Fig. 6 shows some of data layers used in the analysis. Each
is depicted in a stretch color scale, where black represents the
highest values and white the lowest values. ArcMap 10.1 was
used to execute the above steps for both SRTM and SPOT
images to extract drainage flow net in the study area. The flow
networks and basin boundaries were then vectored. The basin
characteristics and the morphometric parameters were calculated
from spot DEM.
