Abstract
This paper describes a method for analysis of various input parameters used in preparation of Landslide Hazard Zonation Maps. The method is based on the quantitative approach, which includes four Landslide Hazard Evaluation Factors grouped into four ranges of values. Since the various parameters are not equally important for estimation of Total Landslide Hazard Evaluation Factor (TLHEF), importance ratings are allocated to the different value ranges. Importance ratings for Lithological types (LT), Ground Water Level (GWL), Slope Angles (SA) and Soil Debris Cover (SDC) are defined using polynomial interpolation. With this procedure, each evaluation factor is related to the corresponding ratings using interpolation charts and equations. Based on the correlation between the adequate parameters and the rating, the Total Rating Hazard Evaluation Factor can be calculated.
