Subsurface Drains Solve Groundwater Rise Problems
Four sub-surface drainage alternates were evaluated for lowering the rising water table. Horizontal gravity drainage system offered the best solution to the problem. Disposal of drained...
Spread Sheets for Irrigation and Drainage Projects
Land use planners as well as planners from other disciplines use overlays for site analysis but these are usually a qualitative display. Recently the advent of spread sheets coupled with...
Crop Yield Models Adapted to Irrigation Scheduling Programs
A crop yield model (CRPSM) was adapted to match the data obtained with typical irrigation scheduling programs. Daily soil water content was calculated from weather data, crop growth stage...
The Northwest Watershed Research Center, 1959-86
Hydrologic research has been conducted on the Reynolds Creek Experimental Watershed by the Agricultural Research Service for nearly 27 years. Some noteworthy instrumentation, developed...
Site Hydrology and Basin Design Using Spreadsheets
The Soil Cover Complex Method which was developed by the Soil Conservation Service is a commonly accepted method of evaluating site hydrology. The solution of this method is facilitated...
Effect of Length of Precipitation Record on Recharge Estimates
The effect of the length of precipitation record on groundwater recharge estimates is examined using data from eleven precipitation gages located on the Nevada Test Site. It is concluded...
Underground Drainage of Urban Runoff from Natural Depressions
A unique subsurface system was designed and implemented for draining such a natural depression in the City of West Lake Hills, Texas. This subsurface drainage system uses a part of the...
A Burning Wasteland Reclaimed
Until recently the PJP Landfill exemplified what can happen when uncontrolled and illegal dumping goes on for many years. Now it is an example of what innovation and imagination can do...
Preliminary Design and Construction Plan for an Ocean Wave Energy Conversion System
A preliminary design and construction plan for a prototype wave energy conversion system is described. While the design methodology and construction procedures are intended for generic...
Selection of Small Hydro Project Sites
In the course of studying nearly forty areas in Peru to identify possible sites for small hydro development and in order to select the best in each area for detailed design, the Authors...
Evaluation of Small Hydropower Sites in Ghana, Africa
Six potential small sites and one mini site under construction were visited. Two additional potential sites were identified from map studies. Flow duration studies indicated that with...
Developmental Changes Due to Site Investigations
The Winooski Hydroelectric Company of Montpelier, Vermont is conducting the reconstruction of Dam #8 on the Winooski River in East Montpelier, Vermont. Unprecedented eminent domain proceedings...
Thailand Micro/Mini Hydroelectric Project
The Royal Thai Government is attempting to systematically develop economically attractive indigenous hydropower resources through the Micro/Mini Hydroelectric Project. Initially six experimental...
Phased Pumped Storage Planning and Site Evaluation
A phase process of site evaluation provides for an efficient use of resources while supporting the necessary level of detailed investigation. This paper describes the phased siting process...
Methodology for Optimization of Cascade Small Hydro
An accurate classification of small hydro sites is introduced. Class 'C' small hydro developments utilize favourable topographical and hydraulic gradients along...
Financing Hydro Projects
STS Consultants, Ltd. is a consulting engineering firm with expertise in the Hydraulics/Hydrology area. Boulevard Bank is a major commercial bank in Chicago, Illinois. This paper elaborates...
Development of the Standardized Francis Turbine
Initial machine selections to address higher head sites included small custom Francis turbines and standard pumps running in the turbine mode. As the former proved too costly and the latter...
Computer Aided Design of Small Hydro Turbine
The paper discusses a system for producing custom designed turbines which are attractive in price and delivery, retaining the advantages of customization. A computerized program is being...
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...
