Infiltration cannot occur if soil is saturated. Infiltration 9 of 14 Vertical movement of water from above the water table. If bedrock is impermeable,no percolation can occur. Perlocation 10 of 14 The water moves laterally at a slow rate. It is transferred to the river through the bed and banks long after a rainfall event. Groundwater flow 11 of 14 Water stored below the water table in saturated soil or rock Groundwater 12 of 14 Occurs during heavy rainfal when the ground is saturated or it's impermeable. Rare except in Urban areas.Also know as Surface Runoff. Overlandflow 13 of 14 Water reaches the ground by flowing down trunks or stems or by dropping ogg leaves. Stemflow 14 of 14
