Application of Aerial Photo Technique in Mapping and Analysis of Gully Erosion in the Forest-Types of Upper Damodar Valley

Abstract

The Upper Damodar Valley comprising an area of about million acres (about 7,000 sq. miles) presents a geographical area Its forests, of various erosion problems. spreading over an area of one million acres constitute one major land use. But apart from the different types of erosion met with in the denuded parts of it, the densely wooded portions of the forests are also observed to be characterised by severe gullying mainly due to destruction of the humus layer by human and animal interierence of fires, grazing and exposure of the bare soil. Gorrie (1953) has also confirmed the erosion in forest as a serious problem in his report submitted to the Government.
