7.3.3 Analysis of Landslide Hazard Risk

Study represents that the watershed is dominated by high landslide hazard risk
followed by very high, moderate and low landslide hazard risk. In terms of areal
coverage, 17.92, 25.37, 29.35 and 27.34 % area of the watershed is recognized by
low, moderate, high and very high landslide hazard risk respectively (Fig. 7.10 ).
Figure 7.11 shows the spatial distribution of landslide hazard risk where Lower
Paglajhora, Tindharia and Shiviter are registered with high risk exposure due to
