Les offices de conservation de la nature et le ministère des Richesses naturelles peuvent aider en fournissant une cartographie des plaines inondables et des données historiques, qui permettront de mieux identifier les zones vulnérables et les conséquences possibles (comme les menaces pour la population, les biens, l’industrie, les infrastructures essentielles, etc.).
How extensive flooding will be in any area of Ontario is determined generally by topography, the amount of water storage capacity, the river channel route (meandering streams), the types of land uses and the amount of inflow to the watershed. High water levels are often the result of extreme watercourse flows, which are produced by extreme rainfall and snowmelt. In many areas floods will occur because of a reduction in the natural channel capacity due to ice and debris jams. Ice and debris “block” the ability of water to move and as a result the water floods the land outside the watercourse. Flooding also occurs on the Great Lakes and large inland lakes, and is often the result of high lake water levels combined with wind and rain.
