A Lawyer's View of Engineers' Responsibility
When presented with a case involving damaged property, a lawyer typically will seek to determine the point of the failure and then work backwards in an effort to analyze each of the factors...
Litigation Support Investigations Involving Complex Flood Plains
This paper presents the case history of a devastating flood that occurred in a community located on a complex flood plain adjacent to a tidally influenced bay. Flooding resulted from cumulative...
Estimation of Urban Stormwater Quality
Two data-based methods for estimating urban stormwater quality have recently been made available - a planning level method developed by the U.S. Environmental Protection Agency (EPA),...
Instrumentation for a Dry-Pond Detention Study
A 12.3-acre, fully urbanized, residential land-use catchment was instrumented by the U. S. Geological Survey in Topeka, Kansas. Hydraulic instrumentation for flow measurement includes...
The Bureau of Reclamation in Transition
Recognizing and responding to the changing climate in water resources, the Bureau of Reclamation recently launched a massive effort to redirect the agency's traditional mission....
Design Depths and Velocities on Alluvial Fans
Under Federal Emergency Management Agency (FEMA) guidelines, flood depths and velocities on alluvial fans are determined by considering the probability of a given point on the alluvial...
Evaluating Flood Hazards on Alluvial Fans
In 1982, the Federal Emergency Management Agency (FEMA) developed a methodology for the determination of flood hazard zones and base (100-year) flood elevations on alluvial fans for administering...
Effects of Basin-Wide On-Site Stormwater Detention
The effect of basin-wide on-site detention of storm water runoff from developed areas is investigated to determine its effectiveness in reducing peak discharges in downstream portions...
Design and Evaluation of Storm Water Detention Facilities Using a Design Storm and Probable Maximum Storm
When designing a storm water detention facility, both a design storm (DS) and a probable maximum storm (PMS) should be considered. The DS is used to design the facility. The PMS is used...
Probabilistic Approach to Maintenance Scheduling
Maintenance has the purpose of prolonging the working life of equipment and of sustaining expected levels of performance and reliability. If equipment deterioration is construed as a probabilistic...
Probabilistic Maintenance Opportunities
The Bureau of Reclamation has instituted a number of operation and maintenance oversight activities to ensure that Reclamation and water-user operated projects are operated and maintained...
Scodie Canyon Flash Floods of 1984
This paper describes a unique thunderstorm and flood which occurred in Kern County, California in 1984. It describes the follow-up studies and method of implementation of building restrictions...
Alluvial Fan Flooding and Development Alternatives
The Federal Emergency Management Agency (FEMA) utilizes a methodology which examines the probability of an incised channel forming at any given location across the fan, in consideration...
Hydraulic Design for La Quinta Stormwater Project
An upstream detention basin was designed to trap debris and attenuate flows into Bear Creek Channel. The high velocity supercritical flow made a one side bank protection design for the...
Emergency Response to the 1983 Debris Flows Along Utah's Wasatch Front
The wet cycle experienced in Utah culminated in approximately one thousand landslide triggered debris flows caused by rapid melt of unprecedented snow accumulation in the Wasatch Mountains,...
The USDA Water Erosion Prediction Project
New generation water erosion prediction technology is being developed by the USDA Water Erosion Prediction Project (WEPP). The new technology is expected to replace the Universal Soil...
An Agricultural Watershed Environmental Study
The concerns of this study are the effects of soil and water conservation measures on a salmonid habitat for an agricultural watershed. The study includes an economic analysis in accordance...
Water and Sediment Yield in the Tucannon River
A site specific model for water and sediment yield was developed to estimate water quality aspects of the Tucannon River Basin. In this paper, the relation of water and sediment yield...
Channel Morphology and Habitat
Stream channels provide habitat for aquatic animals, such as fish and aquatic benthic invertebrates. Associated with the channel are near water habitats important to amphibians, reptiles,...
Kissimmee River: Engineering Approaches for Restoration
The Kissimmee River, located in central Florida, was channelized for flood control during the 1960s. Movements by environmental interest groups have produced strong sentiment to restore...
