Hand in Question For the given rain fall data of Eastern Creek shown in the Table below, Cumulative Rainfall for rainfall in particular period Rainfall Intensity Time Time in hr mm (mm ) (mm /hr ) 4:00 4:30 0.5 1.4 5:00 1.9 5:30 1.5 3 6:00 2 5.1 6:30 2.5 8.2 7:00 3 10.9 7:30 3.5 14.3 8:00 22.6 8:30 4.5 29.1 9:00 38 . 1 9:30 5.5 47.. 10:00 47.9 a Calculate the rainfall hyetograph (mm/hr) for the above storm. b (4') Calculate the initial loss when the runoff started to rise at 5:00am. C (3') If the measured total runoff depth is 37.7mm, determine the continuous loss in mm/hr.(3') Solution To determine the rainfall hyetograph (mm/hr), the rainfall in each period needs to be calculated and shown in column four. The rainfall intensity for the particular period of an hour is calculated as follows. Rainfall for half an hour period = 1.4 mm
