Missouri River Basin Water Accounting System
A water accounting system was developed for the Missouri River Basin to establish an accurate and acceptable base of information describing water availability and uses, and to provide...
Optimizing a Minimum Instream Flowby
The Commonwealth of Virginia is currently investigating methods to establish minimum instream flow requirements which may be applied to flow allocations statewide. The Crump Creek Reservoir...
Mesonets--A Solution to Improving Flood Forecasting
Floods continue to cause major destruction annually despite the efforts of Federal water resources agencies. Improved flood forecasts can reduce flood damages and corresponding loss of...
The Northwest Watershed Research Center, 1959-86
Hydrologic research has been conducted on the Reynolds Creek Experimental Watershed by the Agricultural Research Service for nearly 27 years. Some noteworthy instrumentation, developed...
HEC-1 and HEC-2 Applications on the Microcomputer
The Hydrologic Engineering Center (HEC) has developed versions of the HEC-1 Flood Hydrograph Package and the HEC-2 Water Surface Profiles programs for MS/PC-DOS compatible microcomputers...
Theory for Development of the TR-55 Tabular Hydrograph Method
Technical Release No. 55 (TR-55), 'Urban Hydrology for Small Watersheds,' was originally developed by the United States Soil Conservation Service (SCS) in the...
Interagency Standards for Automated Local Flood Warning Systems
The need exists for establishing guidelines and standards for aspects of local flood warning systems. The demand for increased flood warning systems is expected to increase due to the...
A Linked Stream-Aquifer System Model
A linked stream-aquifer system (LISAS) model is described. This model includes a deterministic sequential flow simulation component which generates hydrographs of surface runoff and deep...
Evaluation of Surface-Water - Ground-Water Interaction Coefficients in Water-Resources Planning Model
A water-resources planning model formulated as a mixed-integer program is used to screen and sequence proposed projects such that the present cost of meeting future water demands is minimized....
Kinematic, Diffusion and Dynamic Catchment Modeling
This paper reports on a series of tests aimed at developing improved procedures for catchment routing. The objective is to compare kinematic and diffusion models within several scenarios...
Transport Model for Aquifer Reclamation Management
A contaminant transport model which is specifically designed for management applications is developed. A key feature is the transient velocity field needed in the solution of the advection-dispersion...
Modeling Coal Pile Leachate - A Case Study
Ground water transport of coal leachate from an existing unlined coal storage pile was modeled using the USGS 'Computer Model of Two-Dimensional Solute Transport and Dispersion...
Groundwater Quality Modeling at Redlands/Crafton Area
Organic groundwater contamination exists in the Redlands area of the Bunker Hill Groundwater Basin which is of major concern to the health and water agencies in the region. The contaminants...
Estimating Low-Flow Frequencies of Ungaged Streams in New England
Equations to estimate low flows were developed using multiple-regression analysis with a sample of 48 river basins, which were selected from the U. S. Geological Survey's...
Utility Programs for DWOPER and DAMBRK
Time and computer resources greatly limit potential investigations and sensitivity anslyses. In order to facilitate modeling with the National Weather Service (NWS) programs DWOPER (Operational...
Application of the New SCS Time of Concentration Method
The second edition of the Soil Conservation Service (SCS) TR-55, published in June 1986, introduces a new method for calculating the time of concentration for storm runoff flowing through...
Some New Snyder Type Coefficients for Small Watersheds
Data collected on the Goodwin Creek watershed has produced a continuous hydrologic record from 37 rain gages and runoff record from 14 runoff stations within a drainage area of 8. 26 sq...
Changing Hydrology - The Middle Mississippi River
Observed daily flow and stage at major stream gages on the middle Mississippi River are numerically and graphically analyzed to quantify and illustrate the magnitude and seasonality of...
The Dallas Floodway Project
This paper explores the history of the Dallas Floodway project, past performance of the project under various flood conditions, recently updated hydrologic and hydraulic evaluations, and...
Criteria for Selecting a Reservoir Routing Method
Results of an investigation comparing dynamic and storage reservoir routing applied in dam safety analyses are presented. Outflow hydrographs computed by these reservoir routing methods...
