Abstract :
Novel optical fiber sensors for monitoring the dynamic variations of the sea bed level in the nearshore were developed. The sensors are based on fiber Bragg gratings embedded in a polyurethane resin. For this solution sensitivities of 0.50±0.02 nm/m were achieved. The sensor was tested under controlled laboratory conditions and during an observational survey on the Algarve (Portugal) coastline.
