Eutrophication and Recurrent Hypoxia in the New York Bight: A Synthesis of Historical Data and a Numerical Model of the 1976 Anoxic Event
As a result of oceanographic programs conducted over the past four decades, a large historical data base is available, and has been used, to document areas of recurrent hypoxia and high...
High Level Radioactive Waste Management 1990
The proceedings of the first annual Conference on High Level Radioactive Waste Management, held on April 8-12, 1990, Las Vegas, Nevada, provides information on the current technical issues...
Behavior and Design of Gravity Earth Retaining Structures
This paper summarizes recent research on the soil-structure interaction of gravity earth retaining structures and provides new design procedures for these structures. The procedures currently...
Portland's Light Rail: A Successful Public Private Partnership
During its first year, Tri-Met's Light Rail service, MAX, carried twice as many riders as originally projected. What is generally not understood is that MAX is more then a...
South Boston Piers Transit Project
The Massachusetts Bay Transportation Authority (MBTA) is proposing to construct a new transit connection between downtown Boston and the South Boston Piers area. The MBTA has worked with...
Management of Groundwater Overdraft in the Phoenix, Arizona, Area
By law, the overdrafting of groundwater in the Phoenix, Arizona, area must cease by the year 2025. Safe yield can be achieved by means of conservation, water supply augmentation, and condemnation...
Supplemental Irrigation by Runoff Farming: An Economic Assessment
A simulation model was used to evaluate the economic potential for using runoff farming techniques for growing grain sorghum at two locations in Texas. The results show that the yearly...
Sprinkler System Design for Frost Protection
Both undertree and overtree systems for frost protection by sprinkling are currently being used. The criteria based on experimental results and theoretical modeling have been reviewed...
A Modern Approach to the Design of Grassed Channels
The design of grassed channels can be based on modern fluid mechanics principles. The resistance to flow in a grassed channel is linked directly to the relative roughness of the flow through...
The Colorado River Salinity Program?An Overall Perspective
Economic losses resulting from increases in salinity in the Colorado River system were estimated to be $311 million annually in 1986. As a result of protests by Mexico to the United States...
Strategies to Reduce Salt Load in Drainage Water
A study of irrigation efficiency, drainage flow and trace element loading in the drainage water from a 14000 ha irrigation district on the west side of the San Joaquin Valley of California...
Reduction of Deep Percolation and Drain Water
Management of irrigated agriculture for control of toxic trace elements in agricultural drainage waters must include consideration of a variety of factors and their interactions with one...
Economic factors of Drainage Water Reduction
Properly designed and maintained pressurized systems provide better irrigation control and greater infiltration uniformity. But irrigation costs are increased. Imposition of drainage water...
Treatment, Reuse and Disposal of Drain Waters
Treatment, reuse and disposal options of agricultural drainage water present formidable technical problems. Various treatment technologies and disposal methods have been studied. Reuse...

The Bearing Capacity of Debris Flows
Debris flows are made of a cohesive muddy matrix in which large and heavy particles exist in suspension. To explain how these particles are maintained in suspension, several mechanisms...
Feasibility of Stormwater for Recharge in the Las Vegas Valley
Rapid growth in the Las Vegas Valley has increased the pressure on the limited water supply. The increased water demand has stimulated public interest in water conservation and the potential...
Predicting Stream Width and Bank Retreat
The width of streams is dependent on the flood flow discharge which varies from year to year, the bank material which varies from stream to stream and reach to reach, the sediment load...
Resistance Consisting of Both Viscous Force and Dispersive Force
A set of specially designed experiments have been carried for studying the resistance of a flow consisting of water and both fine and coarse particles. The viscous force caused by fine...
A Reservoir Yield Evaluation in an Arid Climate
Yield calculations rarely can be more accurate than roughly plus or minus twenty percent. The same uncertainty is dramatically greater in arid climates where the average annual runoff...
