Nonsteady Flow to Nonpenetrating Well
A nonequilibrium formula has been obtained to predict the nonsteady drawdown distribution near a cavity well discharging from a nonleaky artesian aquifer. A graphical method has been suggested...

Storage Coefficients from Ground-Water Maps
A method for determining the storage coefficient of an aquifer using piezometric contour maps is presented which is based on the transient ground-water flow equation simplified and reduced...

Underground Hot Water Storage Could Cut National Fuel Needs 10%
The possible conservation of waste heat by using it to heat water and then, subsequently, injecting the heated water into wells screened in aquifers containing saline water is described....

Properties of Intimal Layer and Adjacent Flow
The importance of the information on mechanical properties of the intimal layer and adjacent flow fields in studies of vessel wall permeability and pathogenesis of atherosclerosis is well...

Flood-Frequency Analyses with Prerecord Information
Monte Carlo experiments were performed on each of several procedures for treating prerecord flood information in flood-frequency analyses. The performance of each method was judged by...

Contaminant Transport to Deep Wells
The process of convective transport of a conservative contaminant to a deep partially screened pumping well overlain by a zone of contaminated water is described by analytical and numerical...

Direct Injection of Reclaimed Water Into an Aquifer
The changes in water quality that occur when reclaimed water is injected into a confined aquifer are being studied. The major objectives are: (1)To determine the quality changes; (2)to...

Mixing in Shallow Coastal Sea: Case Study
Two tracer studies were used to characterize mixing and tidal exchange in a New Jersey coastal sea. Several dredged channels and complex flow patterns due to islands and embayments cause...

Convective Contaminant Transport to Pumping Well
Travel time of a contaminant from the water table to a well screen, and its concentration at the well screen at given time intervals, can be determined through a radially symmetric, idealized...

Flow Factor Line Used in Storage Calculations
An article by the writer provided a graph called the Storage parameter curve witch could be used for arriving at a rough estimate of the attenuating...

Viscosity and Surface Tension Effects on Weir Flow
Weirs have been in use for a number of decades for the measurement of discharge in channels. The existing discharge relations for weirs predict the discharge reasonably well at high heads;...

Numerical Pumping Test Analysis in Unconfined Aquifers
A numerical model is presented which describes the flow towards an abstraction well in an unconfined aquifer. At each radius the conditions within the aquifer are described in terms of...

Bibliography on Discharge Measurement Techniques
The Task Committee's charge relative to flow measurement included a review of techniques available, the encouragement of research in flow measurement, and the preparation of a final report....

Land-Use Model for Service Area Projection
A new method for projecting future sewer service areas is developed, based on a model of land use and intra-urban migration behavior. The derivation of a partial differential equation...

Roughness Effects on Rectangular Free Overfall
For a rectangular free overfall, the end depth ratio (EDR) has been well connected with the main parameters using dimensional analysis. Using experimental results on three different roughnesses,...

ASCE and Nuclear Power Plants
A presentation is given by the President of the ASCE at the Second ASCE Specialty Conference on Structural Design of Nuclear Power Plant Facilities. An underlying interest of ASCE and...

Modeling of Health Care Delivery
A mathematical model has been developed to simulate the movement of patients from their residences to hospitals in the State of Indiana. The basic idea is that the behavior of patients...

Investigation of Two-Regime Well Flow
A mathematical method and a Galerkin finite element formulation are presented for steady two-regime flow toward wells in confined and unconfined aquifers. The model is verified by comparing...

Control of Salt-Water Intrusion by Recharge Wells
The present investigation involves study of the effect of a battery of recharge wells on control of salt water in coastal confined aquifers. In each investigation, the battery has a specific...
