چکیده
Due to Tropical Storm Dianmu’s influence in the Lam Khan Chu watershed (LKCW) area, central Thailand saw its worst flood 50 years from September 23 28, 2021. The flooding lasted for 1-2 months. objective of this research is study susceptibility using logistic regression analysis LCKW area. According 11 floods occurred repeatedly between 2005 and 2021, southern Bamnetnarong district continued northeast Chaturat Bueng Lahan swamp. These areas are main waterways LKCW stream Huai Khlong Phai Ngam, which dominant flow patterns braided streams. factors influencing geology, frequency, topographic wetness index, drainage density, soil, power land-use, elevation, mean annual precipitation, aspect, distance road, village, stream. results shed light on these factors. All such variables were demonstrated by β value coefficient. area’s was projected a map, it discovered have extremely high levels susceptibility, encompassing regions up 148.308 km 2 (8.566%) 247.421 (14.291%), respectively, vicinity two river sides watershed. As result map will be used as guideline future planning monitoring.
