Rainfall Intensity-Duration Equations
A method for rapidly developing a rainfall intensity-duration equation for durations less than one hour and recurrence intervals between 2 and 100 years for any location in the conterminous...
Partial Area, Variable Source, Rainfall Runoff Model Utilizing Digital Mapping
A partial area, variable source hydrologic rainfall/runoff model, called MAPHYD, was developed utilizing digital maps, interactive computer graphics, and several infiltration mechanisms....
A Shopper's Guide to Urban Stormwater Software, Revisited
Results of a survey of urban stormwater software were first discussed by the author in August, 1985. A trend toward widespread adoption of SCS procedures as a new standard in urban hydrology...
Habitat and Water Quality Considerations in Receiving Waters
Temporal issues of importance include timing, magnitude, and return frequency of flow conditions as well as duration of exposure (concentration) and return frequency of specific exposure...
Technological, Hydrological and BMP Basis for Water Quality Criteria and Goals
Water quality criteria and goals may be addressed through at least four means: institution of 1) technology-based controls, 2) best management practice (BMP) based controls, 3) water quality...
Cost-Effectiveness and Urban Storm-Water Quality Criteria
This paper reviews alternative methods of evaluating the effectiveness of investments in urban stormwater quality improvement. Experience in the related area of control of dry-weather...
Basis for Design of Wet Detention Basin BMP's
Two different approaches have typically been used to formulate design criteria for wet detention basin best management practices (BMP's). One approach relies upon solids settling...
Long Term Performance of Water Quality Ponds
A report developed under EPA's Nationwide Urban Runoff Program (NURP) describes an analysis methodology and presents graphs and example computations to guide planning level...
Rainfall Analysis for Efficient Detention Ponds
Intensity-duration-frequency analysis of rainfall data is traditionally used for the selection of design storm required to size, storage capacity in detention/retention ponds without consideration...
Monitoring and Design of Stormwater Control Basins
The City of Austin, Texas, has played a pioneering role in the control of urban nonpoint source pollution by enacting watershed and stormwater ordinances, overseeing detailed monitoring...
Design and Construction of Infiltration Trenches
This paper discusses the use of infiltration trenches as a stormwater management practice. Feasibility, design and construction techniques are presented to improve the performance and...
Swedish Approach to Infiltration and Percolation Design
Design of infiltration and percolation facilities is similar to detention facilities. The storage volume of an infiltration basin being the ponding volume on top of the infiltration surface...
Institutional Aspects of Stormwater Quality Planning
Planning and implementation of programs to control the quality of stormwater runoff in urban areas are carried out within institutional frameworks that directly influence the effectiveness...
Urban Runoff Management?An Industry Perspective An Opinion
Coors presently produces about 17 million barrels of beer per year from a single plant about 15 miles west of Denver. The company chose to keep the responbibility for the quality of its...
Summary of Institutional Issues
The paper presents a summary of three other papers presented at the meeting on institutional aspects of stormwater quality planning. The three papers represented views expressed by representatives...
Source Control of Oil and Grease in an Urban Area
We explored a variety of techniques to remove oil and grease from urban stormwater runoff. Previous work has shown that relatively high concentrations and substantial mass loadings of...
Long-Term Effects of Urban Stormwater on Wetlands
In 1986 scientists and managers associated with local, state, and federal agencies that have wetland protection and stormwater management responsibilities in the region joined to consider...
Design of Urban Runoff Quality Controls
This book describes current practice in the design of pollution controls for urban runoff. The contents comprise the proceedings of an Engineering Foundation Conference held in July 1988,...
Ground Water Recharge Through Wells
Surface runoff water accumulates in natural depressions called playas on the Southern High Plains; most of it is wasted by evaporation. The water is turbid, but otherwise of good quality...
Subsurface Injection of Storm Water Runoff into an Underground Storage of Bangkok
Subsurface injection through a well into sand and gravel formations of the Bangkok aquifer of untreated canal water whose composition considered similar to that of storm water runoff,...
