Route an overland flow hydrograph over a distance of 500 m using the analytical kinematic wave solution with variable wave celerity. The overland flow occurs over a 75 m wide plane strip of constant slope 0.006 and n = 0.014. The inflow hydrograph is triangular with a peak of 1.25 m³/s at a time to peak of 15 min and with a time base of 45 min. The initial base flow is 0.25 m³/s. Plot the inflow and outflow hydrographs.
