Economic Incentives Encourage Improvements In Farm-Level Water Management Practices
The Broadview Water District has implemented economic incentive programs in recent years to encourage improvements in irrigation practices to reduce the volume of subsurface drain water...

Water Quality Improvement Program in Ventura County at Port Hueneme
Integrated resource planning (IRP) has been used successfully by several larger water utilities to resolve complex water supply issues. This paper describes the experience of a smaller...

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...

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...

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...

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...

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,...

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...

Shallow Ground Water Management with a Modified Subsurface Drainage System
An existing subsurface drainage system was modified to control the flow from the drain laterals and to control the water table depth on a portion of the field. Tomatoes and cotton have...

Efficiencies of Drainage Systems and Improved Water Management
Drainage of agricultural lands has become a contentious issue as concern increases over the actual economic benefits of subsurface drainage in irrigated regions relative to the impacts...

Effective Subsurface Retention/Detention Systems
Stringent environmental regulations and increasing land values have made finding an effective way to manage storm water runoff a high priority for consulting engineers and land developers....
