Selecting a Stormwater Service Level for Urban Control
Recently, more and more emphasis is being placed on the maintenance of pre- and post-development runoff peaks from a specified design storm. The limit on post-development flood peaks requires...
Use of Continuous Simulation Versus the Design Storm Concept for Water Quality
The validity of the design storm concept has been challenged by several investigators since the development of computer simulation models. Of particular interest are the studies that compare...
Real-Time Monitoring and Flood Forecasting
An automated flood warning system is now serving the 2,700,000 residents of Houston, Harris County, Texas. Real-time rainfall and river level data from more than 150 sensors are automatically...
New Developments in HEC Programs for Flood Control
Since the Hydrologic Engineering Center (HEC) started in 1964, the evolution has been toward packaged programs that perform a variety of computation options. Two examples are the flood...
Prediction of Sediment Yield for Southern California Watersheds
The objective of this paper is to present a scientific method based on multiple linear regression analysis between the sediment yield per square mile and a number of physically realistic...
Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...
Intense Storms and the Runoff Coefficient
During prolonged, intense storms the runoff coefficient increases in value and approaches one irrespective of the vegetation and soil characteristics of the watershed. As the runoff coefficient...
Interaction Between the Technical and Political Processes in Solving Flooding Problems at the Great Salt Lake, Utah
The Great Salt Lake occupies the lowest point in a drainage basin of approximately 22,000 mi**2 (57000 km**2). Inflows to the lake occur as surface runoff, groundwater flows, and precipitation...
Policy Issues in Managing Nonpoint Source Pollution
Attention is first given to the extent of the right of the landowner to generate contaminated runoff. The previously recognized privilege of landowners to make point source waste discharges...
Financial Development for Projects
An important element in the total package of Bechtel's engineering and construction services is the financing and commercial assistance offered in support of our client's...
PC-RUNOFF and dBASE III for Stormwater Data Management, Planning and Design
A version of the RUNOFF Block of the Stormwater Management Model (SWMM) has been extensively revised for the Microcomputer Stormwater Simulation Manager (MSSM). In addition, PRERUN, a...
Application of Lotus 1-2-3 to SWMM Preprocessing
This paper describes a preprocessor for the EPA Stormwater Management Model (SWMM) which is based on a Lotus 1-2-3 spreadsheet. Currently-used methods to input data into SWMM are described...
Conference Overview
An Engineering Foundation Conference organized by the ASCE Urban Water Resources Research Council was held at New England College in Henniker, New Hampshire, June 22-27, 1986. This paper...
Conference on Urban Runoff Quality-Objectives
The agenda for this conference on urban runoff quality was structured to expedite technology transfer through the expression, consolidation and evaluation of opinions, facts, experience...
Report on NATO Workshop on Urban Runoff Quality
Major presentations and discussions from the 1985 NATO advanced research workshop on urban runoff quality are summarized. The topics discussed include the characterization of urban runoff...
Modeling Urban Runoff Quality: State-of-the-Art
Procedures used in urban runoff quality modeling are reviewed in the context of common objectives of urban runoff quality analysis. The need for calibration/verification data is emphasized...
Physical and Chemical Data Needs for Design
The problems and deficiencies in the existing characterisation and evaluation of urban stormwater runoff quality are examined through discussion of adopted and proposed design criteria...
Toxicology and Chemistry of Metals in Urban Runoff
Water quality characteristics such as inorganic and organic ligands, pH, and water hardness will reduce the toxicity of metals through different chemical or physiological mechanisms. Increases...
Disciplinary Integration: The Solution
The objective of this paper is to encourage a careful review of the interactions between engineers and bioenvironmental scientists (biologists, ecologists, and ecotoxicologists) as they...
Review of Data Needs and Collection Technology
The quality - or pollutional effect - of urban runoff has not attained a societal level of importance sufficient to support understanding it, much less controlling it. The paper reviews...
