through soil. Infiltration is defined as the downward entry of water into the soil or rock surface (SSSA, 1975) and percolation is the flow of water through soil and porous or fractured rock. In hydrologic. modeling, these two processes are usually modeled separately. Infiltration rate is the rate at which a soil.
surface gets wet. The rest of the water is runoff. 4. How does vegetation slow and prevent sediment loss? Vegetation can slow and prevent sediment loss because it has a lower runoff rate so the sediment is less likely to be transported away. 5. How does vegetation allow greater infiltration? Vegetation allows greater infiltration because it is able to absorb more water and bring more water deep into the ground beyond the surface. 6. How does pavement or smooth rock runoff affect waterways?
