A graph over time of salinity and conductivity at an upper estuary site will be less inclined than that at a lower estuary site.
Salinity is a measure of the salt content of a water body.
Conductivity is a measure of the electrical conductivity of a solution or substance.
Conductivity increases with increase in salinity.
An estuary is a region where salt water from the sea meet freshwater from a river or stream.
At an upper estuary site where farmers use the water for irrigation, there will be decreased salinity and conductivity with time, while at a lower estuary site where there is a bream and flathead fishing industry, their will be increased salinity and conductivity with time.
Therefore, a graph over time of salinity and conductivity at an upper estuary site will be less inclined than that at a lower estuary site.
