Delft3D model of the Ayeyarwady delta Myanmar

Abstract

In 2013 and 2014, a hydrodynamic model for the Ayeyarwady delta was developed. This delta is located in the Southwestern part of Myanmar. Because it is prone to flooding and is also affected by salt intrusion during periods of low river discharge, it was chosen to develop a hydrodynamic model to gain more insight into the aforementioned phenomena. Understanding these phenomena is important since floods affect the safety of the people and salt intrusion impacts the quality of irrigation and drinking water. The main objective of this project is to develop a Delft3D model that can serve as a starting point for modelling these processes. This report will present the development of a 2D tidal model and validation of this model with locally measured data. Also, some preliminary results will be presented for 3D salt intrusion computations. Report I focuses on the setup and calibration of the hydrodynamic model and Report II mainly discusses the validation of the hydrodynamic model with available data.
