Surface Water Flow simulation using cellular automata based flow direction D-infinity algorithm

Simulation of surface water flow or runoff is one of the most important thing in order to understand a natural phenomenon when a public policy is under consideration. Generally, runoff simulation is only limited to one flow result thus it is difficult to make a decision. This limitation can be resolved by doing some iterations to get more accurate results. Repeated iterations can be conducted using cellular automata method combined with the flow direction D-infinity algorithm as the transitions. The simulation results in this paper gives a continuous simulation appropriately according to the number of desired iterations. Based on the simulation results, the surface water flow can be determined and therefore the utilization of the quantity of rainwater for various purposes can be used in any areas.
