The discovery that the "arrow" of Valdelagrana, (in El Puerto de Santa María, Cádiz, Spain) a small tongue of land that separates the Bay of the floodplain, is divided in two by a "caño" (channel natural seawater), called "Caño del Bote", and on the other extreme, by the "caño del Caserón". The main caño (the caño del Bote), which crosses the tongue of land and connects the San Pedro river (which is nothing but an arm of the sea, old mouth of a river (Guadalete river), with a strong current in the sea at high tide) with the beach, and short the arrow. The formation process of the caños (because of the strong erosion by water) has been very short, about two years. Also reflected in this work, that there are several hubs of communications (roads, rail) in the Bay of Cadiz, where the sea is about to arrive with high tide.
