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...

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...

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...

Use of Stormwater Models to Optimize the Performance of a Regional Stormwater Detention System
implications of stormwater models to develop a regional detention basin master plan for Fairfax County, Virginia are described. Following the selection of candidate sites and detention...

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....

Continuous Drainage System Modeling of Jones Run
A generalized package of hydrologic and hydraulic models has been developed for the quantitative analysis of watersheds and drainage networks. The package is called ODWAP (the Old Dominion...

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...

Small Diameter Gravity and Pressure Sewers
In communities with low population density or physical features that make conventional gravity sewers inordinately expensive, alternative sewer technologies can be significantly lower...

Lessons to be Learned from Lafayette Tennessee's Small Diameter Sewer System
Lafayette, Tennessee's septic tank effluent, small diameter gravity sewer (SDGS) system is believed to have been the first such project to be funded by the United States Environmental...

Comparison of Storm Water Management for Phoenix and Washington, D.C. Urban Areas
The design criteria, the methods of analyses, and the estimated costs of construction are compared for two storm water management systems in the Phoenix, Arizona and the Washington, D.C....

Computer Based Master Plans Manage Water Resources
Scottsdale is pursuing water and wastewater master planning with the goal of implementing a proactive water resources management policy. To prepare dynamic master plans with the above...

Risk Assessment of Lake Shore Development of Devils Lake, North Dakota
In recent years, the advent of the flood insurance programs has forced developers, financiers, and planners to deal with future high water conditions and associated risks. A reliable method...

Vacuum Sewers: Fundamentals and Design Methods
Vacuum sewer (VS) systems have important advantages over conventional gravity sanitary sewers or septic tank-soil absorption systems when one or more of the following conditions hold:...

Vacuum Sewers: Construction and Operating Experience
As an alternative to conventional collection, the vacuum system has many advantages. Smaller diameter pipes, shallower trenches and the ability to make vertical and horizontal field changes...

Alternating Direction Oxidation Ditches?A Cost Saving Technology from Denmark
A soon to be released EPA report claims that in Denmark, small alternating direction oxidation ditches (ADOD) save as much as 70% of the cost for conventional oxidation ditches. The alternating...
