Excerpt from Storm Rainfall of Eastern United States, Vol. 5: Technical Reports This report sets forth the results of what is probably the most extended study of storm rainfall that has ever been undertaken. When an engineering examination of the Miami Valley was begun, immediately after the subsidence of the great flood of March, 1913, for the purpose of determining the best plan for preventing damage by future floods, an investigation of rainfall and runoff conditions was one of the first lines of attack. Although the 1913 flood seems to have been by far the largest that has occurred in this valley since its first occupation by white settlers a little over 100 years ago, it was soon apparent that the records of daily discharge of the Miami River going back only to 1892, and the local rainfall records of somewhat longer duration, afforded but a poor basis for the determination of the most probable size, frequency, and distribution of future floods. The magnitude of the interests jeopardized by floods justified the use of an elaborate system of protection works if simpler ones could not be devised; and the valley is so densely populated, the areas subject to flood damage so separated and diverse, and the conditions affecting the development of plans so numerous and complicated, that only an extensive and costly system could adequately secure effective regulation. To meet this intricate situation it was necessary to determine not only the largest flood that could ever possibly occur, but also, so far as possible, the frequency of all smaller floods which would cause damage.
