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...
Heppner, Oregon Flood Warning System: An Interagency Cooperative Effort
The flood warning system is a network of event-actuated precipitation and river level gages in two flash flood prone drainage basins of 44 and 6. 8 square mile areas. These basins enter...
Shoal Creek Flood Control Plan Austin, Texas
Following the devastating 1981 Memorial Day flood, a comprehensive and innovative flood control plan was developed and implemented for Austin's Shoal Creek Watershed. The...
Multi-purpose Stormwater Detention Facility Completed as First Phase of Englewood, Colorado, Flood Control Project
In 1980 the City of Englewood Urban Renewal Authority proceeded with planning for flood control improvements along Little Dry Creek. The selected plan includes capacity improvements for...
A Real-Time Flood Management Model for River-Reservoir Systems
A flood forecasting model has been developed for the Lower Colorado River Authority that can be used in a real-time framework to make decisions on reservoir operations during flooding....
Estimating Low-Flow Frequencies of Ungaged Streams in New England
Equations to estimate low flows were developed using multiple-regression analysis with a sample of 48 river basins, which were selected from the U. S. Geological Survey's...
A Filtering Approach to Flood Routing
Hydrologic river routing and hydraulic channel routing are in general use for flood routing. Both approaches use deterministic mathematical models and treat inflow and outflow hydrographs...
A Hybrid Model for Storage Routing Through Rock Dumps
Construction of permeable structures across stream channels results in temporary impoundment of flood waters upstream of such structures. This happens because the hydraulic conveyance...
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...
Drought Analysis in the Ohio River Basin
This study formulates the drought series, including drought occurrence time, duration, and deficit volume by the use of daily streamflows and a tracer level of one-half mean value. The...
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...
Impact of Temperature on Columbia River Winter Floods
During the course of an extensive study of the Columbia River drainage to evaluate a major levee system near Portland Oregon, it was noted that flood runoff produced by winter storms with...
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...
Sedimentation Impacts on a Pumpback Storage Facility
Concern over future sedimentation impacts at a proposed pump storage hydroelectric facility at Lake Francis Case on the Missouri River led to use of a numerical model to analyze lake hydrodynamics....
Automatic Calibration of Conceptual Rainfall-Runoff Models
An automatic calibration strategy applied to land and channel components of the National Weather Service River Forecast System is outlined. Aspects discussed include the objective function...
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...
The Wet Look
The collapse of the Schoharie Creek bridge drew attention to underwater inspection. Underwater inspection of bridges gives engineers a better understanding of the condition of the bridges....
Evaluation of Sediment Transport and Friction Factor Equations Using MOBED
Three sediment transport rate equations and the same number of friction factor equations for mobile boundary channel flows were evaluated using a mobile boundary flow model called MOBED....
Engineering a Corporate Statement
Frito-Lay National Headquarters, Plano, Tex., occupies a 218 acre site in a corporate office park that had been a cow pasture. It was unusual in having mature trees and a natural watercourse...
Sultan River Project Operation Study for the Sultan River Hydroelectric Project
The project will be operated to maximize energy production from the Sultan River within the operational constraints imposed by the water demand for the City of Everett and by the instream...
