UCB Moorea Class: Biology and Geomorphology of Tropical Islands

Geomorphological changes occur on a range of spatial and temporal scales. In the past, they have been primarily driven by abiotic factors like storm events and wave action. More recently, human impacts have begun to affect geomorphological processes. It is critical to understand where and how humans impact such processes in order to minimize environmental impact of activities like boating and adding infrastructure. I studied human impacts on the formation and continuous alteration of Motu Tiahura, Mo'orea, French Polynesia. By studying velocities, sediment distribution, beach profiles and wave heights in areas with and without human activity, it was found that humans are in fact having a geomorphological impact on Motu Tiahura.
