Research and application of the parallel computing method for the grid-based Xin'anjiang model
Hydrology Research, 2023 The grid-based Xin'anjiang model (GXM) has been widely applied to flood forecasting. However, when the model warm-up period is long and the amount of input data is large, the computational efficiency of the GXM is obviously low. Therefore, a GXM parallel
