10 5 The total rainfall hyetograph of a storm, which took place over a basin is given below. Ordinates of Total Storm Hydrograph (TSH) obtained for the basin is given in the table below. The baseflow is constant and is 3 m/s. If the depth of excess rainfall is 6 cm, determine: a) depth of direct runoff, i (mm/hr) b) depth of infiltrated water, c) -index, d) equation of surface runoff hydrograph in terms of UH3 and lag times. e)...

*JJ 19-3 Try your hand at modeling runoff in a very simple way. Runoff (Q) is the volumetric flow resulting from what is called "excess precipitation" (precipitation minus abstractions). For this problem, the only abstraction is infiltration. Calculate runoff in m/h assuming a 1.0-hectare area (10,000 m2) divided into half permeable and half impermeable (no infiltration) areas. For the permeable area, use the following Horton parameters: fo-2.0 cm/hr, f-0.3 cm/h, k-2.5 h'. Apply a constant 0.4 cm/h rainfall. If the...
