Webinar session ‘Assessing the role of coastal vegetation for wave attenuation using the MI-SAFE viewer’
The MI-SAFE viewer is developed in the FAST project ( Foreshore Assessment using Space Technology, http://fast.openearth.eu/) and is a valuable tool to assess the presence of vegetation and it contribution to wave attenuation anywhere on the world. Data on topography, bathymetry, vegetation cover and change, storm surge and wave statistics are derived from earth observation imagery, global databases and numerical modelling. Field data collected during the FAST project have been used to calibrate our model (XBeach) and its vegetation parameters. In addition to global, large-scale data, we have derived detailed and more accurate data for specific sites (Expert Level of services). Tailor-made solutions are offered to fit the user’s requirements for implementing nature-based flood defences.
The FAST project (Foreshore Assessment using Space Technology) has developed the MI-SAFE package to help meet this requirement. MI-SAFE is a combination of Earth Observation information and numerical modelling, packaged into open source and online products and services that demonstrate how coastal vegetation and foreshore areas can contribute to meet flood risk challenges. MI-SAFE information is based on the latest satellite sensor technology and big data analysis capabilities.
The MI-SAFE package combines existing and new earth observation data for coasts worldwide to estimate the contribution of vegetated foreshores towards coastal flood and erosion risk reduction. The MI-SAFE viewer gives a quick indication of the extent to which vegetation, when submerged during high tides, surges, or other high water level events, prevents coastal flooding and erosion. It does so qualitatively also for areas with little or no local data, drawing on open global sources of information. For locations for which more data is available, advanced services can provide specific quantitative information upon request. The MI-SAFE package works as a platform of services supported by a team of international experts. It delivers the capacity to explore multiple ecosystem services provided by vegetation and to incorporate these into coastal flood/erosion risk management decisions anywhere on the world’s coastlines.
