Numerical Analysis of Steady Gradually Varied Flow in Open Channel Networks with Hydraulic Structures
In this paper, a method for numerical analysis of steady gradually varied fl ow in channel networks with hydraulic structures is considered. For this purpose, a boundary problem for the system of ordinary differential equations consisting of energy equation and mass conservation equations is formulated. The boundary problem is solved using fi nite difference technique which leads to the system of non-linear algebraic equations. The arising system is solved with modi fi ed Picard method. The presented methodology is applicable to any channel network type and any type of hydraulic structure.
