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...
Paleoflood Studies in Colorado
Paleoflood hydrology is the study of botanic, sedimentologic and geomorphic flood evidence remaining in a valley. Paleoflood studies in the Colorado foothills and mountains have been used...
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...
Rock Island District Hydropower
The paper discusses status of hydropower studies within the Rock Island District of the U. S. Army Corps of Engineers. It presents an overview of the low head hydropower studies on those...
Ruedi Dam Hydropower Project
The Ruedi Dam & Reservoir is owned and operated by the Bureau of Reclamation, U. S. Department of the Interior and is part of the Fryingpan-Arkansas transmountain diversion development....
Lemon Dam Hydropower Project
The Florida Water Conservancy District (District), the entity responsible for the operation of the dam and for repayment of the costs, had been interested in the hydropower potential of...
Small Hydropower Potential in Missouri
The hydropower potential of small head plants on the Gasconade River was investigated. Since, it is felt that small head plants will have less environmental impact, thus it will be more...
Design and Application of an Open-Loop Control System for Run of River Sites
This paper compares an open loop control system for variable geometry turbines to a closed loop system for fixed geometry turbines. The control systems were designed to operate three submersible...
Crooke's Falls Small Hydro: A Case History
The paper discusses the background, financing, licensing and other aspects of hydroelectric power plant development at Crooke's Falls, Colorado....
Hydropower on the Arkansas?A Non-Federal Development
In 1980, Arkansas Electric Cooperative Corporation (AECC) filed preliminary permit applications with the Federal Energy Regulatory Commission for developing the hydropower potential at...
Non-Federal Development at Corps Projects: Ohio River Division Experience
The paper presents the recent experience of the Ohio River Division of the Corps of Engineers (ORD) in non-federal development of the hydropower potential at existing Corps projects under...
Dolores Pumped-Storage Unit?A Case Study in Planning
The Durango Projects Office of the U. S. Bureau of Reclamation (Reclamation) conducted a pumped-storage investigation from 1981 to 1983 on a site in southwestern Colorado. This paper describes...
