Hazard Analysis Method

is a factor of climate change characterized by changes in rainfall patterns. To analyze the availability of water, then the model developed in Geographical Information System (GIS). The required data are slope, rock data and rain water absorption as the trigger of decreasing of water availability. Then the data is analyzed using GIS and calculated by approach quantitatively to obtain hazard map.

Vulnerability Analysis Method

Vulnerability is defined as a function of the nature, magnitude and rate of climate change as the degree of variation of the affected system. Its sensitivity and adaptability are determined through criteria of significant levels of indicator and hazard relationships. The water availability vulnerability indicator can be seen in Table 3.
