Description :
The aim of this paper is to present the findings of a field-based study on the rates of gully erosion in the Siwalik Hills. Three large and active gullies were selected. Aerial photographs taken in 1964, 1978 and 1992 were ortho-rectified and use to study the dynamics of gully heads. The same gullies were also monitored manually. The findings are useful for planning and executing appropriate control measures and constructing a sediment hazard map at the catchment scale.
