© ClimateTechWiki and respective owners Flood-proofing

The primary objective of flood-proofing is to reduce or avoid the impacts of coastal flooding upon structures.  This may include elevating structures above the floodplain, employing designs and building materials which make structures more resilient to flood damage and preventing floodwaters from entering structures in the flood zone, amongst other measures.

The primary objective of wetland restoration can be three-fold.  These projects can serve to reduce coastal flooding and erosion and can also provide new habitats and environmental benefits.

The term ‘wetland’ refers to a diverse range of shallow water and intertidal habitats, which occur in various locations around the world.  Wetland restoration relates to the rehabilitation of previously existing wetland functions from a more impaired to a less impaired or unimpaired state of overall function.

Floating agriculture is a way of utilising areas which are waterlogged for long periods of time in the production of food.  The technology is mainly aimed at adapting to more regular or prolonged flooding.

Flood hazard mapping is an exercise to define those coastal areas which are at risk of flooding under extreme conditions.  As such, its primary objective is to reduce the impact of coastal flooding.  However, mapping of erosion risk areas may serve to achieve erosion risk reduction.  It acts as an information system to enhance our understanding and awareness of coastal risk.

A flood warning system is a way of detecting threatening events in advance.  This enables the public to be warned en masse so that actions can be taken to reduce the adverse effects of the event.  As such, the primary objective of a flood warning system is to reduce exposure to coastal flooding.
