What should be the depth scale?2.12 The data from an isohyetal map of a 24-hour storm is given below. Assuming that the storm centre had an area of 25 km², obtain the Depth-Area curve of this store. Using the depth-area curve, estimate the average depth of rainfall over an area of 2400 sq. km. It can be assumed that the storm centre is located at the centre of the area.
