Monitoring Water Quality and Use in Colorado
This paper presents the results of a two year study on the impact of irrigation water use on water quality near Greeley, CO. Data on irrigation application efficiency, deep percolation,...
Statewide Consumptive Use Estimates
Methodology for estimating consumptive use and consumptive irrigation requirements on a statewide basis is summarized. The methodolgy has been used to update monthly and seasonal consumptive...
Wetland Loss Rates and Agricultural Drainage
The current paper uses National Resources Inventory data to document the relation between private on-farm agricultural drainage investment activity and wetlands loss. The paper presents...
Wastewater Reclamation at Davenport, Washington
The City of Davenport, Washington went through an extended process to update their undersized wastewater treatment and irrigation reclamation systems for municipal wastewater. The process...
Water Infrastructure Risk Ranking and Filtering Method
The availability of water distribution infrastructure is critical to the sustained support and growth of society. Water infrastructure consists of systems that carry water (pipe and irrigation...
Environment-Irrigation Trade-Offs and Risks
Allocation of scarce water resources between environmental and commercial uses is an extremely important problem in many parts of the world. A study is under way in Australia to examine...
Expert Analysis in Regulated Irrigation Canal Modelling
Application of riverine unsteady-flow numerical modelling techniques to problems of flow regulation in irrigation canals invokes the need for careful treatment of some situations not commonly...
Effects on River Mechanics Due to Reduction in Low-Season Discharge
India's diversion of water from the Ganges River 11 miles upstream from Bangladesh's western border during the low-flow season seriously adversely affects Bangladesh's irrigated agriculture,...
ISTEA Enhances Transportation
The aim of the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 was to integrate communities with transportation programs. Engineering professionals now have the responsibility...
Ag-To-Urban Water Transfer in California: Win-Win Solutions
Water transfers from farms to the cities are widely viewed as the next major source of supply to urban California. Ag-to-Urban permanent water transfers may have negative consequences...
Water Allocation: Matching Supply with Demand
The Colorado-Big Thompson (C-BT) Project was designed in the 1930's as a supplemental water supply for water users in northeastern Colorado. Since that time the water allocation has shifted...
Technical and Organizational Constraints on Surface and Groundwater Irrigation in Small-Holder Areas of S. Asia
Variable irrigation supply and the independent character of the S. Asian small-holder combine to present a difficult problem in irrigation management. Attempts to introduce advanced technology...
Bellingham Frozen Foods Spray Irrigation System Operations
Bellingham Frozen Foods is a major vegetable processor located in northwestern Washington state. During the mid-1980's, the city of Bellingham began to upgrade the treatment of wastewater....
Agricultural Water Conservation Programs to Improve Water Use Efficiency
California's growing population poses an ever increasing demand for water from the existing limited and scarce water resources of the State. In addition the continuation of six years of...
Agricultural Water Conservation Programs in the Lower Colorado River Authority
Rice irrigation is the largest application of water within the area served by the Lower Colorado River Authority, accounting for approximately 75 percent of total annual surface and ground...
Agricultural Water Conservation Technology Transfer
Efforts to implement computer programs which encourage water and energy conservation in the Columbia Basin, are described. Irrigators use the irrigation scheduling program to receive recommendations...
3D Template of Human Figure for CG Animation in Design
It has become commonplace to use computer graphics (CG) animation in architectural and landscape design. Historically, CG animation has been employed primarily as one of many presentation...
CAD System for Structural Aesthetics of Bridge Form
An exploratory design process for aesthetic bridge structure is proposed in this paper through developing a prototype of comprehensive CAD system. This process is conceived not only for...
Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...
Predicting Impacts of Management Measures on Fragile Coastal Wetlands Using a Predictive Landscape Model
We present a marsh development model that incorporates the hydrodynamics of erosion and sedimentation and meets all conventions proposed for spatial landscape modeling. Wave parameters...
