The movement of water in soil capillaries
WebSep 29, 2024 · The capillary forces are in action in the soil water also because the size of the pores is very small. When we put a drop of water on soil and observe the movement closely, we can find the water moving in the horizontal direction as well as in vertical direction (downwards). WebThe movement of water into the soil or ground surface is called: a) percola/on. In which one of the following basins would a stream respond slowly to a precipita7on event? c) a small basin in size. During dry periods, most of the discharge in stream channels of the humid temperate zone is from: c) surface runoQ (overland >ow) Weathering: c ...
