Notes on sedimentation activities calendar year 1979

This report is a digest of information furnished by Federal Agencies on sedimentation investigations, both ongoing and planned. Included in the report are a review of important findings, new methodologies, new publications, laboratory and other research activities, and other pertinent information. The material is organized on the basis of the 21 water resources regions delineated by the U.S. Water Resources Council (WRC) for use in the national assessment (see figure 1). A listing by WRC region of stations at which sediment data have been obtained is given in table 3 of the appendix. Within each region, the stations are arranged according to their 8-digit hydrologic unit code. Stations for which the hydrologic unit code was not available are given at the end of the listing under "Miscellaneous." Also given in the appendix is an explanation of the column headings in the station listings, the code number and abbreviations used for State, county, and other areas (table 1), and the code for each organization reporting activities in this volume (table 2).
