English: DEFENSE FROM HIGH WATERS WITH ENERGY PRODUCTION AND WATER OXYGENATION This scheme of plant, certainly would have been a valid alternative to the Mose of Venice from the economic and environmental point of view that the Italian ruling class is completing after twenty years of studies and many scandals, with the expenditure of about six billion euros, according to the latest estimates published in the newspaper "Il Sole 24 Ore". Instead of creating a work Pharaonic like Moses they could take lower only waters of the urban channels urban artificial water flows, one-way, which flow into the sea by means of hydraulic lifting due to the simple hydroelectric plants operated throughout the year, after reduction of the passage section of the channel, by means of small gates submerged, that leave only the height necessary to the passage of boats. In fact, if we consider the channel to be protected as the basin (wlb) and raise the water to the tank overflow (wddr), the water that comes out of the overflow tube (dthdc) is discharged into the sea while producing energy with the turbine (ht). This plant not only produce energy, but also ensure a continuous supply to the stagnant waters of the urban zone, reminiscent enough water sewer. Obviously, can be done precise calculations flow rates the direction of flow within the channels, in function of passage ports and the size of pumps and turbines, it being understood that in the event of exceptionally high waters the passage opening of the channels could be, further reduced with submerged gate. It is no exaggeration say that a fifth of the costs incurred for the Mose would be solved in addition of high waters problem, also the issue of the renewal of the water, equally important, simultaneously producing clean energy, which should not be unwelcome. The same scheme can be used for lifting groundwater producing hydroelectric energy.
