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...
Investigation of Main Supply Canal and Lateral Fluctuations
The Imperial Irrigation District and the U. S. Water Conservation Laboratory of Phoenix, Arizona are conducting a joint project to study the causes and effects of water level fluctuations...
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...
Water Supply Forecasting and Irrigation Demand
The Soil Conservation Service (SCS) Snow Survey Program makes periodic seasonal streamflow forecasts at over 500 major points in the western states. These forecasts are the basis for making...
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....
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 Supply Analysis for the Milk River Basin, Montana
The U. S. Bureau of Reclamation's Milk River Irrigation Project provides water for 55,000 ha of irrigation in the Milk River basin of Montana. The project includes an interbasin...
Missouri River Basin Water Accounting System
A water accounting system was developed for the Missouri River Basin to establish an accurate and acceptable base of information describing water availability and uses, and to provide...
Long-Range Forecasts of Water-Supplies
Many engineers and water-users have an urgent need for reliable predictions of future rainfall and water supplies, extending many months or years ahead. Correlation of known historic rainfall...
Water Supply Demand Forecast
In this study, estimates of location, quantity and timing of water demands have been investigated for determination of the adequacy of an existing water supply system, the need for additional...
Localized Effects of Subsidence on Flooding in a Small Urban Watershed
Extensive pumpage of groundwater in the Houston, Texas, metropolitan area in the last century has caused compaction of the clay layers in the local aquifers with resulting widespread land...
A Linked Stream-Aquifer System Model
A linked stream-aquifer system (LISAS) model is described. This model includes a deterministic sequential flow simulation component which generates hydrographs of surface runoff and deep...
Seepage/Drainage Investigation Colusa County California
High groundwater in the late winter months saturates the soil profile, causing damage to both crops and soil. Sustained water logging severely damages or destroys orchards. It has generally...
Evaluation of Surface-Water - Ground-Water Interaction Coefficients in Water-Resources Planning Model
A water-resources planning model formulated as a mixed-integer program is used to screen and sequence proposed projects such that the present cost of meeting future water demands is minimized....
Groundwater Modeling - A Management Tool
A hydrogeologic investigation within the South Mountain Complex of south central Pennsylvania was performed to develop a groundwater management program. Using LandSat imagery, low altitude...
Effect of Length of Precipitation Record on Recharge Estimates
The effect of the length of precipitation record on groundwater recharge estimates is examined using data from eleven precipitation gages located on the Nevada Test Site. It is concluded...
Well Field Management Designed to Miminize Impact on Surface-Water Flow
Restrictions placed on the operation of a well field used for public water supply initiated an investigation to develop management techniques that would maximize utilization of the well...
A Probabilistic Method for Determination of the Required Capacity of Reservoirs
Evaluation of water supply potential of multi-purpose dams generally involves determination of the required capacity of reservoirs for new dams and analysis of safe yield or reliable yield...
