Analysis of Technologies for Small Water Systems
The problems encountered when small systems must meet the provisions of the National Primary Drinking Water Regulations are discussed. Among the potential water quality problems that could...
The Engineering Aesthetics of Tall Buildings
The Proceedings of a session on the Aesthetics and Design of High-Rise Buildings at the ASCE Convention in Denver is included in its entirety. The session was chaired by Lynn Beedle and...
Optimization Issues in the Design and Control of Large Space Structures
The optimization and identification issues which arise in the design and control of large flexible space structures are reviewed. The first paper examines the use of several different...
Gains and Losses of Commingled Waters in a Stream
In a legal dispute in the State of Washington (Colville Confederated Tribes vs. Boyd Walton, Jr. , Farmer), it became necessary to determine the proportion of transmission losses sustained...
Center Pivots: Iron Dinosaurs of Ogallala Aquifer
In mid-1983, USDA's Soil Conservation Service (SCS) staff in Colorado began a 5-year project aimed at reducing the amount of water the state extracts from the Ogallala aquifer....
Rating Systems to Evaluate Onfarm Water Conservation
The U. S. Department of Agriculture, Soil Conservation Service, concentrates its assistance on modernization of onfarm irrigation systems and improvement of water management to provide...
Institutional Constraints and Evaluation of Potential Management Strategies on the Colorado River System
Management of the Colorado River reservoir system is a complex problem influenced by a number of institutional constraints including interstate compact agreements, international treaties,...
Optimization of Irrigation Distribution System Operation
The initial phases of the Federal Central Arizona Project (CAP) are nearing completion and in the latter part of this year the long-awaited delivery of Colorado River water will become...
Use of Drainage Control to Minimize Potential Detrimental Effects of Improved Drainage Systems
Improved drainage systems are necessary on many soils for sustained agricultural production. However, there are several drainage system designs which can be utilized to satisfy agricultural...
Yield-ET Functions in Irrigation Systems Design
A linear-programming (LP) framework and associated computer routines were developed to evaluate economics of deficit irrigation in system design and to optimize the sizing and operation...
Hydrologic Impacts of Improved Irrigation Efficiencies
The Salt River drainage basin (Star Valley) is an agricultural watershed of 829 mi**2 (2150 km**2) in western Wyoming. Salt River stream flows were hydrologically analyzed and a comparison...
Appropriated Water Rights in Utah
The appropriated water rights system used in Utah is discussed. The historical background for establishing this allocation process is reviewed. The process of changing the location and...
Water Requirements of Mountain Meadow Vegetation
Measurements to define agricultural water consumption have been taken in the Green River Basin of Wyoming throughout the summers of 1983 and 1984. The weekly measurements included water...
Effect of Santa Rosa Lake on Ground Water Flow to the Pecos River, New Mexico
In 1980, Santa Rosa Dam began impounding water on the Pecos River about 7 miles (11 kilometers) north of Santa Rosa, New Mexico, to provide flood control and storage for irrigation. Santa...
Water Losses from an Irrigation Canal-Ditch-Dugout System
The general limitations of and requirements for accurate determination of water losses from an irrigation distribution system have been identified. A hydrologic water balance technique...
Scheduling in Manually Controlled Canal Irrigation Delivery Systems
The effects of canal transients on scheduling water delivery to an irrigated area are described using a linearized form of flow equation obtained from a zero-inertia momentum equation...
Daily Weather Forecasts Used to Manage Soil-Water
This paper describes a newly developed method for analyzing the rainfall probability data included in daily weather forecasts issued by the National Weather Service. The purpose is to...
Modeling Flow in an Ephemeral Stream Channel
A particularly distinguishing characteristic of ephemeral streamflow is the large role played by infiltration. Infiltration interacts in a complex way with channel flow to control the...
Innovative Management in a Period of Austerity: The Glamorgan Heritage Cost Experience in the U.K.
Restraint in UK economic growth gave rise to a new countryside management approach which was non-statutory, dependent upon voluntary agreements. In essence the land remains in private...
Monitoring Completed Coastal Projects
In the United States, construction of public works to develop water resources is the responsibility of the Army Corps of Engineers. These works include projects to improve ocean and coastal...
