Report of Committee on Ground Water, 1945–1946

The principal activity of the Committee during the year was the arranging and presentation of a symposium on methods of estimating ground‐water supplies. The response was gratifying and resulted in the presentation of 11 interesting papers at the 1946 meeting. The report of the Subcommittee on Permeability by C. E. Jacob, Chairman, is given as Appendix A. At a meeting of the Executive Committee of the Section of Hydrology in June 1946, this Subcommittee of the Committee on Ground Water was changed to the Committee on Permeability of the Section of Hydrology, with Jacob continuing as Chairman. This will give the new Committee much greater latitude in dealing with a subject which is of concern to several of the Research Committees.
