A subsurface drainage network mainly carries unsteady flow and data are not usually available for model parameters calibration in such networks. In the present research, the finite volume method using the time splitting scheme was employed to develop a computer code for solving the one dimensional unsteady flow equations. Using corrugated sub-drainage pipes, an experimental prototype setup was constructed to examine the numerical model response in predicting the observed unsteady data in suchfatcat:dev6mjezlnbtzdosxp5os3h7wu
