This research investigates a digital workflow for simulating and visualizing the impact of extreme storms on the coastal landscape, and for testing the effectiveness of landscape designs intended to mitigate the sustained damage caused by these storms. We discuss the methods used to visualize increasing sea level heights and shoreline erosion using two and three-dimensional digital modelling software, and the methods used to create animated simulations of wave behaviour during coastal storms based on historic storm data. This paper also includes the creation of a digital landscape design which aims to mitigate the impacts of sea level rise, erosion, and storm surge in a simulated environment, visualizing the potential for restoration of lost ecologies through relocation of coastal water bodies to an inland area. The results show that the use of digital tools can uncover critical impacts of climate change on the coastal landscape, providing a useful framework for testing design mitigation of these problems.
