Application of a GIS to a Ground Water Classification System
New more effective methods of ground water management are being developed by the New Jersey Department of Environmental Protection (NJDEP) including an anticipatory conceptual State ground...
TRUMPET: A TR20plus Watershed Model?Version 1.04
The TRUMPET watershed model is a microcomputer application which expands upon the widely used SCS TR20 hydrology computer program by providing user-friendly, interactive input and file...
Comparison of Two Methods for Modeling Urban Runoff
The techniques currently available for modeling urban runoff can generally be grouped into discrete and lumped system approaches. The storm water management model (SWMM) provides procedures...
Daily Water Budget Model for Water Resources Management
A daily water budget model has been developed and tested for the Clinch and Powell watersheds located in SW Virginia and NE Tennessee. The model integrates available data and simulates...
Computerized Bridge Coding for HEC-2 Applications on I.B.M. P.C.
A computer program for conversion of survey field notes directly into SB, BT, and GR cards with simultaneous cross-section plot is described. It was designed to simplify the coding of...
An Investigation into Causes of Bank Caving
A series of investigations into bank caving along the Ohio River are described. These investigations include a study of the distribution of precipitation in the study region, derivation...
Water Conservation and Floodplain Regulation at Barrett Dam?San Diego, CA
Barrett Dam is owned and operated by the City of San Diego, California. This paper describes the response of the dam to heavy storms that occurred in Southern California in 1980. Computer-generated...
Optimal Use and Economic Value of Seasonal Runoff Forecasts
Each year the National Weather Service and the Soil Conservation Service issue a monthly sequence of five (or six) categorical forecasts of the seasonal snowmelt runoff volume for 760...
Forecast Uncertainty in Reservoir Operation
Bayesian decision theory can be of significant value to reservoir operation because of its flexibility in being able to incorporate new information and/or opinions and judgments of decision...
Water Demand Forecasting in Southern California
A study of annual water use in Southern California is made in order to determine the cause of unusually high demands in 1987. Regression analysis of the demands and analysis of ratios...
Water Demand Forecast Uncertainty
This paper examines the effect of water demand forecast uncertainty on the operation of a city's water supply system. It is based on a number of years experience the author...
Underground Storage in Urban Stormwater Management
The use of underground pipe detention basins is discussed. These basins mitigate the frequency of localized flooding and sewer surcharging by effectively increasing the flow capacity of...
Resolving a Groundwater Conflict in Colorado
In 1985, the City of Lakewood, Colorado, submitted applications for permits to drill 20 wells in the Arapahoe Aquifer with the intent of appropriating 4300 acre-feet annually for eventual...
Administration of Water in the 21st Century in Accordance with the Appropriation Doctrine
In accordance with the appropriation doctrine it appears straightforward to distribute water during below-average supply, 'first in time of use, first in right of use'....
BMPs for Urban Stormwater Management in Virginia
This paper presents discussions on applying best management practices (BMPs) in Virginia as part of the Chesapeake Bay clean up program and future information needs....
Field Testing of Selected Urban BMP's
This paper presents the results of field sampling of two urban BMP's (Best Management Practice), namely, a wet detention pond and a level spreader/vegetative buffer strip...
Stormwater Management in Virginia
In the 1986 budget bill, the Virginia General Assembly directed the Virginia Department of Conservation and Natural Resources, Division of Soil and Water Conservation, to conduct a review...
GWPATH: Ground-Water Flow Path Analysis
GWPATH is an interactive software package for estimating horizontal fluid pathlines and travel time in fully saturated groundwater flow domains. GWPATH was developed for the IBM PC-AT...
A Vectorized Polynomial Preconditioned Conjugate Gradient Solver Package for the USGS 3-D Ground-Water Model
A vectorized polynomial preconditioned conjugate gradient (PPCG) numerical algorithm is presented as an additional solver package interfaced with the Modular Three-Dimensional Finite Difference...
Reported Results from 600 Cloud Seeding Projects
The authors conclude that cloud seeding is an effective way of increasing precipitation when applied to the appropriate clouds and climate. Reported results from research projects show...
