Coastal flood maps, Marshall Islands, ARI100, SLR 0.5

Date modified: 30 June 2024

Coastal flood models for the Republic of Marshall Islands, showing flood depth in meters, for ARI100 (Average Recurrence Interval of 100 years, i.e. of a flood of such magnitude that it is projected to occur or be exceeded every 100 years), with 0.5 m Sea Level Rise (SLR). The flood models are modelled based on a modified 5m DEM created by NIWA and SPC as part of the PARTneR 2 project, available on Nexus.

Currently, only ARI100 with 0m, 0.5m, 1m, and 1.5m SLR is available on Nexus for Cook Islands, Republic of Marshall Islands, Samoa, Tonga, Tuvalu and Vanuatu. However, for all 6 countries, the models available are MHWS, ARI5, ARI10, ARI50, ARI100, ARI250 for 0 to 2m SLR in 0.1m increments. Please contact the NIWA or SPC contact for more information or access to these extra models.

These models were created using a bathtub modelling approach, so may have limited accuracy and for smaller areas of interest, hydrodynamic models should be used for decision making.
