Mathematical Models of the Optimal Distribution of Water in the Channels of Irrigation Systems

N the article the problem of optimal water distribution in the canals of irrigation systems is solved in the case of using as a mathematical model of un steady water movement in the canal sections the system of full differential equations of Saint-Venant, and alsonumerical decisions on a method of a finite difference of systems of differential equations of Saint-Venant for system of automatic regulation of a water level in a channel site are resulted.
