Project abstract: Every year, hundreds of lifeboat and lifeguard operations occur to rescue coastal users who have become cut off by tide. Despite the RNLI’s best efforts there are still multiple fatalities.
Ultimately, to reduce the number of emergencies a deeper understanding of the reasons why coastal users become exposed to this hazard is required. This project will address this by looking at people’s concepts and understanding of the tide. Our goal is to help the RNLI develop precautionary measures in a more targeted way, responding directly to coastal users’ conceptual needs.
For instance, people will naturally generalise from previous experiences with the tide, not realising that tidal movements can differ radically between places and at different times. Furthermore, they will normally expect that the water will come in straight to the shore, not diagonally or in a curved or irregular fashion; they expect tide to come in quite slowly, and to be able to simply walk back on the sandbanks to the shore. However, the tide rarely just uniformly advances and retreats across a beach. Instead, it will initially flow laterally along channels and around sandbanks, cutting them off from the mainland and removing any safe route back to land.
