Coastal scientists are interested in tracking the surf-zones over time, so I spent some time exploring curve models to accomplish this. A generative curve model, positioned using a motion model driven by tidal dynamics, is able to track the changing shape and position of a stretch of coastline in Fish Hoek. The tracker struggles in storm conditions, but is able to regain track relatively quickly.
