Excerpt from Hydrologic Data for Experimental Agricultural Watersheds in the United States, 1976 Information on selected storm events includes (1) tabular data for antecedent rainfall and runoff, (2) data on rainfall intensity and runoff for the event and on accumulated depth of rainfall and runoff, (3) description of watershed conditions at the time of the selected events, and (4) plottings of runoff hydrographs and rainfall histograms. Newly established watersheds include descriptions of watershed physical characteristics, instrumentation, land management, graphs, maps and recommended area of application of the results. The first 11 publications in this series resulted from the cooperative efforts of several watershed research projects of the Agricultural Research Service and the editing staff in Beltsville, Md. Hydrologic data were summarized, arranged according to standardized formats, recorded on preprinted data sheets, and submitted to the editing office for final review, assemblage, and publication. A computer-oriented system, designed and developed by the Water Data Laboratory, is now used to produce camera copy for these publications. This is the ninth publication that has been compiled using the computerized system. Hydrologic data submitted from research projects, in digital computer form, are accepted by the system. The required data analyses and summaries are performed and the tabular listings and plottings are provided within and by the system. Narrative information is incorporated into the system as uppercase and lowercase alphameric data using computer compatible word-processing equipment. The format of hand compiled references (4-11) has been retained where practicable in the computer-compiled versions of the publications.
