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

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...*
