The project department monitors and controls the whole process of breakwater enrockment costruction by field observing instruments buried in sand soft nappe.
The breakwater will contain sixteen hydro turbines, and as the tide rises, water rushes through the breakwater, activating the turbines, which turn a generator to produce electricity.
It pours powerfully out of the lagoon, driving the turbines in the breakwater in the opposite direction and again generating thousands of megawatts of electricity.
It was just a short swim around breakwaters which mark the border up one side and then down the other to reach Ceuta a Spanish government spokesman said.
Then, for three hours as the tide goes out, the water is held back within the breakwater, increasing the difference in water level, until it's several metres higher within the lagoon than in the open sea.
" It is so, Your Grace, " Arstan Whitebeard said. " The great cog Saduleon is berthed at the end of the quay, and the galleys Summer Sun and Joso's Prank are anchored beyond the breakwater" .
