Key Info
  • Cities on flood plains
  • Duration: 04:24
  • The Rideau River is one of Ottawa's main waterways. It winds its way through the city and in the winter the river is frozen solid. Spanning across the Rideau river is a low footbridge which has caused a solid wall of ice to form over the waterfall. The ice has created a natural dam, causing the river's water level to rise, which in turn threatens to flood nearby homes and businesses. Demolishing this natural dam takes a man-made solution – dynamite! Created especially for Class Clips from the BBC series Human Planet, first broadcast in January 2011.

Ideas for use in class
  • Compare climate graphs for Ottawa and London. Students could identify the impacts of floods in urban areas. Initiate discussion on response to such hazards from MEDC's, compared with LEDC's. More information about the series, images and further clips can be seen on the Human Planet website:
