Optimizing Drain Spacing and Depth Using Steady State Equations
A method is developed for minimizing the total cost of establishing relief drains by choosing appropriate depth and spacing of the drains. Solution graphs are presented for a wide range...
Gully Incision Prediction on Reclaimed Slopes
An investigation was conducted to estimate the potential of gully intrusion into reclaimed waste impoundments. A series of eight reclaimed impoundments exhibiting gully intrusions were...
Coupling Free Vortex Energy Dissipation with Sediment Control
The paper reports on studies showing that sediment control down to the abrasive limit of 30 micron sand and energy dissipation can be achieved simultaneously with a Teacup free vortex...
Applied Hydro System Operations Models
The paper discusses computer simulation of system operations. Computer programs that simulate operations through future time periods on hourly, daily or monthly time periods are routinely...
California Water Project Operation
The California State Water Project (SWP) is operated and managed using state-of-the-art operations research and optimization techniques. Medium- and long-range studies for the operation...
A Proposed Desilting Reservoir System in Taiwan
The paper discusses the design of a desilting system for Nanhwa reservoir, in which the reservoir is divided into two bays; water flows into the forebay for sedimentation and then over...
Routing Comparisons in Natural and Geometric Channels
A method of establishing composite geometric cross section shapes hydraulically similar to natural cross sections with flood plains is proposed. The method is based on the nondimensionalized...
Toe Drain System?Barr and Milton Reservoirs, CO
The purpose of this paper is to describe the design and construction of toe drains in difficult soil conditions for two 70 plus year old dams in Colorado using a unique toe drain installation...
Application of a Stochastic Hydrology Model
This paper presents the development and application of a multi-site, multi-season stochastic hydrology model for the Sacramento Valley portion of the Central Valley of California. The...
Water Management of the Tenn-Tom Water
In December 1984 the final segments of the Tennessee-Tombigbee Waterway were completed. The Waterway connects the Tennessee River to the Gulf of Mexico at the City of Mobile. The total...
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,...
Sedimentation Processes in Hydrosystems, Numerical-Empirical Modeling
This paper presents the results of a newly developed computer simulation model for studying the sedimentation processes in a variety of hydrosystems. The most effective numerical methodology...
Sedimentation in the All-American Canal
During the planning for the All-American Canal, by the U. S. Bureau of Reclamation as part of the Boulder Canyon Project, works were designed at the head of the canal to remove between...
Emergency Flood Management, Salt Lake City, Utah
This paper discusses Salt Lake City's response to the floods of 1983 and 1984. Peaks during these years were very high with historic records being set in both years. Management...
Use of Continuous Simulation Versus the Design Storm Concept for Water Quality
The validity of the design storm concept has been challenged by several investigators since the development of computer simulation models. Of particular interest are the studies that compare...
Estimation and Inference in the Inverse Problem
The estimation of groundwater flow and mass transport parameters is approached via maximum likelihood. Confidence intervals and hypothesis tests as well as the asymptotic properties of...
Mixed Solute Interactions in Groundwater Systems
Research results are presented from a study examining the competitive sorption effects of two organic chemicals, para-dichlorobenzene and 2,4-dichlorophenol, to solids from the Cohansey...
Air-Water Oxygen Transfer at Spillways and Hydraulic Jumps
Dissolved oxygen measurements are reported for seven spillway structures in the vicinity of Minneapolis, Minnesota, corresponding to 27 individual surveys. The surveys are taken during...
Gas Transfer and Secondary Currents in Open Channels
Laboratory flume experiments on water-wide controlled gas transfer, such as reaeration, are described. The experiments indicate that gas transfer is a surface renewal process, well described...
Chlorination of Wastewater Treated by Overland Flow
Results are presented from an investigation of the efficiency of three chlorination schemes used for the disinfection of municipal wastewater treated by overland flow. In experimental...
