Mathematical Modeling of Compound Channel with High Sediment Concentration
The mathematical model for erodible channels, FLUVIAL-12, has been extended to simulate the fluvial processes in the lower reach of the Yellow River in China. Fluvial processes in the...
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...
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...
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...
Comparison of Vertical Velocity Measurements in the Great Lakes Connecting Channels with Theoretical Profiles
Vertical distribution of velocities was measured with an upward looking acoustic Doppler current profiler in the upper St. Clair River during November 1984 - April 1986 and the Detroit...
Hydrograph Timebase
Based on the study of a large number of hydrographs, a graphic solution is presented whereby the length of the hydrograph timebase can be directly read from the proposed graphic solution...
A Measure of Reservoir Efficiency
The notion of reservoir efficiency is defined for a water supply reservoir operated according to the standard policy, that is, one where the release is constant whenever physically possible....
The Life and Science of R. A. Bagnold
The purpose of this paper is to highlight and honor the exciting life and many significant contributions made by Brigadier Ralph A. Bagnold to our understanding of hydraulics and sediment...
Urban Drainage Calculation Limits for Small Areas
This paper discusses the selection and application of hydrologic techniques in the design of stormwater facilities, with particular emphasis on the selection of hydrologic procedure for...
River Sedimentation
This paper discusses Chapter 4 of the U.S. Army Corps of Engineers Engineer Manual of Sedimentation Engineering. The chapter identifies potential river sedimentation problems, associates...
The BRANCH Model and the Segara Anakan Study
The Lower Citanduy Irrigation Project in Central Java, Indonesia drains through the estuary called Segara Anakan. Due to sediment accretion, the lagoon is filling. With erosion problems,...
Estimation of Uplift Pressure in Cracks in Concrete Gravity Dams
This paper presents an analytical solution to predict uplift pressures in cracks in concrete gravity dams. It is shown that drainage systems are effective in reducing such pressures....
Sediment Survey of Lake Powell
The 1986 Lake Powell Sediment Survey documented the present storage-elevation relationship and loss of storage from sediment accumulation since the reservoir began filling. From the calculated...
