Abstract

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