For to claim that a proposition is necessary is to claim that it is true in all contexts, whilst to maintain that it is a posteriori or informative is to...
متن کاملThe Pattern of Caspian Sea Water Penetration Into Anzali Wetland: Introduction of a Salt Wedge
Measuring salinity of water at different depths along six transacts at the mouth of the wetland and along five tributaries connecting the wetland to the sea the extent of Caspian Sea penetration into Anzali Wetland was determined. The results demonstrated a depth-dependent salinity gradient extending up to 10 kilometres into the wetland. A pattern of saltwater and freshwater interface is presen...
