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...
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...
Data Base in Your City's Future?
The city of Bellevue, Wash. computerized its public works maps in 1979 because Bellevue was using the county's maps, and their updating wasn't keeping up with suburban growth. Now this...
Jointless Bridge Decks
Deck joints in a bridge are the source of many problems over its lifetime. In time, chances are good the joint will leak, permitting water and salt to leak through. Often this leads to...
Tampa Does It with Mirrors
As one of the nation's fastest growing cities, Tampa needed far more public works dollars. But the traditional source, the real estate tax, can no longer be relied on so heavily,...
Engineering with Fabric
Geotextiles are lending their strength to construction projects where conventional methods won't work. At Washington National Airport, an embankment was built into the Potomac...
