Analysis of significance of environmental factors in landslide susceptibility modeling: Case study Jemma drainage network, Ethiopia
Abstrakt
Aim of the paper is to describe methodology for calculating significance of environmental factors in landslide susceptibility modeling and present result of selected one. As a study area part of a Jemma basin in Ethiopian Highland is used.
This locality is highly affected by mass movement processes. In the first part all major factors and their influence are described briefly.
Majority of the work focuses on research of other methodologies used in susceptibility models and design of own methodology. This method is unlike most of the methods used completely objective, therefore it is not possible to intervene in the results.
In article all inputs and outputs of the method are described as well as all stages of calculations. Results are illustrated on specific examples.
In study area most important factor for landslide susceptibility is slope, on the other hand least important is land cover. At the end of article landslide susceptibility map is created.
Part of the article is discussion of results and possible improvements of the methodology. (C) 2017 The Authors. This is an open-access article distributed under the terms of the Creative Commons Attribution License.
