Reference = actual situation including already decided measures; scenario 1 = flood conveyance (infrastructure works in
the city); scenario 2 = flood storage concentrated in nature areas upstream; scenario 3 = flood storage distributed in the
valley; scenario 4 = further upstream flood storage in Wallonia; scenario 5 = non-structural measures (prevention, flood
forecasting, resilience measures and improved assistance). Note that in this exercise, a combined scenario of structural
and non-structural measures was not included.
