The spectral third-generation ocean wind-wave model WAVEWATCH III (WW3), operational since January 2005 at the Department of Applied Sciences of the University “Parthenope” (Italy), was adopted for simulating wave propagation in the Gulf of Naples. The model was coupled with PSU/NCAR mesoscale model (MM5), which gives wind forcing at 1-h intervals. The model was implemented using a four-nested grid configuration covering the Mediterranean Sea until the Gulf of Naples, the inner mesh with higher resolution (1 km × 1 km). The simulated directional spectral waves were compared with APAT storm wave data recorded in winter 2000 offshore the Gulf of Naples and with wind and wave data collected by Servizio Idrografico e Mareografico offshore the mouth of river Sele in the Gulf of Salerno. The implementation of the wave model with reference to the December 2004 storm on the coastlines of the Gulf of Naples gives evidence of the need of a regional wind-wave model for this orographically complex area.

The sea states numerical modeling has been developed for years, it used for very varied fields such as the sizing of coastal work, the safety of navigation, the study of the stability of the beaches or the water leisure.  The spectral third-generation ocean wind-wave model WAVEWATCH III (WW3) software was adopted and developed for simulating wave propagation in the Mediterranean basin.  In this study, a more detailed study was carried out on the port of Algiers. Two different atmospheric models have been used to get the wind forcing: ALADIN (Area Limited Dynamic Adaptation Inter National Development) with an 8 km resolution. And AROME (Application to Operational Research at Meso-scale) with a 3 km resolution. The results obtained using both of the atmospheric models have been compared and analyzed.

This study is focused on the alterations and typical features of the wind wave climate of the Black Sea’s coastal waters since 1979 till nowadays. Wind wave parameters were calculated by means of the 3rd-generation numerical spectral wind wave model SWAN, which is widely used on various spatial scales – both coastal waters and open seas. Data on wind speed and direction from the NCEP CFSR reanalysis were used as forcing. The computations were performed on an unstructured computational grid with cell size depending on the distance from the shoreline. Modeling results were applied to evaluate the main characteristics of the wind wave in various coastal areas of the sea.

Fundamental Information

Hindcasted wind and wave data, available on a coarse resolution global grid (Copernicus ERA5 dataset), are downscaled by means of the numerical model SWAN (simulating waves in the nearshore) to produce time series of wave conditions at a high resolution along the Italian coasts in the central Tyrrhenian Sea. In order to achieve the proper spatial resolution along the coast, the finite element version of the model is used. Wave data time series at the ERA5 grid are used to specify boundary conditions for the wave model at the offshore sides of the computational domain. The wind field is fed to the model to account for local wave generation. The modeled sea states are compared against the multiple wave records available in the area, in order to calibrate and validate the model. The model results are in quite good agreement with direct measurements, both in terms of wave climate and wave extremes. The results show that using the present modeling chain, it is possible to build a reliable nearshore wave parameters database with high space resolution. Such a database, once prepared for coastal areas, possibly at the national level, can be of high value for many engineering activities related to coastal area management, and can be useful to provide fundamental information for the development of operational coastal services.

At Simon Fraser University, continuing education activities are developed and administered by the division of Continuing Studies working in association with the university's academic departments. The Applied Sciences Program, a Continuing Studies unit, was formed in early 1986 to parallel the new Faculty of Applied Sciences established in 1985 in a major reorganization of the University. This faculty is composed of the Schools of Computing Science, Kinesiology and Engineering Science plus the Department of Communication and the Natural Resources Management Program. The article focuses on the School of Engineering Science and their collaborative work with industry in continuing education.
