Flood effects on the transport of heavy metals

This paper is concerned with the effect of river flooding on sediment quality in the case of the river Ystwyth in Wales. It is shown that sediment‐associated concentrations of lead, copper and cadmium vary with the river's discharge, and the form in which they are bound to the sediment varies. The ease with which metals can be removed from sediment influences the bioavailability of the metals.
