Simulation of dynamic Earth surface environment

Now, we can simulate dynamic evolution of Earth surface environment using our own landscape evolution model. Our laboratory has introduced a new global search algorithm for flow path extraction known as Global D8 (GD8) and an improved GD8 (iGD8). Also, we developed the first whole landscape evolution model that uses GD8 (Landscape Evolution model using Global Search, LEGS). Recent version of LEGS, published in 2021, can handle co-evolution of local climate and topography.
