Aim. Creating a parallel programming algorithm for calculating the flow of river basins. Materials and methods. The basis of the theory of unsteady fluid motion laid by Newton, Laplace, Poisson, Navier Stokes, Boussinesq and others. Saint-Venant was the differential equation slowly varying unsteady flow in an open channel not prismatic, called dynamic equation of unsteady flow, or Venant equations. Together with the continuity equation, it is a system of Saint-Venant equations. Results. Constructed a model of streamflow in which each watercourse was divided into n-sites. Each of these sections on their hydrological character-istics unchanged throughout. Imprint area n i calculated data are input for the site n i+1. The task involves the complete transformation of the flood wave on the ground first, then the second and subsequent sections. This is the most efficient in terms of execution speed of the algorithm.
