5. RESULT
The result from the neural network model (Table 1) shows that the flooded area in 2001, 2002,
and 2003 covering 703.47 square kilometers, 369.82 square kilometers, and 408.09 square
kilometers respectively. It is found that in 2001 and 2003, the flooded area obtained from the
model are quite greater than the reference data especially the flood in 2001. However, the
overall accuracy of flood extent in 2001, 2002 and 2003 were 86.01 %, 91.68 and 87.74 %
respectively.
