Abstract
In Canada, flooding is caused by hydrometeorological mechanisms individually or in combination, and, less commonly, by the formation and failure of natural dams. Between 1900 and June 1997, there have been 168 known Canadian flood 'disasters'. These events are clustered in the south in Eastern Canada, whereas they generally are spread throughout Western Canada, but with some clustering in southern Manitoba and southwestern British Columbia. Floods are an important part of the flow regime of alluvial rivers, with geomorphic effects ranging from minor/negligible to large-scale erosion and deposition that completely alters the character of the pre-flood channel and valley bottom. Along many rivers, the impacts of flooding have been reduced by the careful management of flood-prone lands and by the construction of flood-protection infrastructure. Climate change may be altering the frequency of extreme flood events and thus increasing the risk of occupying flood-prone lands along some rivers.
