| Summary: | This research was initiated to study the groundwater potential zones using the Fuzzy logic technique at Lembangan Kadamaian, Kota Belud, Sabah, and its surroundings. The lithological units of this study mainly focus on the sedimentary rock of Wariu Formation, Crocker Formation, and Trusmadi Formation, including the quaternary alluvium deposition unit of Kota Belud. Based on the structural geology analysis results, the deformation trends are in the northwest-southeast direction. The interpretation of groundwater potential zones was made by using the ArcGIS Pro, R-studio Global Mapper, and several other mappingrelated software. Ten thematic maps that have been produced are lithological map, lineament density map, rainfall map, distant from river map, distant from lineament map, drainage density map, landform, and land cover map, Topographic Wetness Index (TWI) map, rock porosity map, curvature map, and slope steepness map. GIS techniques were used during the spatial analysis stage. All thematic maps have their class values and are based on field data, relevant department data, and remote sensing data. Further processes were done using R-studio, Fuzzy Toolset, and Raster Calculator. This process afterward will produce the groundwater potential map of the study area. The final result has been supported by the data of tube wells from the Department of Minerals and Geosciences, Sabah, and was validated using the ROC and AUC curve validation technique. |
