Abstract
Erosion and sedimentation are natural processes. However, man's activities, especially agriculture, have greatly increased soil erosion and the input of sediments to streams in southern Ontario. Currently, environmental researchers are paying more attention to sediments because of their importance in the transport of nutrients and toxic chemicals. There is also increased public awareness of soil erosion and sedimentation problems in Ontario. Although the present discussion deals only with the impact of sediments on streams, it is often impossible to distinguish between the effects caused by sedimentation, altered flow regimes and higher water temperatures. These parameters are interlinked and are the result of deforestation of stream banks for agriculture and urbanization. The approach taken here is to first briefly discuss the physical/chemical aspects of sediment transport in streams, followed by retention devices, and then the biological impact sediments on stream communities.
