"Report of landslide and sinking at Tawaghat and its surrounding areas have been reported in past also with noticeable amount of loss of lives and properties. A sizeable landslide occurred in this region in December 1962. During August 1977, a major landslide came roaring down the main nala of Khela village and destroyed sheds and houses killing 44 persons and 76 head of cattles. About 150 acres of standing crops were washed out. Geological and geomorphological investigation showed that a large area was dislocated at the head of the nala, moving down the gradient and activating the boulder filled nala. The mass of the mountain scree that moved was perhaps resting already at a critical angle and the torrential rains had triggered the flow. In August 1979 again a major gravitational slide had occurred, seriously affecting Sinsa, Gachhila, and Syankuri village situated on the above slope."

"Under normal conditions, a geomorphic system establishes a steady state with well-adjusted energy and material flow. Rainfall supplies the potential energy to channels and gradient converts it into kinetic energy. Thus, as a result of this process, erosion occurs. Hence, the moment adjustment between energy and material will be disturbed, the system will be distorted and the result will be slope instability. The present paper has been designed to evaluate the mechanism of slope instability with special reference to Central Himalayan district of India."

"In general, hydrological cycle in forested areas is a complicated phenomenon. In Himalaya the vegetative cover plays a vital role in determining several hydrological characters. For the experimental study of oak and pine forests hydrology, two representative basins are selected in the Central Himalaya. After evaluating the hydrological properties of oak and pine forests, it is decuded that both the vegetationt types have different hydrological characteristics. However, with the destruction of vegetation and top soil, rainfall quickly runoff as stormflow instead of soaking into the soils."
