Estimation of Monetary Values of the Ecosystem Services Flow at the Tidal Elbe River

Table 1

Flood mitigation strategies involved for determination of better flood risk mitigation strategy.

Strategy (scenarios)	Kilometers along the river	Area in hectares (ha)	Storage capacity in mio (m^3)	Flood risk mitigation strategy
DS + 1 (dike heightening)				Implementation of the design standard of a 100-year recurrence interval with an additional freeboard of 1 m for all dikes in Sachsen
DR I (dike shifting)	117–536	34658	738	dike relocation (uncontrolled operation) of 60 potential sites
DR II (dike shifting)	120.5–536	9432	251	Dike relocation (uncontrolled operation) of the 33 potential sites identified in the IKSE action plan
POL A (controlled retention)	117–427	25 576	494	Controlled operation of 31 potential sites for retention polders identified in the IKSE action plan
POL P (controlled retention)	180	4557	138	Controlled operation of only the largest 5 potential sites for retention identified in the IKSE action plan
POL H (controlled retention)	427	9909	112	Controlled operation of the 8 existing retention polders, at the mouth of the River Havel near Elbe
