              How do forests help in controlling flood & maintain steady supply of water?

    Answer:

    The uppermost layer of the forest canopy intercepts the flow of rain drops and most of the water comes down through the branches and stems of the trees. From leaves it drips slowly over branches of the shrubs and herbs. All this slows down the speed of raindrops and also slows down the speed of running water. Thus, forests act as a natural absorber of rainwater and allow it to seep. It helps to maintain the water table throughout the year. In this way, forests help in controlling floods and maintaining steady supply of water.
