Review of the Lake Andes-Wagner Project Sizing
Benefit-cost analyses of the proposed U. S. Bureau of Reclamation Lake Andes-Wagner Project have shown the project to be marginally feasible. In an effort to improve the benefit-cost ratio,...
The Inflatable Weir and Its Widespread Employment for Irrigation in Japan
Although introduced in the U. S. in the 1950's for groundwater recharging, the inflatable weir has become established only in Japan, in which case it is used almost entirely...
Subsurface Drains Solve Groundwater Rise Problems
Four sub-surface drainage alternates were evaluated for lowering the rising water table. Horizontal gravity drainage system offered the best solution to the problem. Disposal of drained...
Prognostics of Water Management in Agriculture
This paper discusses principles of methodology and application of agricultural water management prognostics. Included are irrigation and drainage prognostics in Hungary and concrete economic...
An Integrated Rehabilitation Procedure for Gravity Systems
Demands for an improved system combined with a more adjusted management mode are common in many projects where limited or strained budgets do not allow for a regular and secure water supply....
Managing Water Resources Using Geographic Information Systems as a Tool
The Oregon Water Resources Department is designing and using a geographic information system (GIS) to manage water rights. The system allows automation of many tasks including: production...
Water Resources Planning Information Available from CFS
Public officials, natural resource management agencies, research scientists, reservoir operators, and agricultural interests in the western U. S. now have access to several major automated...
Water Table and Salinity Movement in a Silty Clay Soil
The movement of the water table and profile salinity in a shallow drained soil in permanent pasture overlying an artesian aquifer was observed. Soil samples were taken before and after...
Operation of Glen Canyon Dam during 1983 and 1984 and the Repairs of Glen Canyon Spillways (
The gates at Glen Canyon Dam were closed in the spring of 1963 and the reservoir did not fill until the summer of 1980. The spillways were tested in 1980 with only slight evidence of operational...

Nuclear Waste Disposal: Where Are We?
The U.S. Department of Energy is conducting preliminary site characterizations for three candidates for nuclear waste disposal. The sites are in three different geologic sites. A Richland,...
Building a Team, Not Just a Building
The best way to resolve construction disputes is to head them off. And the best time to step in is before your contractor is hired. In the private sector, there is no reason to open the...
Queensboro Bridge Inspection and Rehabilitation
An in-depth inspection of the Queensboro Bridge revealed deterioration of certain elements on the lower level of the main bridge. These elements include the outer roadway cantilever brackets,...
Rehabilitation of the SF Calawah River Bridge
The failure of a 4-span reinforced concrete bridge in Washington State initiated a study that ultimately led to a unique method of bridge rehabilitation. Severe scour resulted in settlement...
Design of Bridge Piers Against Ship Collision
Design rules for unprotected bridge piers, using uniform safety requirements, are proposed. The selection of an appropriate design vessel is based on a risk assessment model which uses...
Sunshine Skyway Ship Collision Criteria
The 'new' crossing of Sunshine Skyway was born, not only to replace the previous crossings and improve the regional economy but also with increased clearances...
The Far? Bridge?Long Life at Low Costs
The superstructure of the bridge is a steel structure which proved to be competitive compared to the tendered concrete solution, due to simple and rational design both structurally and...
The Applicability of Satellite Altimetry Data to Tidal Models
Different tidal regimes require different data assimilation schemes. In all cases, however, it is better to perform a separate tidal solution before assimilation. For proper assimilation...
General Considerations for Managing Floods and Droughts
Work described at this conference and future developmental work of water resource engineers will best contribute to professional improvement if such work is guided by appropriate objectives....
