Geochemical Mass-Balance in a Small Forested Watershed in Southwestern Pennsylvania
An intensive hydrologic investigation of the North Fork Bens Creek Watershed on Laurel Hill in southwestern Pennsylvania was made during 1984-85. Precipitation was sampled weekly, and...
Use of Stable Isotopes, Tritium, Soluble Salts, and Redox-Sensitive Elements to Distinguish Ground Water from Irrigation Water in the Salton Sea Basin
Evaporative concentration of irrigation water diverted from the Colorado River to the Salton Sea basin for several decades has produced an overlying system (that includes drainwater and...
Enhanced Canal System Scheduling Using a PC
The Bureau of Reclamation (the Bureau) and Lower Colorado River Authority (LCRA) are promoting water conservation through the development of computer software to enhance accounting and...
Transportation of Cities' Colorado River Water in the Salt River Project's Canal System
Cities in the Phoenix, Arizona, metropolitan area have contracted with the Central Arizona Water Conservation District to take delivery of Colorado River water. Many of their water treatment...
Heavy Metal Transport in the Columbia River, British Columbia
Data on the total forms of selected metals were used to assess their concentrations at two sampling sites on the Canadian Columbia River from 1984 to 1989. Cadmium, the response variable...
History of Irrigation Water Development in Hawaii
Hawaii has a rich heritage of irrigated agriculture from the time of the first Polynesian settlers to the present. Following the ancient stream diversions by Hawaiians, sugar planters...
Imperial Irrigation District Water Conservation
Imperial Irrigation District (IID) and Metropolitan Water District (MWD) have entered into a Water Conservation Agreement to conserve 106, 110 acre-feet (1.31 ? 108...
Forecasting Irrigation Water Supply Using a Computer Model and Remotely Sensed Snow Cover
Improved streamflow forecasting in the Sevier River Basin is one objective of the Sevier River Water Management Study. Short-term forecasts are needed for optimum operations of irrigation...
Uncertainty in Climate Change and Drought
A series of projections of climate change were applied to a watershed model of the Delaware River basin to identify sources of uncertainty in predicting effects of climate change on drought...
Effect of Nile River Flow on Performance of Shoubrah Power Plant Cooling System
Shoubrah El-Khimah Power Plant was built in 1982. Its peak capacity is 1200 MW, generated by four units, three of them having one cooling water intake. The cooling water pumps suffer from...
Bed Forms of Nile River
In this paper, the observed bed forms for six different reaches of the Nile River in Egypt are described. The purpose of the study is to inquire whether or not the different available...
Sediment Transport Measurements in the Nile River at Bani Mazar
Measurements of sediment transport on the Nile River were conducted at Bani Mazar (200 km South of Cairo) during high and low water stages. Bed-load and suspended-load transport rates...
Movable-Bed Model to Evaluate Nile River Dredging
About 200 km south of Cario, at Bani Mazar reach, the Nile River has widened and formed several islands. The result is three channels with shallow depths. One of the branches must be improved...
Application of Stable Channel Design Method
Systematic stable channel design methods are currently being developed by the US Army Engineer Waterways Experiment Station for use in the planning stages of local flood control projects....
Hydraulic Aspects of Grade Control Structures
This paper describes the function of grade control structures. The primary purpose of a grade control structure is to maintain or establish a desired bed elevation in a channel. Basically...
Bed Load Roughness in Supercritical Flow
A supercritical concrete channel is proposed for Mission Creek located in Santa Barbara County, California. The proposed channel may transport gravels and cobbles as bed load during large...
Relationship Between Scour Depth and Bend Radius of Curvature on the Red River
Studies of bank and bend processes were undertaken on the Red River between Index, Arkansas and Shreveport, Louisiana in connection with the navigation project on the river downstream...
Riprap Design Criteria for the ARS Low Drop Structure
The ARS low drop grade control structure has proven to be an effective means to stabilize incised channels in Mississippi. However, field inspections and laboratory testing have indicated...
Operational Procedures for Estimating Bottom Exchange Rates
After briefly reviewing the terminology of the various bottom and water column exchange fluxes, the body of this paper summarizes five possible procedures for establishing operational...
Design of Groins on the Middle Rio Grande
The Albuquerque Projects Office of the Bureau of Reclamation wanted to use groins in place of revetments at two sites on the Rio Grande. The Bureau of Reclamation has limited experience...
