This study is designed to provide timely and actionable geospatial information for the management and planning in the coastal zone of Mangaia Island. The project will enhance the capacity of the Cook Islands to adapt to climate change and climate variability in selected coastal areas. Work includes the collection of nearshore bathymetric data, andtopography, the collection of oceanographic data and wave inundation modelling.The field work component of this project including the collection of oceanographic, bathymetric and topographic baselines to support assessment and modelling has been completed by OIP. A technical report outlining this data has been drafted and NIWA, with whom we are collaborating on the delivery of this project are now responsible for thewave and inundation modelling component which is currently underway.
