Needed Social, Cultural and Design Changes to Successfully Manage Nigerian Surface Irrigated Projects
The aim of this paper is to illustrate the broad nature of problems associated with the faulty initial designs of water distribution network and irrigation methods and poor participartion...
A Method for `Warped Surface' Land Forming Design
Most approaches to land forming are based on a plane surface design which in some cases may result in prohibitive costs or excessive removal of top soil....
Bulk Stomatal Resistance in Operational Estimates of Evapotranspiration
General relationships for estimating canopy or bulk stomatal resistance and aerodynamic resistances of grass and alfalfa reference crops for use in the Penman-J.L. Monteith equation are...
Ultrasonic Flow Meter Testing
Six ultrasonic flow meters were tested in a hydraulics laboratory. Accuracies better than 2% were obtained with two transit-time meters on 14 inch diameter steel tubing. Poorer accuracies...
Stable and Environmental Channel Design
The Wildcat and San Pablo Creeks Flood Control Project is located in Richmond, California. Both streams flow through a highly urbanized area, periodically overflowing their banks and causing...
Computer Aided Hydraulic Design of Open Channels
Over a 10 year period, the computer program, WASURO, was developed by the U.S. Army Corps of Engineers District, Los Angeles (LAD), which utilized many of the criteria of the previously...
Power Formula for Open-Channel Flow Resistance
This paper evaluates various power formulas for flow resistance in open channels. Unlike the logarithmic resistance equation that can be theoretically derived either from Prandtl's...
Southwestern Drainage Litigation
In this paper, three technical sources of drainage litigation are examined. First, in the overall sparsely but locally densely populated Southwest, there is a severe lack of precipitation...
Design Depths and Velocities on Alluvial Fans
Under Federal Emergency Management Agency (FEMA) guidelines, flood depths and velocities on alluvial fans are determined by considering the probability of a given point on the alluvial...
Design and Evaluation of Storm Water Detention Facilities Using a Design Storm and Probable Maximum Storm
When designing a storm water detention facility, both a design storm (DS) and a probable maximum storm (PMS) should be considered. The DS is used to design the facility. The PMS is used...
Features of Flow in Slurry-Thickening Ponds
The study reported was undertaken to investigate the physical processes which come into play in settling-pond slurry thickeners and causes their behavior to deviate from those included...
Hydraulic Design for La Quinta Stormwater Project
An upstream detention basin was designed to trap debris and attenuate flows into Bear Creek Channel. The high velocity supercritical flow made a one side bank protection design for the...
Stochastic Streamflow Sequences for Reservoir Operation and Design
A stochastic streamflow model is adapted for risk methodology in the operation and design of reservoirs. The model is based upon the representation of the flood series as a Poisson counting...
Scour Downstream of the Straight Drop Spillway
Tests made to determine the effect of high tailwater and long duration flows on scour downstream of the straight drop spillway stilling basin are presented in this paper. Results are presented...
Federal Microcomputer Software for Urban Hydrology
The purpose of this paper is to describe the development, availability, and general use of selected urban hydrology microcomputer software developed by: U.S. Soil Conservation Service...
A Simulation Technique for Modeling Flow on Floodplains and in Coastal Wetlands
The system design is premised on a proven, areal two-dimensional, finite-difference flow/transport model which is supported by an operational set of computer programs for input data management...
Modeling of a Low Head Hydroelectric Project
In order to shorten the time to develop a hydroelectric project at the Corps of Engineers Hannibal Lock and Dam on the Ohio River for the City of New Martinsville, West Virginia, a turnkey...
Analysis of Spillway Failures by Uplift Pressure
Results of a model study to evaluate the development of uplift pressures beneath concrete chutes are presented. Two spillway failures are described to support the study results. Common...
Design and Performance of Earth Spillways
The U.S. Department of Agriculture's Soil Conservation Service has designed and administered construction of a large number of dams utilizing grassed earth-lined auxiliary...
Alternate Designs for the Sidewalls of Hydraulic Jump Stilling Basins
This paper discusses several alternate designs to replace the full height sidewalls of a type 2 U.S. Bureau of Reclamation stilling basin. The alternate designs that were investigated...
