Analysis of interaction between waves and cliff along the adriatic coast of Polignano (Apulia, italy)

The aim of this study is the analysis of the dynamic behavior of the rocky cliff located below the old urban center of Polignano (Apulia, Southern Italy). In order to characterize the behavior of the cliff under the impulse generated by sea waves, two types of measures were carried out on the rocky mass: (1) environmental vibrations and (2) accelerometer records. The first type of measures, has provided a recognition of the intrinsic and anisotropic dynamic behavior of the coastal cliff. The accelerometer records, carried out during heavy storms in December 2009 and January 2010, have allowed to confirm the results of previous measures and to evaluate the energy transfer from waves to cliff, in terms of maximum values and temporal distribution. In order to facilitate a correct interpretation of the measures, also a geomechanical characterization of the rocky mass has been carried out.
