of distance. Result of the IDW analysis of rainfall distribution is further used as a
thematic layer in the calculation (Fig. 13).
3.3 Hierarchical Fuzzy Logic
Fuzzy logic is a tool to deal with uncertainty where normal probability theory fails
to work due to large computational expensiveness. Fuzzy logic takes into account
all the possible combinations of inputs and possible outcomes for each case. It then
considers the possible fuzziness of the output and gives a more humanlike response
