INFORMATION - Type curves for the solution of single-boundary ground water problems. UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY WASHINGTON, D.C. 20242 November 15, 1972 4300 5016 GROUND WATER BRANCH TECHNICAL MEMORANDUM NO. 73.03 Subject: INFORMATION - Type curves for the solution of single- boundary ground water problems. Ground Water Branch Technical Memorandum No. 73.02 announced availability of a supply of type curves to a scale of three inches per log cycle for the solution of single-boundary ground water problems. In addition, we call attention to Professional Paper 708, entitled "Ground-Water Hydraulics," by S. W. Lohman, published in 1972, which includes the type curves of Stallman at a scale of 1.85 inches per cycle. Log paper to this scale is available on the market (such as K & E 46-7522). Explanation of the relatively simple method devised by Stallman for the solution of single- boundary problems involving either a source or a sink is given on pages 59-61 of Lohman's paper.
