Areas Threatened by Shallow or Rising Water Tables
Stream salinity is a useful indicator of catchment salinity. It may be comprised of baseflow (groundwater) and surface water components. Baseflow salinity is important because it indicates the relative contribution of groundwater salinity to total stream salinity.
In more rapidly-responding local groundwater flow systems, rising baseflow salinities over time generally indicate an increasing groundwater contribution to the stream flow and, therefore rising water tables. It is also an (more)...
