What Is The Potential Damages Of Future Climate Change Impact Of Flooding Risk

Decent Essays

Evaluated potential damages of future climate change impact of flooding risk by empirical method based and relies on statistical relationships between historical precipitation and flood damage. Changes in precipitation determined by general circulation models (GCMs). Future precipitation daily precipitation totals scenarios generated from an ensemble of GCMs, monthly average change output through SimCLIM (Randall et al., 2007) To evaluate potential damages of flooding by the statistical methods, relationship between observed precipitation and flood damages, these relationships to estimate future damages under a changing climate.
Increases in projected precipitation result of significant increases in damages. Projected in monetary …show more content…

There are a number of adaptation options that could be considered in order to reduce the risk of flooding to infrastructure in Greater Manchester, now and in the future.
Options to address fooding risk reduction under future climate change
Adaptation measures for flood risk reduction under future climate change
One of the three components of the risk formula, namely hazard, exposure and vulnerability
Increase of flood protection levels
It aims at reducing the vulnerability of people and assets to extreme stream flow conditions. It requires limited space as it normally consists of elevating the river banks, through permanent or temporary barriers, to increase the maximum stream flow that the watercourse can fully contain and convey downstream without causing damage (Lorenzo ET AL., 2016).This keeps the flood storage to minimulevels, hence thehe magnitude of the flood peak can remain unchanged for long river reaches.
Reduction of the peak flows
This adaptation option aims at reducing the flood hazard through a reduction and a delaying of peak flows during extreme events. Peak reduction is achieved by setting up areas within aside the river network that can be flooded in a controlled manner when the river stage reaches critical levels. In addition, peak flows are reduced by
