description | Identification of high potential risk and susceptible zones for natural
hazards of geological origin is one of the most important applications of
advanced remote sensing technology. Yearly, several landslides occur during
heavy monsoon rainfall in Kelantan River basin, Peninsular Malaysia.
Flooding and subsequent landslide occurrences generated significant damage to
livestock, agricultural produce, homes and businesses in the Kelantan River
basin. In this study, remote sensing data from the recently launched Landsat-8 and Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2) on board the Advanced Land Observing Satellite-2 (ALOS-2) were used to map
geologic structural and topographical features in the Kelantan River basin
for identification of high potential risk and susceptible zones for
landslides and flooding areas. The data were processed for a comprehensive
analysis of major geological structures and detailed characterizations of
lineaments, drainage patterns and lithology at both regional and district
scales. The analytical hierarchy process (AHP) approach was used for landslide
susceptibility mapping. Several factors such as slope, aspect, soil,
lithology, normalized difference vegetation index (NDVI), land cover,
distance to drainage, precipitation, distance to fault and distance to the
road were extracted from remote sensing satellite data and fieldwork to
apply the AHP approach. Directional convolution filters were applied to ALOS-2
data for identifying linear features in particular directions and edge
enhancement in the spatial domain. Results indicate that lineament
occurrence at regional scale was mainly linked to the N–S trending of the
Bentong–Raub Suture Zone (BRSZ) in the west and Lebir Fault Zone in the east of the Kelantan state. The combination of different polarization channels
produced image maps that contain important information related to water bodies,
wetlands and lithological units. The N–S, NE–SW and NNE–SSW lineament trends and dendritic, sub-dendritic and rectangular drainage patterns were detected in the Kelantan River basin. The analysis of field investigation data indicates that many of flooded areas were associated with high potential
risk zones for hydrogeological hazards such as wetlands, urban areas,
floodplain scroll, meander bend, dendritic and sub-dendritic drainage
patterns, which are located in flat topographic regions. Numerous landslide
points were located in a rectangular drainage system that is associated with a
topographic slope of metamorphic and quaternary rock units. Consequently,
structural and topographical geology maps were produced for Kelantan River
basin using PALSAR-2 data, which could be broadly applicable for landslide
hazard mapping and identification of high potential risk zone for
hydrogeological hazards. Geohazard mitigation programs could be conducted
in the landslide recurrence regions and flooded areas to reduce natural
catastrophes leading to loss of life and financial investments in the
Kelantan River basin. In this investigation, Landsat-8 and ALOS-2 have
proven to successfully provide advanced Earth observation satellite data for
disaster monitoring in tropical environments. |
