Application of the New SCS Time of Concentration Method
The second edition of the Soil Conservation Service (SCS) TR-55, published in June 1986, introduces a new method for calculating the time of concentration for storm runoff flowing through...
Some New Snyder Type Coefficients for Small Watersheds
Data collected on the Goodwin Creek watershed has produced a continuous hydrologic record from 37 rain gages and runoff record from 14 runoff stations within a drainage area of 8. 26 sq...
Flood Hydrology Modeling: U.S. Virgin Islands
To develop a consistent basis for evaluating existing flooding problems and for planning activities to reduce future flood damage, a watershed modeling project was initiated by the Government...
A New Method for Synthesizing a Six Hour Unit Hydrograph
A new methodology was devised that would use readily available basin physical parameters for the determination of unit graphs in undeveloped and ungaged areas. Rather than using small...
The Contribution of Local Area Management Teams Under Severe Environmental Conditions
This paper outlines a Westinghouse managed turnkey hydro electric project located in remote southwestern Wyoming near Kemmerer. The dam provides watershed control for the Hams Fork River,...
Estimating Climate Change From Hydrologic Response
In the eighty-one hydrographically closed basins within Nevada many large lakes developed during the pluvial climate of the Pleistocene. Pluvial lake area and tributary basin area have...
Studies of Long-Term Water Losses
The water-loss time series are formulated for the studied watersheds in the Ohio River Basin through the use of the law of water balance to the system inputs and corresponding outputs....
Relative Landslide Susceptibility in Davis County, Utah?A Multivariate Approach
The complex distribution of soil properties makes prediction of slope stability extremely difficult in these mountain watersheds. The need to assess these watersheds for their susceptibility...
America's National Forests: Our Ultimate Water Source
National Forest System lands in the western United States make up 21 percent of the total land area but yield over 55 percent of the region's streamflow and provide more than...
A Customized Database Management System for Watershed Modeling
When large watershed areas are being studied and continuously monitored, it is desirable to create a database management system (DBMS) that provides the necessary capability to build and...
Meadow ET in the Bear River Basin of Utah, Wyoming and Idaho
This study was begun in 1982 to assist the Bear River Commission in their statutory obligation of determining a duty of water under the Bear River compact. The study involved installing...
Sedimentation Problems of the California Aqueduct
The California Aqueduct crosses the alluvial fans of many intermittent streams on the west side of the San Joaquin Valley. At two sites where watershed sediment yields were underestimated,...
Solving Stormwater Drainage Problems Through an Area Drainage Master Study Program
The Flood Control District of Maricopa County, Arizona, is the floodplain and stormwater management agency for the most densely populated county in the State. A major new tool being used...
Regional Detention Basins as a Flood Control Solution
Through engineering studies the Harris County Flood Control District (HCFCD) has identified a feasible regional flood control project which can be constructed with local funding and would...
Prediction of Sediment Yield for Southern California Watersheds
The objective of this paper is to present a scientific method based on multiple linear regression analysis between the sediment yield per square mile and a number of physically realistic...
Analysis of Alluvial Fan Flooding
Alluvial fans are estimated to cover approximately one third of the land area in the southwestern United States. Because of their relatively gentle slopes and well draining characteristics,...
Unique Flood and Drainage Problems in Los Angeles
Storm drainage for the coastal cities has to traverse highly used sandy recreational beaches. Due to new requirements on the construction of storm drains to the ocean, a beach outlet has...
Owens Valley, California Basin Management to Meet Both Water Resources and Environmental Goals
The City of Los Angeles imports over 60 percent of its water supply from the Owens River Watershed as part of the resources used in serving 3. 5 million people. As part of this operation,...
Ecological Impacts of Sediment Transport to Tropical Reservoirs
Sediment transport and siltation influence both the longevity and ecology of tropical reservoirs. The sediment load to these systems is typically seasonal and affects ecological processes...
PC-RUNOFF and dBASE III for Stormwater Data Management, Planning and Design
A version of the RUNOFF Block of the Stormwater Management Model (SWMM) has been extensively revised for the Microcomputer Stormwater Simulation Manager (MSSM). In addition, PRERUN, a...
