PORTFOLIO -

COASTAL ADAPTATION IN SEYCHELLES

ORCAS Consultants have been working in and around Seychelles since 2016. Our studies have looked at sites on the main granitic islands of Mahé and Praslin as well as at sites on the ecologically fragile outer atolls. These projects have generally been focused on better understanding the underlying causes of increased shoreline erosion and coastal flooding and on the design of sustainable solutions to manage these issues. We have partnered with agencies such as the UNDP, World Bank, SeyCCAT and the Government of Seychelles. Please visit our dedicated Seychelles coastal adaptation site for more information.

TSUNAMI EFFECTS IN PORTS

Waves and currents caused by tsunamis are a ubiquitous hazard to maritime activities and ports in particular. The historical record is replete with accounts from ship captains and harbour masters describing their fateful encounters with currents and surges caused by these destructive waves. Nevertheless, tsunami hazards remain largely under-appreciated in the port and maritime community. In response to this need, ORCAS consultants have developed port-specific warning and response products that can quickly and accurately assess the tsunami effects ports and harbours.

PROBABILISTIC ESTIMATION OF TROPICAL CYCLONE HAZARDS

Tropical cyclones are an unpredictable threat to coastal regions. These storms are complex, and a limited historical record makes it challenging to accurately assess the risks and develop design criteria. Our tropical cyclone model framework simulates thousands of years of cyclone activity to provide reliable estimates of cyclone-driven waves and storm surge on regional scales. Proven effective across the Indian and Pacific Oceans, ORCAS empowers communities and organizations to make informed decisions about coastal hazard management in tropical environments.

CONNECTIVITY MODELLING FOR MARINE PROTECTED AREAS

Our connectivity modelling work is advancing the science of Marine Protected Areas (MPAs) by simulating complex oceanographic conditions across large regions and over long periods of time. We develop 3D hydrodynamic models that are used to track how larvae of important species move between MPAs, helping to ensure these areas are functionally connected. By simulating a wide range of oceanographic processes, this research provides critical insights into the pathways and resilience of marine life, informing MPA network design and strengthening long-term conservation efforts.
