From these results we can conclude that, low resolution
DEM (SRTM) gives low surface slope and higher time of concentration
for extracted basins. This explains why high
resolution model (SPOT) gives more area that has very high
index value (9% of total area under very high risk by using
SPOT model while 3% by using SRTM). 4 districts (75, 31,
39, and 1) have the same index value from two models.
