Evaluating Spillway Adequacy
More than a third of all dam failures are caused by overtopping. Equipment malfunctions or operations errors are sometimes to blame, but the principal cause is inadequate spillway capacity....
Urban Development on Alluvial Fans
An increasing number of developments has been planned in areas subject to flood hazards. To protect developments from flood damage and to prevent accumulated negative effects on floodplains,...
Quantitative Risk Assessment and Technology Transfer: Software Developments
A risk-based adaptation of the hydroeconomic model for estimating the expected annual damages of floods is presented in a spreadsheet environment. The model demonstrates how commercially...
Optimal Flood Warning Threshold: A Case Study in Connellsville, Pennsylvania
A methodology for selecting an optimal flood-warning threshold has been developed by Haimes et al. (1990). The probabilistic evaluation of a forecast system coupled with a stochastic dynamic...
Influence of Irrigation on Subsurface Drainage
The influence flood irrigation has on drainage effluent in terms of discharge rates and water quality was analyzed at an artificially drained alfalfa field in Fallon, Nevada. Immediately...
Ecuador?The Lower Guayas Flood Control and Drainage Project?A Case Study
The Government of Ecuador (GOE) invited the World Bank in 1975 for a general review of the rural development in the country. One of the main findings of a Bank mission was the importance...
Aldicarb Transport in the Coastal Plain of N. C.
The pesticide aldicarb is extremely soluble in water which causes it to be mobile in ground water. A field study was conducted to monitor the fate of the pesticide aldicarb in a poorly...
Calculation of Runoff from Rainfall Using NURP Data
Peak runoff flows and flood hydrographs are important elements in the design of drainage and flood-protection structures. The validity of methods for predicting peak flow from rainfall...
Cloud Seeding: The Engineering is Done, but What About Social Impacts?
As engineers, we tend to focus on the technical aspects of cloud seeding, and may neglect important social aspects or potential side effects. Often people in the target area are more concerned...
Appropriate Technology for Flood Warnings
Computers can help protect cities and other developed areas by enhancing flood warning systems, but smaller communities may not be able to take advantage of their sophistication. The Corps...
Hydrologic Investigation of the April, 1983 Flooding in New Orleans, Louisiana
During the rainstorm of April 6-7, 1983, a shell ramp was constructed over State Highway 406, closing the relatively shallow depression formed by the roadway passing over the levee which...
Assessment of Derived Flood Frequency Distributions
Derived flood frequency distributions based on the geomorphologic IUH are evaluated in this work. Two existing approaches, the methods of Hebson and Wood (1982) and Diaz-Granados et al....
Two-Dimensional Hydraulic Analysis of the Owensboro Bridge and Approaches
The Kentucky Transportation Cabinet, Department of Highways, is working with the Indiana Department of Transportation and the Federal Highway Administration to plan, design, and construct...
Dry Creek Watershed Flood Control Plan: A Case Study
This paper describes the development of the Dry Creek Watershed Flood Control Plan. This study was conducted to quantify the extent of the existing and future (buildout) drainage problems...
Savannah International Airport Environmentally Minded Stormwater Master Planning
The proposed Savannah International Airport expansion required a coordinated effort between engineers and environmental scientists to develop a stormwater management plan which would utilize...
Trickle Channel Rehabilitation
Perhaps the primary factor driving the need for trickle channels is urban development. Rural streams in the region display a hydraulic stability and vegetative cover that is resilient...
When Sewer Rehab Doesn't Stop Basement Flooding
The western half of Wilmette, Illinois, is served by separate sanitary sewers. Constructed in the late 1920's, this separate sewer system was among the first installed in northeastern...
The Challenge of Kissimmee River Restoration
Between 1962 and 1971, the Kissimmee River in central Florida was channelized by the Corps of Engineers as part of a flood control project. Channelization has resulted in degradation of...
Hillsboro Basin Surface Water Management Model
This study presents the results of the hydrologic and hydraulic analysis of the 103-square mile Hillsboro Basin located in South Florida. The purposes of the project were to develop a...
BRASS Modeling of Lo?za Reservoir, Puerto Rico, for Sediment Management Operations
Loiza reservoir, the principal water supply for metropolitan San Juan, delivers 3.5 m3/s (80 mgd) to the Sergio Cuevas filter plant. Sedimentation...
