cient value ranges between 0.19 and 7.24 and here the values of 0.75, 1.45, 2.55,
3.85, 4.90, and 6.15 were taken into account as threshold points to classify the
watershed into 7 landslide risk intensity zones. Risk exposure map (Fig. 7.7 ) shows
the intensity of risk elements over the space which were delineated here as very low
to very high ranges. The intensity of risk elements are high to very high at Tindharia
Upper as well as Lower, very few parts at Gayabari upper slope, Giddapahar,
Shiviter, and upper Paglajhora.
