Over exploitation of available natural resources for meeting the increasing demand of ever growing population for food, fuel and fibre has led to serious environmental degradation. Globally, an estimated 1,965 million hectare of land are subject to some kind of degradation. Of this, 1,094 million ha land are subject to soil erosion by water and 549 million hectares of land to soil erosion by wind. In India alone, out of 329 million hectares geographical area, an estimated 150 million hectares of land are subject to soil erosion by water and wind erosion. Furthermore, an estimated 3,975 million hectares of land are highly dissected and have an intricate network of gullies.

In a broad geologic sense, erosion means wearing away of the earth's surface by the forces of water and wind. Soil erosion could be either natural or accelerated. Natural erosion in the natural landscape may be either a gradual process, with a soil cover on the land continuously or a catastrophic one. Natural erosion is important in soil development. Accelerated soil erosion truncates the soil profiles formed in the natural landscape. In applied soil science and agriculture, erosion is used in a restricted sense. The terms "erosion" and "soil erosion" are often used for accelerated soil erosion, or that erosion of soil resulting from disturbances of the natural landscape, usually by man in contrast to the natural or normal erosion that takes place in the disturbed landscape.

In the present paper efforts have been made to identify the gully erosion areas along the Chambal River using Remote Sensing Techniques. The study also shows the extend, pattern, status of gully erosion, and their depth where reclamation measures can be taken to arrest the soil erosion.
