Effect of Storm Distribution on Watershed Stormwater Management
This paper presents a case study illustrating the effect of the selection of rainfall distribution pattern upon the ability of a calibrated rainfall-runoff simulation model to replicate...
A Storm Water Management Model for Grand Rapids, Michigan
In 1989, the City of Grand Rapids, Michigan, engaged Black & Veatch to conduct a comprehensive study of its combined sewer system with two primary objectives: (1) to relieve basement...
Integration of an ARC/INFO GIS with HEC-1
A hypothetical watershed was constructed to test the efficacy of using an ARC/INFO Geographic Information System to provide input for the U.S. Army Corps of Engineers HEC-1 hydrologic...
Levee Failure at Elba, Alabama
In March 1990, flooding resulted in levee failure at Elba, Alabama. The levee project was constructed in 1938 by the Works Progress Administration to provide protection to the city from...
Physical-Chemical Evaluation of Rainwater as an Indicator of Atmospheric Pollution in Some Zones of the City of Maracaibo, Venezuela
This study provided an evaluation of the presence of pollutants in the air over the City of Maracaibo by means of a physical-chemical analysis of rainwater collected in four zones of the...
Repair of Rainbow Project Unit Number Eight
This is a case history that discusses diagnosis and correction of a AC synchronous generator problem. The problem involved loss of mechanical integrity between the generator's...
An Alternative Approach to the Maximum Flood Concept
This paper outlines an alternative to the current approach for determining the maximum flood of river basins. The condition of the maximum flood is derived from the convolution integral...
Satellite Imagery Refines PMF Determination
This paper focuses on electromagnetic energy sensors, and describes how they are being used to determine the Probable Maximum Flood (PMF) for a drainage basin in Michigan. Remote sensing...
New Techniques and Data Sources for PMP
Testing has been conducted on new methods and storm data sources for the past two years with the purpose of providing more tools to dam owners for the assessment of probable maximum precipitation...
Colorado River Probable Maximum Floods
Upper limit design rainstorms (ULDRS) were developed for three locations in the Colorado River drainage above Hoover Dam. For each location, the rainfall magnitudes, spatial and temporal...
Design of Penstocks in Severe Earth Slide Locations
This paper deals with the problems of locating a penstock for a small hydroelectric plant at a site in Northern California that experiences considerable land movement during the rainy...
Overall Resistance Parameter of Flow Arising in the Catchment-Area of a Reservoir in Steep Land
On a small reservoir catchment in mountains, the basin storage S(t) during a flood was expressed in terms of the basin discharge Q(t) and the time-varying storage parameters K(t) and P(t),...
Erosion Potential of Pacific Basin Precipitation
Average annual erosivity (EI) values were developed using 20 years of hourly precipitation data from weather stations located on each of 10 Pacific Basin islands. Average annual erosivity...
Rainfall-Runoff Characteristics of Rangitaiki and Whirinaki Watersheds
The Rangitaiki and Whirinaki watersheds in New Zealand have considerably higher storage and infiltration rates than others in New Zealand. The Rangitaiki watershed is flat compared to...
Verification of Clark County Hydrologic Modeling
The Clark County Regional Flood Control District, which includes the Las Vegas, Nevada metropolitan area, has recently adopted hydrologic criteria which are intended to standardize the...
Reliability Assessment Method for Flood Forecasts
Peak discharge predictions produced by rainfall-runoff models and used by flood warning and preparedness agencies are subject to uncertainties in the input data, model parameters, and...
Conventional Storm Drainage Which Recharges the Groundwater
Since the demand for water is on the rise, more resourceful means of retaining and controlling the release of stormwater is needed. This retained stormwater may then be used for aesthetic...
Maintenance of Stormwater Management Facilities: Neglects in Practice
The Stormwater Management Facilities (SWMF) have become a required component of urban development projects in many parts of the country. In spite of differences in size, type, and physical...
Runoff Volume Frequency Estimation
An explicit formula is reported to express the volume of runoff resulting from a single rainfall event in terms of the catchment and rainfall characteristics. This formula is obtained...
Rainfall-Runoff Modeling in a Small Urban Watershed
Knights Branch watershed is located in Dallas, Texas, and it covers an area of about 5 mi2 (13 km2). Due to...
