Data: Cutting the costs of coastal protection by integrating vegetation in flood defences.

File: levee_crest_height_reduction_per_country_version_July2021.nc Fields: (1) Crest height reduction m per km along the populated coastline susceptible to flooding (return period = 100 years) (2) Crest height reduction cost saving per country in million USD2005 PPP along the populated coastline susceptible to flooding (return period = 100 years) (3) Cost savings as percentage of GDP2005 along the urban populated coastline susceptible to flooding (return period = 100 years) File: transectdata_version_July2021.nc Transectdata of vegetated transects within the study area. Fields: (1) rps = return period (2) fid = id of the transects (3) centroids = coordinates of the transects (4) inun = (1) in area susceptible to flooding (5) urban = (1) in urban area, (0) not in urban area (6) veg_width = derived coastal vegetation belt width along the foreshore (7) veg_type = derived coastal vegetation type along the foreshore (1: salt marshes, 2: mangroves) (8) hsig = Offshore significant wave heights (multiple return periods) corresponding to the transects (9) wave period = Offshore peak wave period (multiple return periods) corresponding to the transects (10) surge = Extreme water level combination of surge and tide (m +MSL) (multiple return periods) (11) veg_z0 = elevation at the start of the vegetated zone (m +MSL) (12) hrms_end_noveg = root mean square wave height at the end of the foreshore (without vegetation) (multiple return periods) (13) hrms_endveg = root mean square wave height at the end of the foreshore (with vegetation) (multiple return periods) (14) pdens_15km = population density derived using buffer of 15 kilometre radius
