It presents a detailed description of the watersheds, instrumentation, and procedures employed in the collection and analysis of data from runoff studies in Wisconsin. The author outlines the area to which the information presented can be applied if proper care is exercised in evaluating watershed characteristics. The book presents data for a group of the most intense storms on each of the watersheds and typical hydrographs indicating the effect of cover and antecedent moisture on rates of runoff. It outlines briefly the methods of analysis, presents recommended rates of runoff, from small agricultural watersheds, to be used in the design of conservation structures, and includes a typical flood distribution graph for the engineer's use in computing reductions in peak runoff rates. The author's insights on the main subject show that peak rates of runoff from small areas are of very short duration, thus making small amounts of storage effective in reducing these rates, and that the large differences in runoff from pastured and cultivated watersheds are due to the ability of the soils in this area to absorb large amounts of rainfall of high intensity when the surface is protected by good vegetative cover. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
