The design of existing dikes can be modified to fullfil different purposes. Re-enforcing dikes and dams can increase their stability and resistance against dike breaching, e.g. by strengthening the inner core of the dike, or improving characteristics of the dike's surface that contribute to the overall stability of the dike. Dikes can also be re-enforced by heightening, broadening or by adding spatial components. Embankments also need to be adjusted or the heightened.
