Changes in Stream Regime following Reforestation and Erosion Control Works

A study was made on the influences of reforestation and erosion control on a devastated watershed on the stream regime by the analysis of hydrological data from a paper mentioned below, Tennessee Valley Authority: Reforestation and Erosion Control Influences upon the Hydrology of the Pine Tree Branch Waterhed-1941 to 1960-, Tennessee Valley Authority 1962 When erosion control works were executed and successively reforestation with pine tree and others was practiced on a experimentral denuded watershed, the yearly total amount of direct runoff decreased and on the cotrary the one of base runoff increased and consequently streamflow through the year was made even, while both the annual runoff and it's percentage to annual precipitation decreased. And the amount increased of base runoff showed a decreasing tendency from around ten years after erosion control works were executed, it is presumed that is related to the growth of planted trees.Article信州大学農学部演習林報告 23: 165-179(1986)departmental bulletin pape
