Risk Analysis and Management of Natural and Man-Made Hazards
The third Engineering Foundation Conference on Risk-Based Decisionmaking titled Risk Analysis and Management of Natural and Man-Made Hazards was held in Santa Barbara, California on November...
Cross Shore Variations in Heavy Minerals in Beaches of the Barrier Dominated Southeast Atlantic Coast
Cross shore beach sample sets from 102 locations along the barrier dominated Atlantic coast from Kitty Hawk, North Carolina, to Palm Beach, Florida were studied to determine if there were...
Protecting Undeveloped Barrier Islands?A Florida Case Study
Although most of Florida's large barrier islands have been partially or fully developed and their natural resource values jeopardized, several smaller islands along the coasts,...
Coastal Barrier Island Management in Florida
Coastal barriers in Florida have experienced the brunt of the state's rapid population growth. Excessive development of these environmentally sensitive areas has destroyed...
Coastal Barrier Resources Act Report to Congress
The Coastal Barrier Resources Act (CBRA) of 1982 established a system of 186 coastal barriers along the U.S. coasts of the Atlantic Ocean and Gulf of Mexico, and prohibited within this...
Environmental Risk Assessment at a Gas Utility
Over the past 10 years, Southern California Gas Company (SoCalGas) has developed an environmental risk management program to mitigate or eliminate the potential health risks to employees,...
Digester Gas Resource Recovery at Phoenix, Arizona
Until July 1986, the digester gas produced at this 150 million gallon per day facility, in excess of what was utilized for heating anaerobic digesters was flared. In 1983, a feasibility...
Economic Impacts of Storm Sewer Design Criteria
This paper discusses the selection of storm sewer design criteria and the resulting economic impacts. Using the Rational Method for calculating design flows, an investigation was made...
Flood Warning Using Wide-Area Computer Networks
Wide-area computer networks are being used with increasing frequency to improve regional response to flood events, coordinate efforts between agencies and communities, and to improve flood...
Predicting Human Instability in Flood Flows
The delineation of high flood hazard zones within a flood plain is usually independent of the parameters that constitute a life threatening situation. In order to define human instability...
Statistical Frequency Analysis of Flood Records
The U.S. Geological Survey, like other Federal agencies, uses Hydrology Subcommittee Bulletin 17 for guidance in statistical frequency analysis of flood records. This paper describes the...
Regionalization of Flood Characteristics
Regionalization procedures are used to transfer flood characteristics from gaged to ungaged locations. These procedures are an extension of the gaging network that allows planners and...
Urban Flood Frequency and Hydrograph Analysis
A set of seven-parameter regression equations was developed for estimating flood discharges at ungaged areas. The regression equations can be used to estimate urban flood discharges throughout...
Plans for National Flood Frequency by Microcomputer
Work is underway on a planned microcomputer program that will include about 1500 prediction equations for 214 flood regions of the United States and Puerto Rico. The program will include...
Effects of Vegetation on Floods at Four Arizona Sites
Four examples show the effect of vegetation on stage, discharge or frequency of floods. An 8-year growth of trees on the streambed at site 1 increased channel roughness enough to cause...
Models vs. Methods in Urban Drainage Calculation
This paper summarizes the findings of a recent study at Penn State aimed at recommended hydrologic techniques for small developing watersheds. The specific desk-top methods investigated...
Estimating Urban Flood-Frequency Characteristics
Methods in use by the U.S. Geological Survey to estimate flood-frequency characteristics for urban watersheds are compared with estimates based on the Soil Conservation Service TR-55 model....
Urban Watershed Data for the United States
The contents of an urban watershed data base compiled for a national urban flood-frequency study by the U.S. Geological Survey are described. The data base includes information for 269...
Joint Probability Calculation of Storm Depths
A methodology is presented to estimate exceedance probabilities of rainfall depths over large areas using joint probability. The joint probability estimate combines the frequency distribution...
