упругоёмкость пласта (the expansion of a given volume of water in response to a decline in pressure. The storativity is defined as the volume of water that an aquifer releases from or takes into storage per unit surface area of the aquifer per unit change in head – dimensionless unit. S = V of water / (unit area)(unit head change) = m3/m2m = m3/m3. The size of the storage coefficient (storativity) depends on whether the aquifer is confined or unconfined. If the aquifer is confined, its water released from storage when the head declines comes from expansion of the water and from compression of the aquifer. In an unconfined aquifer, the expansion of a given volume of water in response to a decline in pressure is very small. evermore) |
