**5. Bagnoli Bay Case Study**

To assess the results carried out with numerical experiments, a small beach has been taken into account. It is located on the Bagnoli coast, West of Naples, in southern Italy (Figure 12). The beach is delimitated on the right (looking offshore) by a revetment which protects the road behind, on the left by a little mound and behind by a seawall which marks out the road; it extends for about 190 m from North-West to South-East. This little bay appears to be fundamentally governed by a single headland located on the left side, next to the drain of Bagnoli (Figure 13). The orientation of the downcoast section of the bay is approximately 210 ◦N and its distance from the diffraction point is approximately 47 m (Figure 13).

As will be demonstrated in the next section, the case study can be considered a static equilibrium bay governed by a single headland. For this reason, the application to the Bagnoli bay is of particular interest, as it allows us to verify the behaviour observed with numerical experimentation and to check the validity of Equation (15).
