New Evapotranspiration Crop Coefficients
Improved crop coefficients for various Pacific Northwest irrigated crops were developed for estimating crop evapotranspiration (ET) from estimates or measurements of reference ET. Reference...

Recovery in Large Diameter Wells
A closed-form approximate analytical solution for recovery in fully penetrating large diameter wells tapping a confined aquifer is presented. The solutions are also applicable for unconfined...

Synthetic Fabrics as Soil Filter: A Review
The fundamentals of fabric filters, their uses, design, longevity, strength requirements, and testing are reviewed and discussed. For unidirectional laminar flow conditions, particle retention...

Well Hydraulics in Vertically Heterogeneous Formations
Comparative analysis of time-dependent drawdown alterations caused by the heterogeneous properties of stratified formations is given based on solutions developed under different assumptions...

Ground Water Pumping from Shallow Axisymmetric Ponds
The hydraulic aspects of pumping from axisymmetric ponds, or large diameter wells, as a means of developing shallow, unconfined aquifers are investigated, and it is shown that pond storage...

Distribution and Use of Drainage Wells in Florida

If Your City's Well Water Has Chemical Pollutants, Then What—
Synthetic organic chemicals, especially certain solvents, are showing up in groundwater all over the U.S. and in many other industrial countries as well. These substances, some of which...

Four Options for Hazardous Waste Disposal
Landfills, land treatment, mine storage, and deep well injection are four options examined as solutions to the hazardous waste disposal problem. Statistics indicate approximately 40 million...

Unstable Turbulent Flow in Open Channels
Controversy on the determination of the friction factor, f, for turbulent flow in open channels of rectangular cross section has existed among previous investigators. A number of them...

Methane Gas Utilization from Landfill Site
The results are described of a case study of a gas extraction and utilization system located on a sanitary landfill site. The system includes the following: a 0.9-m-diameter gas extraction...

Legal Aspects of Subsidence Due to Well Pumping
Subsidence of land due to pumping of ground water is a relatively recent phenomenon. Early cases based on English common law held a person who pumped ground water was not liable for damage...

Economic Consequences of Land Surface Subsidence
Overdraft in the Santa Clara Valley ground-water basin caused land surface subsidence over an area of about 63,000 hectares with a maximum depression of about 3.6 meters between 1912 and...

Dual Recharge Well for Water Supply Stabilization

Perturbation Methods in Diffraction
In a technical note by Isaacson it is asserted that the usual perturbation method for approximating solutions to water-wave problems in the presence of solid boundaries brakes down at...

Embankments Through Cross River Swamp
The design, construction and performance of embankments across a deep clay flood plain are described, the construction involving a two-stage procedure with sand drains to aid consolidation....

Cation Transport in Packed Bed Reactor of Soil
A model of cation transport through a reactor of soil has been utilized which includes the processes of convection, dispersion, and cation exchange. Results from the model by finite differences...

Singularities in Darcy Flow Through Porous Media
Several types of singularities which threaten the integrity of numerical solutions occur in potential flow problems. The singularity at the tip of a cutoff wall is strong and cannot be...

Ground-Water Management with Fixed Charges
The problem of where to drill wells, how many to drill, and how to pump them in order to maintain low water levels in an excavation most economically is formulated as a fixed-charge problem....

Aquifers: Finite-Element Linear Programming Model
The efficient management of a confined aquifer with multiple wells under steady conditions is considered. Aquifer hydraulics is modelled by the finite element method, and the optimization...
