3) a) Using the SCS (soil conservation services) triangular unit hydrograph method develop the 60 minute UH for a watershed area of 15km2 and a time of concentration of 50 minutes. Sketch or plot the resulting synthetic unit hydrograph showing all significant features. (12 marks) b) Estimate the total runoff for the conditions above. (3 marks) c) C The data presented in table 3.0 represents a precipitation hyetograph for this catchment. Assuming an average storm loss of 11mmhr generate the full hydrograph for the successive events indicated. Sketch or plot the resulting cumulative hydrograph.
