Well Field Management Designed to Miminize Impact on Surface-Water Flow
Restrictions placed on the operation of a well field used for public water supply initiated an investigation to develop management techniques that would maximize utilization of the well...

Design Criteria for Detention Basins in Urban Drainage
Many communities require the use of detention basins in order to manage the increased runoff discharge in all newly developing watersheds. The authors have shown earlier that the typical...

The Storage Matching Technique of Detention Basin Design
In recent years, use of continuous rainfall - runoff simulation with historic rainfall data has become much more popular for the design of detention basins and reservoirs. While it may...

Flood Forecasting Using Local Resources
A dynamic wave flood routing computer program has been used to develop a flood forecasting model for a 5000 mi**2 watershed in lower Michigan. The modeled area covers over 200 miles of...

Real-Time Hydrologic Modeling
The Huntington District of the Corps of Engineers is currently using daily computer modeling for guidance in regulating all nine of its major river basins. Both pool elevation and flow...

Criteria for Spillway Design Floods
The procedures outlined in this paper only address the hydrologic safety criteria for spillway design floods. The recommended procedures are based on a careful identification of the social,...

Indemnification Costs in the Dam Safety Decision
The ASCE Task Committee on Spillway Design Floods has proposed safety criteria for three categories of dams. Category 1 dams are those with anticipated failure consequences so large and...

Hydrologic Runoff Modeling of Small Watersheds: The Tinflow Model
TINFLOW is a PC-based Geographic Information System (GIS) that utilizes the Triangulated Irregular Network (TIN) and associated data structures, together with a deterministic, finite difference...

A Flood Prediction Geographic Information System
The paper discusses a GIS that derives kinematic wave model parameters using stream network, elevation, and basin boundary data. Various approaches are being investigated for estimating...

Modeling Support for Stormwater Management
An innovative 'digitization' procedure has been developed and successfully utilized to accurately and economically prepare and manage the extensive amount of...

Muskingum Flow Routing Using Personal Computers
The paper discusses how tedious computations involved in flow routing can be easily implemented on Personal Computers. Parameter estimation and routing calculations for both linear and...

Utility Programs for DWOPER and DAMBRK
Time and computer resources greatly limit potential investigations and sensitivity anslyses. In order to facilitate modeling with the National Weather Service (NWS) programs DWOPER (Operational...

Safety Design Flood for Too Wide Creek Dam
This paper presents an example application of the procedure developed by the ASCE Task Committee on Spillway Design Floods for a dam on the Too Wide Creek. The example was developed from...

Changing Hydrology - The Middle Mississippi River
Observed daily flow and stage at major stream gages on the middle Mississippi River are numerically and graphically analyzed to quantify and illustrate the magnitude and seasonality of...

The Dallas Floodway Project
This paper explores the history of the Dallas Floodway project, past performance of the project under various flood conditions, recently updated hydrologic and hydraulic evaluations, and...

Monte Carlo Approach to Spillway Design Floods
This paper shows the use of a daily stochastic streamflow model for the calculation of the hydrograph for spillway design. Most of the literature related to the topic deals with the problem...

An Analysis and Comparison of Probable Maximum Floods with 10,000-year Frequency Floods and Maximum Observed Floods for Spillway Design
The use of deterministic probable maximum floods are supported in part by the conclusions of an Interagency Work Group formed to address the following questions: (1) Is it within the state...

Criteria for Selecting a Reservoir Routing Method
Results of an investigation comparing dynamic and storage reservoir routing applied in dam safety analyses are presented. Outflow hydrographs computed by these reservoir routing methods...

Time Base of a Hydrograph
For design projects in water resources, a hydrograph is commonly used to determine the required flood volumes. The time base of a hydrograph is a crucial parameter in such studies, and...

Fault-Tolerant Design for Data Acquisition and Flood Forecast Systems
An innovative fault tolerant flood warning system is currently being installed in the Passaic River Basin. The new system is designed to automatically tolerate the failure of major components...
