The present work contributes to the characterization and mapping of sublittoral seabed located in the
nearshore of the San Andrés Beach in Malaga. This zone extends between the outer dock of the Malaga
harbor and the Guadalhorce river mouth. The study was done using the description of the acoustic reflection
patterns obtained with Side Scan Sonar thechniques. These patterns have been identified with lithological
changes, morphological features, dimension and orientation of bedforms, underwater patrimony and
evidences of the human activity on the seabed
