Abstract
Numerical modelling of flood inundation often requires fast and accurate results. This research presents subgrid based model that computes discharge in a coarse grid but uses fine-grid to consider high resolution bathymetry data & roughness variations. Using this model, 2014 flood observed in Pakistan is modelled in different reaches of Chenab & Jhelum River and it is compared with observed discharge values. It is shown that this model gives fast & accurate results and coarse grid simulation results become as good as high resolution data results but at much lower cost. Upwind & Constrained Interpolation Profile (CIP) schemes have also been used in this research and results of these schemes are compared with double grid method.
