The present study has integrated both spatially and temporally varying drought vulnerability factors to develop an integrated drought vulnerability map for Dhasan basin. A drought vulnerability index is used to classify the study area into different vulnerability zones. From the drought vulnerability assessment for the study area during July 2002, it was observed that the northeast, northwest and extreme southern part of the basin (20% area) was under critical vulnerability condition whereas the southwest and central part of the basin (79.9% area) was under high vulnerability condition. The critical drought vulnerability condition existed in Dhamoni, Pidaruwa, Sagar, Patharia Hat, Chhapri, Baroda Sagar and Singtoni region, whereas high vulnerability condition existed in the remaining parts of the study area. The integrated drought vulnerability approach gives superior result for drought assessment as compared to vulnerability assessment by considering the individual factors for the study area.

Abstract


The present study has integrated both spatially and temporally varying drought vulnerability factors to develop an integrated drought vulnerability map for Dhasan basin. A drought vulnerability index is used to classify the study area into different vulnerability zones. From the drought vulnerability assessment for the study area during July 2002, it was observed that the northeast, northwest and extreme southern part of the basin (20% area) was under critical vulnerability condition whereas the southwest and central part of the basin (79.9% area) was under high vulnerability condition. The critical drought vulnerability condition existed in Dhamoni, Pidaruwa, Sagar, Patharia Hat, Chhapri, Baroda Sagar and Singtoni region, whereas high vulnerability condition existed in the remaining parts of the study area. The integrated drought vulnerability approach gives superior result for drought assessment as compared to vulnerability assessment by considering the individual factors for the study area.
