Homeowner Decision Making in Public Water Supply
Homeowner decisions regarding the connection to a public water supply in urban fringe areas suggest that too few connections and low initial consumption per capita are very real possibilities....

Water Spreading and Well Field Water Supply System

Spatially Varied Flow over Side-Weirs
An experimental investigation of the flow over sharp edged side-weirs in rectangular channels is reported. The experiments cover subcritical and supercritical flow regimes with weirs of...

Flow over Rounded Spillways
Beginning with a condition necessary for irrotational flow, a reasonably simple solution has been obtained for the flow over round-crested spillways. Additional assumptions were that the...

Basin Recharge of the Ogallala Aquifer
Ground-water recharge basins were tested to determine the feasibility of percolating surface water to the Ogallala Formation in the Texas High Plains. The basins were excavated into porous...

Dispersion from Recharge Well
The dispersion of waste water from a recharge well is studied. The well is situated in a confined aquifer through which there is a natural uniform flow. The convective-dispersion equation...

Volume Weight of Reservoir Sediment in Forested Areas
Samples for the determination of the volume-weight ratio of deposited sediment were collected from small sediment-retention reservoirs in a number of forested watersheds in Idaho during...

Seawater Intrusion Extraction Barrier
An experimental extraction-type sea water intrusion barrier was tested near Oxnard in Ventura County, California, to develop information on halting intrusion in the area and in other areas...

Gravitational and Dispersive Mixing in Aquifers
Analytical techniques are developed to describe the mixing between two fluids of different density in a confined aquifer, in which one fluid is introduced to the aquifer by well recharge....

Finite Element Analysis of Flow Toward Artesian Well
The purpose herein is to present a finite element method for analyzing unsteady flow toward a partially penetrating artesian well. The method can be applied to cases involving either an...

Computer Analysis of Flow toward Artesian Wells
The purpose herein is to present a finite difference method programmed for a high-speed computer, for the analysis of unsteady flow towards fully and partially penetrating artesian wells....

Unsteady Drawdown in Well Groups
The unsteady drawdown response has been studied for a variety of well groups which are arranged in a two-line or rectangular array. The individual wells are assumed to fully penetrate...

Artificial Ground-Water Recharge by Means of Wells in Israel
Artificial recharge activities in Israel have become an indispensible component of the national water management program. Water quantities recharged by means of wells amounted in 1967-1968...

Development of Wells Hydroelectric Project
The low rock elevation was used to advantage by the development of a nonconventional design where the turbines were deeply submerged such that spillway openings could be located above...

Structural Design of Wells Hydrocombine
A new design concept for a hydroelectric project has been developed, combining powerhouse, spillway, fish facilities, and switchyard into a single structure called Hydrocombine. Hydrocombine...

Wells Hydroelectric Project Fish Facilities
The development of the fish passage and fish spawning facilities for the Wells Hydroelectric Project is described. Because the spillway and powerhouse are combined into a single structure...

Construction and Operation of Wells Dam
The construction and initial operation of the $202,000,000 Wells Hydro Electric Project on the Columbia River is described. A unique structured arrangement, known as Hydrocombine, forms...

Steady Drainage of Layered Soils: II, Nomographs
This is the second of two papers on steady drainage of layered soils. In the first paper, the theory was developed; in this paper, the drain spacing equations for the two-layered and three-layered...

Rational Design of Well Screens
Design of well screens has been based on empirical considerations. Equations describing the hydraulics of flow of water into well screens from the aquifer are developed which take into...

Computer Analysis of Free Surface Well Flow
A mathematical analog of immiscible multiphase well flow, considering three compressible fluids—two liquids and one gas—is solved with fully implicit finite differences. A Newton iteration...
