In this paper, we consider three one-dimensional models for investigating the passage of a flood wave in channels with floodplains. When calculating the unsteady movement of water in natural rivers of the plain type, having complicated beds and large floodplains, there are often difficulties associated with the need to take into account the influence of floodplains on the process of passing waves of outflows and floods along the length of the watercourse. Based on the results of overland flow calculations for the climatic model of river flow for one-dimensional models of the passage of the flood wave, calculations were made. The results of calculations of real different probability floods at the fragment Irtysh watershed from Tobolsk to Khanti-Mansisk are presents.
