definitionThe “system of cascading flood compartments” combines area prevention with constructional solutions. The idea is to (re)build a second dikeline of polders behind the primary dike, thereby creating a system of different compartments. Polders are low lying areas enclosed by embankments or dikes. In the case of a dike overflowing, the system diverts the water to the hinterland
(Knieling J. and Schärffer M., 2011, p. 8).
Co-benefits and impactsA failure response strategy to contain the flood migration in case of levee overtopping with the objective to gain time for emergency response and to reduce the consequences of flooding of the hinterland (Pasche E. et. al., 2008).
