Hoist the flag: A boundary rip current case study on swimmer safety in the Scheveningen harbour area

Each year several fatalities due to rip currents are reported in the Netherlands. One of these accidents was during May 11th in 2020 near the Scheveningen harbour, were several surfers lost their lives. During the hydrodynamic and meteorological accident were quite severe, with a significant wave height of 3.0m and wind speeds of 11 m/s, which...

Sensitivity of rip current forecasts to errors in remotely-sensed bathymetry

Operational nearshore current forecasts based on numerical model simulations are gaining popularity as a measure to increase the safety of swimmers. Applying remotely-sensed bathymetry in these model simulations is often proposed in order to cope with rapidly changing nearshore bathymetry. Errors in the remotely-sensed bathymetry may...

Rip Current Prediction System for Swimmer Safety: Towards operational forecasting using a process based model and nearshore bathymetry from video

Rip currents are among the most dangerous coastal hazards for the bathing public, and contribute to the highest portion of beach rescues all over the world. In order to help life guards in planning and preparing rescue resources so as to minimize casualties, information about where and when rip currents may occur is needed. This can be provided...
