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.
