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...
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
