Integrated 1D/2D Urban Inundation Modelling with Refined Grid and OpenMP Parallelization
Abstract Urban area consists of artificial structures such as buildings, roads, walls, parking lots etc. Therefore, the generation of fine meshes is a crucial component in depicting the complex urban features. However it accompanies huge amount of computational load with impractical calculation time. In this study, computational load reduction methods are tested using integrated 1D/2D urban inundation model based on refined grid with OpenMP parallelization technique. Refined grid (10 m with 5 m resolution) was able to reduce surface grid 2.47 times compared with regular grid (10 m resolution) and OpenMP parallelization shows 3.67 times running time reduction compared with serial code.
