Application of Analytical Hierarchy Process (AHP) and Frequency Ratio (FR) Model in Assessing Landslide Susceptibility and Risk - Semi-quantitative Approaches for Landslide Assessment and Prediction - page 219

The derived prioritized factor rating values (PFRV) were high for Slope steep-
ness (0.2944), lithology (0.2150), drainage (0.1537), and lineaments (0.1087)
indicating as the signi

cant contributing factors for landsliding in the Shivkhola
watershed. The slope aspect, settlement density and LULC were registered with
minimum prioritized factor rating values of 0.0149, 0.0193 and 0.0266 that proved
these factors as less signi cant to promote landslide activities. Road contributing

area (RCA), slope curvature and upslope contributing area were proved to be
moderately important in the present context. Analytical hierarchy process is proved
to be important

ciently identify the landslide triggering factors of most
importance. It may again be helpful as a support in decision making process for
ef

to ef

cient management. The study revealed that lithological composition with steep
slope and drainage network orientation are to be given more priority in the decision
of structural construction, specially the construction of roads.
