Abstract: Abstract The purpose of this paper is a computational algorithm for simulation and visualization of flood inundation on natural topography. The algorithm is constructed based on the shallow water equations, which are solved numerically using an adaptive tree grid finite volume method that is also equipped with the dynamic domain defining technique. The algorithm is tested to simulate the flood inundation in Thailand. The results are compared with the non-adaptive finest grid simulation. The comparison shows that the algorithm can reduce the number of grid cells and the computational times, without much loss of accuracy in the results.
