Lawyer on a Microchip
Construction in the 1980s have become a complex, high stakes, intensely competitive business. For architects and engineers involved, the prospect of lawsuits has grown tremendously. An...
Design of Large Steam Turbine-Generator Foundations
This report is a guide for engineers who are responsible for the design and analysis of large turbine-generator foundations. A description of the various components of turbine-generator...
Demand Irrigation Schedules
This class of schedules consists of Demand and Limited Rate Demand. They need no communication system and can satisfy the on-farm needs with negligible constraint. The Demand schedule...
Structuring Distribution Agencies for Irrigation Water Delivery
The performance of an irrigation project is significantly influenced by the organization which distributes water to users. It is demonstrated that a intermediate level authority, typically...
Automated Water Control in Southern Alberta
The distributed control system for water delivery that has evolved in Alberta, Canada is described including the type of hardware used and the general operating philosophy. Of importance...
Selection of Appropriate Technology in Irrigation Canal Systems
A variety of approaches to irrigation management and system operation exist and great care should be taken in selecting the one to be used in new or rehabilitation/modernization projects....
Overview of Financial and Economic Considerations
The financial and economic analyses of plans to rehabilitate and automate irrigation water delivery systems are complex technical exercises that require the expertise of professional economists...
Economic Analysis of Irrigation Rehabilitation Projects
This paper discusses the assessment of the costs and benefits of irrigation rehabilitation and modernization projects. It summarizes the methodology used at the World Bank to assess the...
Open Channel Flow Resistance in Horseshoe Conduits
An experimental study of open channel flow resistance in horseshoe-shaped conduits is reported. The friction factor is shown to increase approximately 20 percent in comparison to values...
Optimal Design of Large Scale Water Distribution Systems
This paper presents a methodology for the design of least cost water distribution systems. The advantage of the formulation compared to the other techniques in the literature is that it...
Composite Resistance to Flow With an Ice Cover
Recent data collected on several rivers in Michigan suggest, with only an ice cover present, that Manning's roughness ratio is constant at n//R equals 0. 65. If other ice...
Mississippi River Sediment Load and Regime Equations
Data collected by the Corps of Engineers were used to evaluate the interaction of such parameters as river slope, suspended sediment load, channel geometry, and river discharge. Calculations...
Roughness Coefficients of Large Floods
Most hydraulic calculations of flow in channels and overbank areas require an evaluation of flow resistance generally expressed as Manning's roughness coefficient, n. Literature...
Non Linear Economic Models for Crop Production
Most economic models for crop production rely on the traditional linear programming approach, in spite of the fact that the objective function is almost always non linear. This paper briefly...
A Simulation Procedure for On-Farm Irrigation Systems Planning
A simulation modeling package has been developed for modeling on-farm irrigation water supply and application systems. The modeling package can consider up to 6 different application systems...
Selenium Removal?Can We Afford It?
The process of biologically removing the element selenium from agricultural drainage water is discussed and an economic evaluation of the process is presented. If by-products can be recovered,...
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....
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...
CWSI and Stomatal Resistance of Cotton and Soybeans
A new instrument, Scheduler(TRADEMARK), has been developed to measure the onset and duration of plant water stress. This device consists of a sensor package (containing an infrared thermometer,...
