Abstract

Flooding has always been one of the major hazards in Myanmar, accounting for 11% of all disasters. The Bago River Basin is a floodprone area in Myanmar, where, during the last decade, many severe floods occurred during the monsoon season, usually in July and August. Most of these floods are caused by storm rainfall. The 2011 and 2018 floods form part of the historical record of Bago. The main objective of this research paper is to develop a new hydrological model (WEB-DHM) for the Bago River Basin using observed station data to represent floods in the study area. The Water and Energy Budget-based Distributed Hydrological Model (WEB-DHM) was used for hydrological modeling as determined for the discharge of floods. The HydroSHEDS digital elevation model is used for the discharge estimation and analysis of the WEB-DHM. The Japanese 55-year Reanalysis JRA-55 data, from the Japan Meteorological Agency (JMA), were used for the preparation of meteorological data for this model. The results of flood discharge from the hydrological modeling and the observed data of the past three years (2014, 2015 and 2016) are provided in this study.
