2. Situation of dikes in relation to hydraulic hazards
Before looking at dykes, and more specifically the structures that make them up, it is necessary to first identify the hazards against which we wish to protect ourselves.
2.1 River flooding and marine submersion hazards
Flooding is the result of a meteorological phenomenon (rain or storm) and is characterized by a rise in surface water level or in the water table. These hydraulic phenomena are generally accompanied by morphological changes (suspension, transport, sediment deposition, etc.). Depending on the site under consideration, flood scenarios can vary considerably. Each flood is therefore a special case, in terms of its causes, course and consequences. The expression of the hazard generated by a flood is not uniform and constant, but varies over the...
