Abstract

If an unpolluted tributary joins a river less than about thirty channel breadths downstream of an effluent outlet, then the additional dilution can reduce the peak pollution level experienced at the shoreline. This paper identifies the optimal sites for steady discharges to take full advantage of the extra dilution.
