Water Management Under Drought Conditions: An Overview of Practices by Non-Federal Entities
This paper provides an overview of water management procedures and practices of non-federal water management agencies under drought conditions. The general components of drought water...
Operation of the Tennessee Valley Authority Water Control System Under Extreme Drought Conditions
The Tennessee Valley region recently suffered through the most severe drought of record. As increasing demands were placed on the reservoir system, operating priorities were modified to...
Soil Moisture and Runoff?Another Look
Infiltrometer studies conducted on numerous soil types in various locations of the United States which had soil moisture data were used to calculate the runoff Curve Number (CN) of both...
Retention Parameter Estimates for Curve Number Runoff Procedure
A technique is developed for computing estimates and associated probabilities of the retention parameter S in the Soil Conservation Service curve number runoff procedure. This technique...
Progress Report ARS/SCS Runoff Curve Number Work Group
The Soil Conservation Service (SCS) Runoff Curve Number (RCN) procedure works well as a single event model to estimate design storm runoff volumes from a small agricultural watershed....
Hydrologic Considerations in Mined Land Reclamation
Thunder Basin Coal Company (TBCC), a subsidiary of the Atlantic Richfield Company, operates the Black Thunder Mine in the Powder River Basin of Northeast Wyoming. The mine, located roughly...
Variations in Curve Number for a Reclaimed AML Site
Runoff and erosion from an abandoned mine land site near Sheridan, Wyoming were monitored for four years following reclamation. Small plots, which included lengths from 12 to 24 meters...
Hydrogeotechnical Considerations for the Disposal of Oil Shale Solid Waste Material
Laboratory tests and five large scale lysimeters (7.3?3.0?3.0 m deep) have been constructed to collect information and data on hydrogeotechnical factors which affect an oil shale solid...
Simulation of Runoff and Infiltration of Disturbed Land
Disturbances of land due to human and natural causes change the porosity and hydraulic conductivity of the soil. A simulation model of conjunctive surface-subsurface flows can be used...
Agricultural Impacts on Surface Water via Ground Water
Three years of ground and surface water quality monitoring data collected from one site in the mid-Atlantic coastal plain are presented. These data suggest that delivery of P from ground...
Assessing the Leaching Potential of Herbicides at the Ohio MSEA
The GLEAMS model was used to assess the potential for herbicide leaching at the Ohio MSEA. Input data, typical of the Ohio MSEA, was used in conjunction with precipitation data for the...
Aldicarb Transport in the Coastal Plain of N. C.
The pesticide aldicarb is extremely soluble in water which causes it to be mobile in ground water. A field study was conducted to monitor the fate of the pesticide aldicarb in a poorly...
Water Quality Implications of Encapsulated Atrazine
This paper presents the movement of both encapsulated and wettable powder atrazine under no-till and conventional-till corn in the Coastal Plain physiographic region of Maryland. Soil...
Water Quantity and Quality for Irrigated Agriculture and Wetlands
A water balance for the Carson Division of the Newlands Project in Northwest Nevada was created to identify the potential recovery of irrigation drainage effluent from the shallow aquifer...
Recycling Wastewater by Drip Irrigation
Hawaii's sugar factories produce about 380 million liters of wastewater per day from sugarcane washing, condensation, and cooling operations. Since 1972, wastewater has been used to irrigate...
Expert System for Agricultural and Water Quality Management
Agricultural activities occur in an open environment where uncontrollable climatic events influence both agricultural productivity and water quality. A decision support system is described...
Management of Agricultural Drainage Pollution Considering Regional Cooperation
Increasing awareness of toxic substance discharge from agriculture in the San Joaquin Valley of California has resulted in discharge limits on individual constituents in agricultural drainage....
Gradual Development of Bores in Canal Systems
Modern computer programs for modeling unsteady flow in open channels are typically constructed using a momentum conserving form of the Saint Venant equations. This allows computation of...
Design of Irrigation Distribution System
This paper briefly discusses the Bureau of Reclamation's process of developing the rehabilitation of the Grand Valley Unit in Colorado. Sections are included on accessing needs of the...
Case Studies of Semi-Closed Pipeline Systems for Flexible Deliveries
The semi-closed pipeline system using the best aspects of the open and the closed pipeline systems, has many applications. It is the best adapted system for use with the variable flow...
