All the rivers ultimately drain into seas. However, river water is not saline while sea water is saline. Why?

Rivers while draining into tht: seas deposit the sus-pended matter at the mouth forming delta. They carry the dissolved salts into the seas. As a result, the water becomes concentrated with dissolved salts. This imparts salinity to sea water.
