Heat and Mass Transfer in Cold Regions Soils

The work upon which this report is based was made possible by a cooperative aid agreement between the U.S. Forest Service, Institute of Northern Forestry, Fairbanks, Alaska, and the Institute of Water Resources, University of Alaska. Contributions to this study were also made by the University of California at Davis and Ohio State University. The collection of winter data on pore pressures was made possible by a separate grant by the Office of Water Research and Technology (project A-053 ALAS)

Well Drawdown in Unconfined Acquifiers Under Non-Steady Conditions

(print) 21 leaves : ill. ; 28 cm.As a result of project (B-QO6-0HI0) a paper was published in the Water Resources Research Volume 5, No. 1, February, 1969. This research was supported by the Office of Water Resources Research, U.S. Department of the Interior through the Water Resources Center of the Ohio State University and is submitted as the final report.This study was supported in part by the Office of Water Resources Research, U. S. Department of Interior under Project B-006-0HI0The drawdown in a pumped unconfined aquifer can be analyzed by computer methods. The computer can give simultaneous solutions for flow in the saturated and unsaturated zone. The surface of seepage can also be included in the analysisIntroduction -- Basic Equations -- Computational Procedure -- Flow Problem Example - Gravity Well With Horizontal Replenishment -- Other Computational Considerations -- Illustrative Flow Cases -- Reference
