การประเมินศักยภาพการบรรเทาปัญหาอุทกภัยในพื้นที่ลุ่มแม่น้ำมูลบริเวณจังหวัดบุรีรัมย์และสุรินทร์ด้วยแบบจำลอง MIKE11

Abstract

The objective of this study is to apply the MIKE11 model to simulate flood conditions and provide strategies to mitigate flooding in the Mun River in Buriram and Surin provinces. This model  was employed to recreate the unidirectional flow of the Mun river. The research area gathered flood mitigation measures from relevant agencies and identified two specific entities involved: the Marine Department and the Department of Water Resources. This study used 3 measures: flood retention area (SN.01), river dredging (SN.02), and flood retention area combined with river dredging (SN.03). According to the findings, the flood retention area, together with river dredging (SN.03), was the most suitable option when compared to the current state of the river. By applying the flood event of 2017 as a case study, the flow discharge in Buriram and Surin Provinces was projected to increase by 608.19 and 754.79 cubic meters per second, respectively, in comparison to the pre-flood conditions of 2017. Furthermore, it successfully reduced the extent of flooding in community areas from 3,759.36 rai to 2,220.93 rai, equivalent to a drop of 40.92%.
