GIS Based Landslide Hazard Mapping Prediction in Ulu Klang, Malaysia

Abstract

Since 1993, a number of landslides have been reported in Ulu Klang, Malaysia. These landslides caused fatalities and economic losses. Most of these landslides occurred in man-made slopes. Geographical Information System (GIS) is proposed to be used as the based machine for the production of landslide hazard map. This study highlights the area based landslide hazard assessment at Ulu Klang area using GIS application in order to help the engineer or the town planner to identify the most suitable development area besides predicting the potential landslide hazard area. Four main factors that influence of landslide occurrence were chosen include slope gradient aspect, geology, surface cover/land used and precipitation distribution. Landslide hazardous areas were analyzed and mapped using GIS application and produced a hazard map with five different indexes (i.e., very low, low, medium, high and very high hazard). The results of the analysis were verified using the landslide location data. The result showed that the model was very suitable in predicting landslide hazard and generating landslide hazard maps.

Geographical Information System (GIS)-Based Landslide Susceptibility Mapping in Malaysia: A Review of Past, Current and Future Trends

“…Frequency ratio was used by Saro Lee et al ( 2007), Pradhan, Mansor, et al (2011), Yusof & Pradhan (2014), Huqqani et al (2019) in their research. The weighted overlay was also used 4 times as much as the frequency ratio, by Mukhlisin et al (2010), Mahmud et al (2013), Bong et al (2018), and (Udin et al, 2021). ANNs were also used four times by , Pradhan, Youssef, et al (2010), and Selamat et al (2022).…”

“…The frequency ratio was used 1 times (10%), by Saro Lee et al (2007). The weight of evidence was used 1 time (10%), by Pradhan, Oh, et al (2010), and the weighted overlay method was also used one time, by Mukhlisin et al (2010). Table 5 shows the models used in articles for the second period from 2011 to 2016.…”

“…A landslide is the movement of rocks, debris, and/or soils down a slope, including falls, topples, slides, flows, and spreads [1,2]. They most often occur naturally but can also be trigged by human activities, such as unstable human-made slopes [3], uneven degrees of weathering [4], weak rock units, overadequate precipitation [5][6][7][8][9], and earthquakes [10][11][12].…”
