In which type of soil surface will rain water runoff be maximum after heavy rains? 1)Sandy surface 2) Grassy surface 3) Impermeable surface 4) Nearly flat surface
Alluvial soils have an organic matter content that decreases irregularly with depth and they receive fresh sedimentary materials at regular intervals if flooded. Because they are located in poorly drained valleys, alluvial soils are prone to waterlogging.
When it rains, water falling to the surface of the soil will either infiltrate into the soil or run off along the surface. Part of the water that infiltrates into the soil will be absorbed by the upper soil layers and part will seep down into the deeper soil layers. The part of the water that does not or cannot infiltrate will run off along the surface of the soil.
