Economic Analysis Tools for Differential Inflation
Economic decisions based on a life-cycle analysis should consider differential increases or decreases in operation and replacement costs and benefits over the project or component life....
The Animas-La Plata Project Cost Sharing Agreement
The United States Congress required a cost-sharing agreement between the project beneficiaries and the Federal government. Under this agreement of June 30, 1986, the project will be constructed...
Future Directions on World Bank Irrigation Projects in India
Irrigation development in India is proceeding at a record rate and will continue for several decades. Experience, however, is showing that future directions must entail substantive emphasis...
Economic Benefit of Irrigation on Beef Ranches
Drought can result in forage shortages leading to possible liquidation of the breeding herd. Liquidation is often at depressed prices, and replacement may be at elevated prices. In this...
Winery Wastewater Land Application
Winery wastewater is characterized by low pH, relatively high BOD, and a low nutrient content. Land application using rapid infiltration basins has been practiced successfully at a number...
Management Challenges Affecting Agricultural Reuse of High-Strength Food Processing Wastewaters
Land treatment of high-strength food processing wastewaters is a viable pollution control technology. Due to the high-strength characteristics of these wastewaters, effective site management...
Steady State Fluid Transport Model for Plants
Knowledge of water potentials throughout the xylem and phloem elements as well as in individual cells is fundamental for understanding effects of water and temperature stress on transport...
Evaluation of Methods to Determine Peak Period Irrigation Water Requirements
Methods for estimating the peak period irrigation water requirement were evaluated as a component of the review of irrigation facility sizing criteria conducted for the Engineering and...
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....
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...
