| Summary: | The prediction of the formation, spacing and
location of rip currents is a scientific challenge that can be achieved by
means of different complementary methods. In this paper the analysis of
numerical and experimental data, including RPAS (remotely piloted aircraft
systems) observations, allowed us to detect the presence of rip currents and rip
channels at the mouth of Sele River, in the Gulf of Salerno, southern Italy.
The dataset used to analyze these phenomena consisted of two different
bathymetric surveys, a detailed sediment analysis and a set of
high-resolution wave numerical simulations, completed with Google
Earth<sup>TM</sup> images and RPAS observations. The grain
size trend analysis and the numerical simulations allowed us to identify the rip
current occurrence, forced by topographically constrained channels incised on
the seabed, which were compared with observations. |
