“…Regarding TELEMAC, exemplary reference can be made to the work of Brière et al (2007) on assessing its performance for a hydrodynamic case study; Brown and Davies (2009), Luo et al (2013) and Villaret et al (2013) on coupled wave/hydrodynamics-sediment transport/morphological modelling; Sauvaget et al (2000) on the modelling of tidal currents; and Jia et al (2015) on wavecurrent interactions in a river-and wave-dominant estuary. Regarding MIKE21, respective literature review would include the work of Siegle et al (2007) and Ranasinghe et al (2010) on coupled wave/hydrodynamics-sediment transport/morphological modelling, Babu et al (2005) on the modelling of tide-driven currents, Kong (2014) on the impact of tidal waves on storm surge and Aboobacker et al (2009) and ArıGüner et al (2013) on wave modelling. However, and given the fact that regarding system architecture and modelling components TELEMAC and MIKE21 have a lot of similarities (see also Sect.…”

Abstract. Numerical modelling has become an essential component of today's coastal planning, decision support and risk assessment. High-resolution modelling offers an extensive range of capabilities regarding simulated conditions, works and practices and provides with a wide array of data regarding nearshore wave dynamics and hydrodynamics. In the present work, the open-source TELEMAC suite and the commercial software MIKE21 are applied to selected coastal areas of South Italy. Applications follow a scenario-based approach in order to study representative wave conditions in the coastal field; the models' results are intercompared in order to test both their performance and capabilities and are further evaluated on the basis of their operational use for coastal planning and design. A multiparametric approach for the rapid assessment of wave conditions in coastal areas is also presented and implemented in areas of the same region. The overall approach is deemed to provide useful insights on the tested models and the use of numerical models -in general -in the above context, especially considering that the design of harbours, coastal protection works and management practices in the coastal zone is based on scenario-based approaches as well.

“…Therefore, with these measurements and the outputs of numerical modeling for the Caspian Sea and also satellite data, wave hindcast can be done for a long time. Aboobacker and his colleagues (Aboobacker et al, 2009) applied an MIKE21 SW model for eastern coasts of India and compared the results with measured data from May 1996 to January 1997. They found out that due to the high correction coefficients, i.e.…”

ABSTRACT:Numerical simulation results of wind wave in the Caspian Sea by using wind forcing data are presented. The numerical modeling which is applied in this study is based on numerical spectral wave model which is based on Navier-Stokes equations. It solves these equations through each of mesh elements. Moreover, in this model high-resolution unstructured grid for the Caspian Sea has been used in order to reach finer accuracy. The wind forcing data are given from European Centre for Medium-Range Weather Forecasts (ECMWF). The measurement data, which are gained from Ports and Marine Organisation (PMO) of Iran, are used in order to estimate the accuracy of the model. The results have shown better accuracy in comparison with PMO simulation. Mean of the coefficient of determination (R-squared) for significant wave height in this simulation is 0.8059, though, in PMO simulation this coefficient is reported 0.7056. Better accuracy requires more measurement data and also finer resolution of bathymetry data.

“…The wave spectra along the Indian coast are generally multi-peaked (Harish and Baba 1986;Kumar et al 2003;Rao and Baba, 1996) and occurrences of double-peaked spectra are more frequent during the low sea states. Wave spectra along the east coast of India during extreme events are single-peaked (Aboobacker et al 2009;Kumar et al 2004) and occurs when spectral peak period for fully developed sea equals peak wave period (Torsethaugen and Haver 2004). …”

Seasonal and annual variations in wave characteristics are studied based on measurements during 2009-2011 using wave rider buoy. Presence of swells generated by the south Indian Ocean cyclones are found over the south western Bay of Bengal during pre monsoon season. Maximum significant wave height is measured 6 m during Thane cyclone in December 2011. Long period waves are observed mostly during the summer (SW) monsoon and are negligible in the winter (NE) monsoon period. Short period waves dominate (63%) the wave climate during the NE monsoon. Wave spectra during the SW monsoon are multi peaked whereas during the post monsoon season single peaked spectra are found. Single peaked spectra observed during SW monsoon of 2011 coincides with the presence of positive Indian Ocean Dipole. Waves during the pre monsoon and SW monsoon season are influenced by sea breeze. Analysis indicates that directional width is minimum for waves from the NE since they are wind waves and maximum for waves from SE since they are swells. Study indicates that wave climate of the south western Bay of Bengal is in contrast to that in eastern Arabian Sea during the SW monsoon.
