Abstract
A hydrodynamic model for simulating the flow in Basin irrigation system is presented. An explicit McCormack method is used for solving the governing equations. This method doesn't require any special treatment of advancing or receding fronts such as sub-grid technique. The numerical procedure accommodates for three inflow boundary conditions namely line inflow, corner inflow and fan inflow. The results are compared with observed advance and recession times for two level basin irrigation events available in the literature and two field experiments conducted by authors at WALMI, Vadod, Anand, Gujarat, India. A very good comparison of results is observed. The results for various other cases are also presented.
