Exploitation of tidal power in the Bay of Cadiz: ancient tidal mills
J.J. Alonso del Rosario, J.M. Vidal Pérez, J. Pérez Serrano and J.C. Mendoza Sánchez

Tidal mills were the main industrial activity in the Bay of Cadiz for centuries. They were the last step in the production of salt and flour made by grinding grains. They were installed along the shallow channels, called “caños”, around the Bay, where the frictional and geometrical effects are very strong. The authors have analyzed the propagation of the semidiurnal tidal waves along the Caño de Sancti Petri and the available tidal power in the area. The ancient tidal mills were located where the available tidal potential energy is highest, which ensured productivity for grinding salt and wheat in ancient times. Some considerations about the possibility of installing tidal power plants in the Bay of Cadiz now are given, which show that it could be a real and renewal alternative source of energy for the area.

Keywords: ancient tidal mills, long shallow channels, tidal wave propagation.
