HydraulicStream Node
HydraulicStream is an hydraulic erosion operator using the flow stream approach and an infinite flow direction algorithm for simulating the erosion processes. Simulate water flow across the terrain using the infinite flow direction algorithm. As water flows over the terrain, flow accumulation representing the volume of water that passes through each point on the map, is computed to evaluate the erosive power of the water flow.
