Download or read book Hydrologic Effects from Urbanization of Forested Watersheds in the Northeast written by Howard William Lull and published by . This book was released on 1969 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanization of forest areas tends to reduce interception, reduce infiltration and increase overland flow, reduce soil-moisture storage, reduce evapotranspiration, increase runoff, increase peak flows, and reduce water quality. annual maximum peak flows, annual hydrologic responses, and annual runoff were found (from actural streamflow records) to increase with progressive urbanization. the percentage of summer rainfall that appeared as runoff and the hydrologic responses were greater for partially urbanized watersheds than for mostly forested ones.
