Abstract: The present invention relates to a method for analyzing a 2D shallow water flow through the assignment of a wetting/drying condition using a critical drying depth method. The purpose of the present invention is to provide the method for analyzing the 2D shallow water flow through the assignment of the wetting/drying condition using the critical drying depth method, capable of obtaining a result with high stability by solving a divergence problem in a dry area generated in an existing model without generating a new lattice according to a boundary condition and a specific simulation method in a shallow water equation model configuration. The present invention controls a problem of a discontinuous boundary surface and prevents an abnormal water depth simulation result and a high flow in the dry area. Thereby, the present invention efficiently and stably analyzes the shallow water flow.
