How to Calculate the Specific Yield of an Aquifer? | Groundwater
Article shared by :
While porosity is a measure of the water-bearing capacity of the formation, all this water cannot be drained by gravity or by pumping from wells, as a portion of the water is held in the void spaces by molecular and surface tension forces. The volume of water, expressed as a percentage of the total volume […]
How to Calculate the Storage Coefficient of an Aquifer? | Geography
Article shared by :
Storage coefficient of an aquifer is the volume of water discharged from a unit prism, i.e., a vertical column of aquifer standing on a unit area (1 m2) as water level (piezometric level in confined aquifer—artesian conditions) falls by a unit depth (1 m). For unconfined aquifers (water table conditions) the storage coefficient is the […]
