As my doctoral research, I investigated the sediment dynamics in a large shallow lake and its floodplain characterized by flood pulse. The targeted shallow lake was Tonle Sap Lake (TSL), the largest freshwater lake in Southeast Asia, located in Cambodia. An extensive and seasonal sampling survey was conducted to measure total suspended solid (TSS) concentrations, sedimentation and resuspension rates in TSL and its four floodplain areas. The study revealed that sedimentation process was dominant in the high water period (September–December) while resuspension process was dominant only in the low water period (March–June).

I also successfully applied a landscape evolution model (Caesar-Lisflood) in TSL, having a good and acceptable simulation performance for the water level and TSS concentration, respectively.

Currently, my research aims to investigate the distribution and health risks of harmful pathogen at a floating village in TSL through the application of 3D hydraulic model, named Tokyo Institute Technology - WAter Reservoir Model (TITech-WARM). This research is a part of a SATREPS project in Cambodia entitled of "Establishment of Environmental Conservation Platform of Tonle Sap Lake".
