Watershedmanagement--1lChapter 3 Soil erosion and its control3.1 Introduction? Geologic erosion is the erosion undernatural or undisturbed condition. It iscalled normal erosion or natural erosionalso. Accelerated erosion is the increased rate oferosion over the geologic erosion broughtabout by human's activity3of15

It is called normal erosion or natural erosion also. • Accelerated erosion is the increased rate of erosion over the geologic erosion brought about by human’s activity. Watershed management- 11
Watershedmanagement--1lChapter3 Soil erosionand itscontrol3.1 Introduction Soil erosion rate is the gross amount of soilmoved by water and wind. Soil loss is the soil moved off a particularslope or field. Sediment yield is soil loss delivered to apoint under evaluation.Kirkby, M.J. and R.P.C. Morgan. Edited.
