2 Dimensional (2D) flow modeling is widely used for flood plain analysis and is considered to be a viable tool for evaluating flood propagation. The accuracy of open channel hydraulics and flood plain model is dependent on the refinement of model mesh or grid to represent ground model topography using high-resolution Light Detection and Ranging (LiDAR). This paper examines the sensitivity of unstructured mesh size of two dimensional (2D) shallow water models. The accuracy of simulated overland flood propagation was carried out using the Delaunay refinement method. The study was performed by connecting to the 2D hydrodynamic modeling platform InfoWorks Integrated Catchment Modelling (ICM) using two different methodologies.
