%X The data set is the flow data set of the whole basin in the upper, middle and lower reaches of the Yellow River. The traffic threshold is 15000The main purpose of confluence analysis is to determine the flow path. The number of inflow points in each grid cell on the upstream grid represents the flow direction of the grid. The area with larger nip can be regarded as river valley, while the area with nip equal to 0 is higher, which may be the watershed of watershed. The basic idea of confluence analysis is that there is a unit of water at each point of DEM represented by regular grid. According to the law of natural water flowing from high to low, the water flow value of each point is calculated according to the flow direction grid of the area, and then the regional concentration grid (cumulative amount of confluence) is obtained.
