Flows downward through the soil profile
WebThis article throws light upon the three main types of movement of water in soil. The types are: 1. Saturated Flow 2. Unsaturated Flow 3. Water Vapour Movement. Type # 1. Saturated Flow: Water moves because of water potential gradients in the soil caused mostly by gravity, salt content and water usage and the direction of flow is from a zone of ...
