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...
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...
Time Base of a Hydrograph
For design projects in water resources, a hydrograph is commonly used to determine the required flood volumes. The time base of a hydrograph is a crucial parameter in such studies, and...
Cleanup on a Large Scale
The San Gabriel Basin yields 200,000 ac ft of groundwater a year from 400 supply wells. This water makes up 95% of the Valley's water supply. Already 30% of the water pumped...
Sewer-Septic Tank Hybrid Promises Savings
Until recently the only options for sewage were the septic tank/leach field or conventional sewers. In some cases a hybrid of the two, called the septic tank/effluent drain, is less costly...
Irrigation Systems for the 21st Century
This book contains papers presented at the ASCE Irrigation and Drainage Division specialty conference, Irrigation Systems for the 21st Century, held in Portland, Oregon, July, 1987. Environmental...
Impact of Economic Factors on Development of the Lower Euphrates Basin in Turkey
The case of Lower Euphrates in Turkey represents fairly well the dynamic character of multi-purpose projects with respect to technological developments and changes in economic factors....
Determination of the Effects of Multiple Small-Scale Hydroelectric Projects on Resources in a California River Basin: A Matrix Approach
In 1983, Section 306 of the Energy and Water Appropriation Act required the FERC to conduct a comprehensive water resource analysis in the Upper San Joaquin River Basin, California. A...
U.S.-China's Cooperation in Unified Resource Development
This paper reports on activities between China and the United States involving exchange of technical expertise and project development. The paper focuses on how unified resource development...
HYPOS?Hourly System Hydropower Scheduling
HYPOS (Hydro Power Scheduling) is a modification of the program HYPO as presented at Waterpower 81. HYPOS is an interactive system which allows schedulers to assign hourly power generation...
Water Availability for Energy Development in the Upper Colorado River Basin
The Bureau of Reclamation is investigating, for planning purposes through hydrologic determination, the total allowable depletion level in the Upper Colorado River Basin. The Colorado...
Riverbank Stability and Monitoring at Grand Coulee Dam
The capability for hydroelectric power generation at Grand Coulee Dam was substantially increased following construction of the third powerplant in the mid 1970s. Increased river fluctuations...
Three-Dimensional Plotting in Dam Potentials
Hydroelectric development is important to many basins in the western United States. Topographical studies are normally used to arrive at sites to be chosen for further investigation of...
Lessons Learned From Examination of Membrane Roofs in Alaska
During 1984 and 1985 airborne infrared roof moisture surveys were conducted of membrane roofs at Army installations in Alaska. Many of these roofs were also visually inspected and cored...
Designing Marinas to Mitigate Impacts
The John Wayne Marina was permitted for construction only after certain design features were altered to accomodate major biological and water quality concerns. The moorage basin was relocated...
Sea Level Rise and Coastal Stormwater Drainage
Global sea level rise as a result of the greenhouse effect and the past trend and future projection on the rise are discussed. Potential problems associated with coastal stormwater drainage...
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...
Issues in Specifying Climate Forcing of Variability
Several issues arise in the specification of the role of climatic forcing of variability of water resources. The effects of human intervention must be removed so that the climate signal...
Agricultural Drainage Policy in the United States Department of Agriculture
Agricultural drainage policies in the United States Department of Agriculture (USDA) generally call for improving the root zone environment for crop production while protecting the resource...
Deferred Drainage?Prudent Policy or Tactical Folly?
The practice of deferring drains has not always worked out as planned. This is particularly true of large outlet drains such as the San Luis Drain in the Central Valley of California and...
