In a project for DVS ("Dienst verkeer en scheepvaart") of the Dutch Ministry of Waterways and Public Works ("Rijkswaterstaat"), Charta Software is developing a probabilistic tidal window determination model (PROTIDE). The model is developed to advise harbor authorities when it is safe for channel and tidal-bound ships to enter the harbor. It will combine geographical, meteorological and astronomical conditions to calculate a time window when the chance of touching the bottom is small enough. In the future the application PROTIDE will replace the currently used HARAP (harbor approach model).
The application is currently in a prototype state. The developments can be followed via http://protide.chartasoftware.com/.
