We are thrilled to announce our first ever Webinar Series. We have collated a range of presentation topics to spark your interest covering contemporary New Zealand coastal issues like storm surge and climate change, through to the use of new technologies in localised coastal zone monitoring. Every month we will have an hour long free webinar that you can register for and then login, sit back, and enjoy. Keep your eyes open for each month’s webinar announcement.
Register here for the October Webinar
Date and Time: Wednesday 28th October, 2-3pm
Analysis of extreme storm-tide and skew-surge events around the coastline of New Zealand
We set out to understand the things contributing to the highest sea levels we get in New Zealand and whether there are patterns and if they are likely to occur in multiple places at once, or if they occur in close succession. These are issues that are important for emergency managers and insurance companies. We examined the spatial and temporal clustering of these extreme storm-tide and skew-surge events and identify typical storm-tracks and weather types associated with the spatial clusters of extreme events, from 85 extreme sea level and 135 extreme skew-surge events recorded in NZ since 1900. In this talk we explain how tides combine with storm surge, how the spring–neap tidal cycle prevents storm-tide events in close succession, the typical weather systems associated with extreme sea-levels and which areas of NZ they strike, and the surprising high sensitivity to the quite small mean sea level anomaly.
Aerial drones and their application within coastal zones for data collection
Most coastal investigations are expensive and complex to implement leading to the reliance on assumptions during the initial stages of projects. The presentation covers measuring currents in the surf zone using drones as well as other notable coastal features which were encountered during testing; this is to provide examples of where aerial drones can be applied to coastal applications to provide a cost effective and easily accessible means for data collection.
