Dynamic Coasts comparatively analyzes existing designs built along coasts that seek to engage people with water to determine opportunities and implications for designers responding to both the revival of waterfronts and the implications of climate change. Structured as a series of comparative case studies, the research centers on visits to several European sites. Observation is primarily through time-lapse videos and plan sketches, while a contextual perspective is added through research and interviews with designers, care-takers, and historians. This study points to four factors supporting a successful, engaging,and well-used waterfront. At the broader level, infrastructure and culture profoundly influence who visits the sites, while at the site-design level, scaling and rearticulating the space and natural phenomena to a human scale is vital to bringing awareness to the dynamics of the coast.
