Faa Storm Water Program, W. H. Espey Jr., Raymond Rose, George I. Legarreta

United States Department of Transportation: Publications

United states Environmental Protection Agency (EPA) promulgated regulations in November 16, 1991 pursuant to the Clean Water Act in the issuance of National Pollution Discharge Elimination System (NPDES) permit application regulations for storm water discharge. These regulations concern certain municipal and industrial activities. Air transportation facilities are included in the industrial activity category. The EPA storm water regulations specifically target airport deicing operations as an industrial activity. These regulations may increase Airport Improvement Program (AlP) trust fund expenditures for storm water control improvements. The Federal Aviation Administration (FAA), therefore, initiated a storm water program to assist airport operators in complying …

Scour Evaluations Of Existing Bridges, Michael J. Fraher

United States Department of Transportation: Publications

The collapse of the Schoharie Creek Bridge on April 5, 1987 was a catastrophic instantaneous failure caused by scour of the bridge foundation. This particular collapse received wide media attention due to a home video of part of the collapse, the location on the New York State Thruway and the tragic loss of life. This particular collapse was not the first major interstate highway bridge failure attributed to scour of foundations. It is fair to say, however, that this was the event that finally brought stream stability and bridge scour issues to the attention of highway administrators and bridge engineers …

Magnitude Of The Scour Evaluation Program, Lawrence J. Harrison

United States Department of Transportation: Publications

Tens of millions of dollars have been spent over the years on Federal-aid highway system bridges damaged by floods. Nearly 500,000 of the 577,000 existing bridges within the National Bridge Inventory are over waterways. The screening of these bridges over waterways for scour susceptibility will be completed, for the most part, by October 1992. The Federal Highway Administration has established January 1997 as the completion date for the scour evaluations of all existing bridges identified as scour susceptible. A cost-effective means of determining the specifics of bridges with unknown foundations is not currently available. Pending the development of technology to …

Merging Field & Laboratory Bridge Scour Data, J. Sterling Jones, Peggy A. Johnson, Arthur C. Parola

United States Department of Transportation: Publications

Highway engineers are struggling with a major effort to assess and evaluate our nation's bridges for scour. Advanced technology is urgently needed to make a meaningful impact on this effort. This paper describes a need to focus laboratory and field research studies on a better understanding of the bridge scour processes.

An Evaluation Of Highway Flood Damage Statistics, Jennifer Rhodes, Roy Trent

United States Department of Transportation: Publications

Hydraulic events result in thousands of incidents of property damage each year. The U. S. Army Corps of Engineers estimates that annual damage averages over $2 billion (CaE, 1991). Federal, state, and local agencies have set up emergency assistance programs to help pay these unusually heavy expenses. Despite the detail of the policies regulating such programs, a comprehensive database describing the causes and consequences of flood losses does not exist. In an effort to obtain clear and consistent statistics on highway related damage, the disaster files of the Federal Highway Administration's (FHWA) Emergency Relief (ER) Fund and the Federal Emergency …

"Status Of Scour Instrumentation Development", Roy Trent, Ian Friedland

United States Department of Transportation: Publications

Improved understanding of scour and sedimentation processes near and at highway bridges is dependant on collecting reliable field data. Field data collection programs, however, have been hindered by inadequacies in instrumentation and measurement technologies. Through a coordinated program of research, the Federal Highway Administration (FHWA), State Highway Agencies (SHAs), National Cooperative Highway Research Program (NCHRP), and other agencies are working on scour instrumentation. Investigations are underway to develop a wide range of equipment types for many purposes and needs, e.g., portable equipment to be used by field crews during floods for scour inspection or measurement of scour processes; fixed equipment …

Risk-Costs For Scour At Unknown Bridge Foundations, G. Kenneth Young, Stuart M. Stein, Roy Trent

United States Department of Transportation: Publications

A risk method sets priorities for bridge foundation information gathering. Scour failure risk is the product of failure cost and the probability of failure. The method is based on data (much of which is subjective) in the National Bridge Inventory, NBI. Risk determines the ranking of bridges for foundation data gathering in support of scour evaluation; high risks could vanish if substantial foundations are discovered.

Flow Impingement Velocities, Snake River, Wyoming, Stephen T. Maynord

United States Army: Publications

Flow impingement, which occurs when approach channels direct flow into a bank line at large acute angles, results in flow concentration along bank lines, which creates large forces on bank material or bank protection. As part of studies conducted to determine the required riprap size for impinged flow, velocities were measured on the Snake River near Jackson, Wyoming. High velocities and steep water-surface slopes were observed at each impingement site.

Revised Hydraulic Design Of The Los Angeles County Flood Control System, Michael E. Mulvihill, Scott E. Stonestreet

United States Army: Publications

The US Army Engineer District, Los Angeles, recently completed a study regarding the adequacy of an existing flood control system in Los Angeles County. Results of this study indicate that the level of protection afforded by the system is as low as 25-year in heavily urbanized areas. The Corps of Engineers plans to increase the capacity in two mainstem channels, raising the level of protection to greater than 1OO-year, by constructing parapet walls on top of existing levees and modifying constrictive bridges. A physical model study will be conducted to aid in analysis of complex design problems and will provide …

Levee/Floodwall Freeboard Design For An Urban Flood Control Project, Daniel B. Pridal, Edward F. Sing

United States Army: Publications

A methodology for the design of levee/floodwall freeboard using evolving guidelines based on the concept of superiority is presented. A case study illustrating the application of the freeboard design guidelines to the Truckee Meadows Project is shown. The Truckee Meadows Project provides a 100 year level of flood protection through the Reno-Sparks, Nevada metropolitan area along an approximate ten mile reach of the Truckee River. Major features of the project include levees, floodwalls, channel modifications, bridge replacement or reconstruction, a detention basin, and drainage improvements. The project is presently in the Preconstruction, Engineering and Design (PED) Phase within the Sacramento …

Removal Of Extremely Low Levels Of Munitions In A Drinking Water Supply, R. Mark Bricka, Wayne Sharp

United States Army: Publications

Past military operations have resulted in the contamination of soils by chemical munitions such as RDX, HMX and TNT (contaminant description, page 2) . The migration of water through the soils can transport the contaminants into groundwater and contaminate drinking water sources . Many military munitions are known or suspected to be carcinogenic and, therefore, must be removed from drinking water .

Analyses Of Special Hazards And Flooding Problems In Tropical Island Environments, Robert C. Macarthur, Douglas L. Hamilton, Michael D. Harvey, Hudson W. Kekaula

United States Army: Publications

Data and results summarized in this paper show that development of urban projects and design of flood control works in tropical island catchments must consider clear water flooding as well as special hazards such as landslides, flow bulking, high sediment concentrations, mud and debris flows and flow avulsions. The needs for and methods to estimate peak flows, event volumes and the potential extent and depths of flooding during severe storm events in urbanizing tropical environments are described.

Contaminant Groundwater Interception - Rma, S. Paul Miller, William L. Murphy

This paper describes a pioneer groundwater interception and treatment system developed and evaluated at a major Army installation.

Hydraulic Risk Of Flood Disaster Reduction At Dams, Shou-Shan Fan

United States Department of Energy: Publications

Floods are major natural hazards, not totally predictable and manageable, at least at the present time. We believe that floods, no matter how violent, need not cause major damage. Loss of lives can be prevented and economic catastrophe minimized if a decision maker has accurate prior information on major flood characteristics, such as the magnitude and arrival time of the flood and its potential damages.

Final Environmental Assessment For Endangered Species Habitat Enhancement/Creation Along Tile Missouri River Main Stem System

United States Army Corps of Engineers, Omaha District

The interior least tern (Sterna antillarum) and the piping plover (Charadrius melodus) are federally endangered and threatened species, respectively, which nest on sandbars in the Missouri River. This nesting habitat has been decreasing in past years, at least in part due to vegetative encroachment. Vegetation is no longer regularly scoured from sandbars by heavy spring flows and/or ice, primarily because flows are regulated by the main stem dams. New sandbar creation is uncommon because the river carries less sediment and is no longer meandering along much of its course. Bank erosion still continues to supply sediment …
