Abstract | Water induced disasters are common phenomenon in the mountainous region of the active Himalayan belt. It is the major cause of annual loss of lives and properties in Nepal. The water induced disaster management is generally carried out in basin, sub-basin or watershed level through watershed management approach. Exploration of water induced disaster and evaluation of appropriate watershed management in Dobhan watershed in Palpa district, west Nepal has been carried out. Water induced disaster events like landslide, bank cutting, flood and sediment transportation are common in the watershed. Around 20% of the Dobhan watershed is covered by agriculture land and majority of it is on the sloping terrace. Though more than 65% watershed area is covered by forest, there is significant encroachment leading to degradation of the forest area and natural condition of the forest. Watershed related information, like geology, geomorphology, river morphology, land use, socio-economic conditions of the people in the watershed are some of the factors to be considered in the watershed management leading towards water induced disaster risk reduction. This paper presents various parameters and approach required for watershed management of the Dobhan Khola watershed, which is equally important to deal with other watershed of the country in holistic manner for the mitigation of water induced disasters. |
