Soil water storage equation
WebMar 30, 2024 · ETc = I + P + U – D – R – ΔS. In above equation, important thing is to find ΔS (change in soil moisture) and for ΔS I have two different values. Firstly, moisture contents … WebThe reference to water storage is important because it ensures that the water budget accounts for all the water within the system. For example, soil moisture counts as a mechanism of water storage. If the equation did not account for this, then it wouldn't accurately represent the amount of water in the system.
