WebInfiltration is the process by which water on the ground surface enters the soil.It is commonly used in both hydrology and soil sciences.The infiltration capacity is defined as the maximum rate of infiltration. It is most often measured in meters per day but can also be measured in other units of distance over time if necessary. The infiltration capacity … WebChanges in soil moisture storage can be generalized with a mass balance equation (eq. 1) as a result of the difference between the amount of water added and that which is lost (Hillel 1982).
WebThe average salinity of the soil water during a calculation period is: (20) Substituting Equation 20 for EC SW in Equation 17 yields the salt storage equation: (21) Equation 21 can be used to calculate changes in soil salinity within a cropping season. The salt storage equation can also be applied to the four-layer concept. WebIn the field of hydrogeology, storage properties are physical properties that characterize the capacity of an aquifer to release groundwater.These properties are storativity (S), specific storage (S s) and specific yield (S y).According to Groundwater, by Freeze and Cherry (1979), specific storage, [m −1], of a saturated aquifer is defined as the volume of water that a …
