Abstract

Man can alter several facets of the hydrologic cycle appreciably. Those facets most easily altered are related to vegetative cover and surface geometry either on the land or in the drainage system. Changes brought about by man affect surface runoff and base flow, timing and peak discharges of flood flows, and water yields. Cover changes and more efficient drainage systems increase sediment delivery to streams. This paper attempts to define evidence of changes, and to comment on our present understanding of the extent of changes.
