Development and Management Aspects of Irrigation and Drainage Systems
The 1985 Irrigation and Drainage Division Specialty Conference held in San Antonio, Texas on July 17-19, 1985 covered major topics on watershed management and water conveyance, drainage...
Computer Applications in Water Resources
The use of computers in all engineering disciplines has, in the past decade, increased to the point where virtually all engineers now use these powerful tools. This is especially true...
Environmental Engineering
The purpose of the annual Conference on environmental engineering is to pursue scientific knowledge and promote sound engineering judgement and practice in the solution of environmental...
The PowerBarge Hydroelectric Plant
Following an account of the need for such an approach, the PowerBarge hydroelectric plant design concept is described as a fully floating system consisting of an Intake Barge, Siphon Penstock,...
Membrane Sealing of Rouchain Dam
A synthetic sealing membrane was used to prevent excessive leakage through the facing of an embankment dam. The works, which were completed rapidly and at low cost, enabled the reservoir...
Concrete Face Rockfill Dams of the Winneke Project
Two of the three dams forming the Winneke Reservoir, near Melbourne, Australia, are concrete face rockfill dams. A minor dam forming the sludge storage pond for the project's...
Design and Performance of Shiroro Rockfill Dam
Shiroro Dam, constructed across the Kaduna River in Nigeria, is a rockfill dam with reinforced concrete facing. The dam was completed in late 1983, and reservoir impounding started in...
Design Features of Salvajina Dam
Salvajina dam is the second highest concrete face rockfill dam currently in service in the world. The characteristics of the foundation of the toe slab vary from fresh, sound and little...
Seismic Design of Concrete Faced Rockfill Dams
The results of analytical studies of the stability of the slopes of concrete-faced rockfill dams under different levels of earthquake shaking are presented and used to propose desirable...
Performance Prediction for Removal of Odorous Organics From Drinking Water by Adsorption
The authors address three questions: What do packed bed filters remove from suspension in water treatment plants? How do they accomplish this removal? How can this knowledge be used in...
Particles, Pretreatment, and Performance in Water Filtration
Relationships among raw water quality, pretreatment facilities, and the design of packed bed filters are presented and applied. The particle size, particle concentration, particle surface...
Automation of Booster Pump Stations
Several techniques have been used to automate booster pump stations for irrigation conveyance systems. These pump stations typically must supply pressurized water for a wide range of flow...
Physical Evaluation of a Buried Drainage System
The drainage problem in the 600,000 acre (1. 5 million ha) Westlands Water District (District), located in the Central San Joaquin Valley in California is that of a perched saline groundwater...
Effects of Streambed Processes on Interaction Between Surface and Groundwater
In open channel systems, the phenomena commonly referred to as 'clogging' is caused by settling of sediment and straining of suspended material as water moves...
Time Rated Infiltrated Depth Families
A new set of infiltration families has been developed, for 'normal' soils to describe cumulative infiltrated depth versus time. This new family of curves is described...
Streamflow Losses in the Santa Cruz River, Arizona
The discharge and volume of flow in a peak decrease as the peak moves through an 89-mile (143 km) reach of the Santa Cruz River. An average of three peaks per year flow the length of the...
Updating the New York City Water System
The New York City Bureau of Water Supply maintains extensive records of all water main breaks dating back at least as far as 1940. A computerized file of the main break records was prepared...
Water Quality Issues at Fossil Fuel Plants
This publication highlights proposed approaches and actual projects for dealing with such water quality issues at fossil power plants as water supply, water treatment, and the protection...
Innovative Powerhouse Designs
Since 1978, interest in small scale hydroelectric projects in the U.S. has jumped to a new high. Both new sites and modification of existing dams have received scrutiny by both private...
Stormwater Detention Outlet Control Structures
The Hydraulics Division's Task Committee for the Design of Stormwater Detention Outlet Control Structures was formed to review and report on the state-of-the-art of stormwater...
