Design and implementation of an innovative wind power system for beach erosion protection and nourishment

Abstract Beach erosion phenomena have become increasingly frequent and devastating with serious economic damage on tourism. A relatively recent technique of beach protection nourishment is based the creation along shoreline an unsaturated sandy zone, in which level phreatic surface lowered by means buried drains connected to electric suction pumps. The main problem encountered this solution need guarantee drainage when erosive activity maximum presence intense thunderstorms that often produce malfunction outage problems power supply. This paper shows realization a “green” totally mechanical design construction approach, achieved connecting 3.5-meter single-bladed wind turbine submerged axial pump optimized volute vertical shaft placed inside tower. system managed pitch controller studied for starting limiting exceptional winds.
