1 IN NORDHAVN A BARRIER OUT TOWARDS THE ORESUND (THE SOUND) CAN BE ESTABLISHED AS A DAM WITH GATES IN KRONLOBET AND LYNETTELOBET THAT ARE CLOSED WHEN THERE IS A RISK OF HIGH WATERS THAT MAY CAUSE DAMAGE TO AREAS CLOSE TO THE HARBOUR.
2 IN SOUTH, PROTECTION CAN BE PROVIDED BY ESTABLISHING BARRIER SOUTH OF KALVEBODERNE IN THE FORM OF A MOVABLE GATE.

FLOODS IN 100 YEAR RAIN EVENT
IF NO FORM OF CLIMATE ADAPTATION IS UNDERTAKEN, THIS WILL BE THE SCENARIO OF CORE URBAN AREA OF COPENHAGEN. MASSIVE FLOODS ON 742 HECTARES OF THE CITY. LARGER GREEN SPACES NOT PART OF THE WATER RETENTION STRATEGY.
FLOODS IN 100 YEAR RAIN EVENT WITH ADAPTATION MEAASURES
THE INTENSITY OF RAIN HAS RISEN BY 40% SINCE 2010. AN AREA OF 235 HECTARES IS FLOODED, COMPARED WITH 217 HECTARES IN 2010. THE SMALL DIFFERENCE IS BY STRATEGIZING RETENTION AND CHANELLING USING BLUE-GREEN SURFACE SYSTEM AND DISCONNECTION OF 30% OF STORMWATER FROM THE SEWER
