Corps of Engineers Automation of Real-Time Water Control Management
Automation of real-time water control management activities has enabled the Corps to keep pace with an ever increasing workload in a time of fiscal constraint and reduced manpower. Where...
Flood Reduction Efficiency of the Water-Management System in Dade County (Miami), Florida
Two tropical weather systems, Hurricane Donna (1960) and Tropical Storm Dennis (1981), produced nearly equivalent amounts of rainfall in a 48-hour period south of the Miami (Florida) area....
Precipitation Analysis in Clark County, Nevada
The Clark County, Nevada Department of Public Works retained Black & Veatch in March 1985 to conduct a study of the Flamingo Wash and to recommend flood protection facilities,...
Stormwater Management in Kansas
This paper evaluates the current stormwater management practices of Kansas cities. This evaluation is based on a survey of all Kansas cities with populations over 10,000. Issues examined...
Design Storms for Urban Drainage
The characteristics of design storms for urban drainage are reviewed. There are indications that, under certain conditions, design storms produce runoff simulation results which are equivalent...
Outlet Structure Hydraulics
Current detention basin design procedure is to design the outlet structure for two or more return periods. This is sometimes done by combining weirs and/or orifices of various sizes and...
Uncertainties in Groundwater Transport Modeling
Using synthetic data from a hypothetical aquifer, the effects of data availability and data uncertainty were studied by the combined use of a parameter identification (PI) algorithm and...
A Robustness Constraint for the Analysis of Uncertainty
A sensitivity-based definition of system robustness is presented that can be formulated as a constraint within an optimization framework. The optimization framework permits the tradeoffs...
The Reliability of Treatment Systems
The purpose of this paper is to present the results of case studies of zero and first order reactor systems and an activated sludge treatment system consisting of a primary settling tank...
Computer-Aided Analysis of Treatment Plant Hydraulics
This paper describes software for the hydraulic analysis of water and wastewater treatment works. HADES (the Hydraulic Analysis, Design, and Evaluation System,) provides interactive analysis...
Flood Control, Water Conservation, and Urban Change
Los Angeles County has one of the largest, most complex and effective systems of flood control and water conservation facilities in the United States. It includes 14 major dams, 125 debris...
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...
Heppner's User-Friendly Local Flood Warning System
The Heppner, Oregon, local flood warning system uses state-of-the-art technology with event-initiated data transmission, real-time monitoring, and automatic evaluation and notification....
Verification of a Supply Reliability Model
Three versions of an analytical model for estimating the reliability of a water supply system including capacity components and small amounts of finished water storage are presented. Simplifying...
Modeling Reliability in Water Distribution Network Design
The component failures in a water distribution system include pipe breaks, pump failures, valve failures, storage malfunctions, etc. The reliability of these components has an effect upon...
Multivariate Modeling of Hydrological Time Series for Generation of Reservoir Operating Rules
A multivariate model and a disaggregation model are used in this study to generate annual and monthly time series of streamflow data for multiple sites. The parameters of the models are...
Optimal Weekly Operation of a System of Three Multipurpose Reservoirs
Marion, Council Grove, and John Redmond Lakes located in the Upper Neosho-Cottonwood River basin are an integral part of the State Water Marketing Program of Kansas. In addition to water...
Modeling to Generate Alternatives: A Review
Modeling to generate alternatives (MGA) is a species of multiobjective programming in which some relevant objectives and perhaps some constraints are deliberately left unquantified. The...
Integrating Policy Factors in Stream-Aquifer Models
One of the main issues appearing today in the field of water resources is the management of complex hydrologic systems consisting of surface streams and aquifers. The management problem...
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...
