Water quantities and budget. For Hydrology Compute the change in water storage of the surfacewater system of certain area with precipitation of 30mm,evaporation of 1am and transpiration is half of the rate ofevaporation. Neglect groundwater flow in the stream andthe surface water flow into the system is equivalent to theflow outgoing from the system. Assume that the soil in thearea is saturated all throughout. Using 2D-diagraminterprets the situation, include all factors affecting thesurface water system.
