The National Rivers Authority Thames Region has commissioned WRc to undertake two time of travel studies on a section of the river Wandle, one during high flow conditions and the other during medium flow conditions. The section of river investigated was from Beddington sewage treatment works to the confluence with the river Thames. Having completed the medium flow study, it became apparent that there was a large daily variation of flow in the lower Wandle caused by the dominance of the Beddington discharge. Therefore, it was decided that the second tracer study should be undertaken when the flows in the upstream Wandle were similar to those found during the first study but with the flow from the Beddington works significantly higher. This would allow the effects of the Beddington discharge on the travel time in the Wandle to be studied. During each of the tracer studies the dye tracer was added to the Beddington effluent channel and the resulting tracer cloud was monitored in situ as it passed through four preselected detection sites.
