs. However, separation...

CSO Planning Model Development and Verification Strategy
A model verification technique is described that uses modeled and monitored overflow occurrences defined in terms of the same long-term frequency statistics that are used to evaluate CSO...

Development and Application of a Dual Drainage Model for the Wethersfield Area of the City of Hartford, Connecticut
A combined system, with overflows, existed in the City of Hartford, Connecticut. Although effective in the context of design standards prevailing at the time of its original design, the...

Periodic Variation in Karst Stream Losses
A cave taking water from an ephemeral stream periodically reroutes surface and subsurface drainage because of a plug that forms 10 m below the main entrance to the cave. The plug of sand,...

Regional Groundwater Management with Health Risk Assessment
A regional groundwater system may have several areas which are contaminated with organic chemicals. In general, the objective of groundwater management is to supply the demand for water...

Soil Water Chemistry of Irrigation with Drainwater
The use of drainwater for irrigation was demonstrated as a management option that reduces net farm drainage and provides control over water quality (O'Brien and Guitjens,...

BMP for Control of Agricultural Nonpoint Source Flow
Nine ha of spring wheat were sprinkle irrigated with drainwater from 15 subsurface drains. The objective was to demonstrate that use of drainwater for irrigation improves the net efficiency...
