“…Model B is based on WAVE-L, an HMS equation [82] simulator developed by members of the author team (from Aristotle University of Thessaloniki) for the propagation of nonlinear monochromatic waves over a rapidly changing, uneven seabed [83]. It incorporates shoaling, refraction, diffraction, (partial and total) reflection from (sloping and vertical) structures [84], energy dissipation due to combined wave breaking [85], and bottom friction [78,86,87]. Makris et al [18,79] have analytically presented the latest versions of the model that treat quasi-irregular wave generation and propagation [88,89] with any incident wave direction following the manipulation of lateral boundaries by Lee and Suh [90], based on Vincent and Briggs [91].…”

“…Model B (WAVE-L) has been upgraded from its previous versions [78,86,87] and its performance has been previously evaluated, both fundamentally by experimental data in laboratory flume scales and practically by field data in the Thessaloniki port area [17,18,79]. The encouraging model results referred to wave penetration and diffraction through port entrances (breakwater gaps) and roundheads of semi-infinite jetties or refraction due to shoaling bed formations.…”

This paper presents a recently developed Operational Forecast Platform (OFP) for prevailing sea conditions at very important ports worldwide (Accu-Waves). The OFP produces reliable high-resolution predictions of wave characteristics in and around ocean ports. Its goal is to support safer navigation, predict possible port downtime, assist vessel approaching, enhance management of towing services, and bolster secure ship maneuvering in busy ports around the globe. Accu-Waves OFP is based on integrated, high-resolution wave modelling over the continental shelf and in coastal areas that incorporates data from global- and regional-scale, open-sea wave and ocean circulation forecasts as boundary conditions. The coupling, nesting, calibration, and implementation of the models are reported and discussed in this paper, concerning 50 selected areas near and inside significant port basins. The detailed setup of the Accu-Waves OFP and its sub-system services is also provided regarding three-day forecasts at three-hourly intervals. The validation of the wave forecast system against in situ observations from wave buoys in coastal areas of the USA, Belgium, and Spain, as well as other model predictions by established OFPs, seems very promising, with performance skill scores ranging from adequate to very good. An exceptional case of stormy seas under severe marine weather conditions with very high wave maxima (>10 m) in the port of Algeciras is further discussed, confirming the good performance of the Accu-Waves OFP.

“…Some blisters have been managed by the Ministry of PUPR. However, abrasion remains to transfer to other parts of the coast, so a comprehensive clarification is desired to address this problem [3][4][5][6][7]. Way Hawang Beach is approximately 250 meters away from West Sumatra Causeway.…”

Way Hawang Beach, one of coastal tourist attraction, located in Way Hawang Village, Maje, Kaur Regency, Bengkulu Province is suffering from erosion. The regular erosion speed is approximately 2 to 3 meters/year, taking the distance from Way Hawang coastline to West Sumatra Causeway which around 250 meters. Efforts to eradicate abrasion on Way Hawang Coast are mostly carried out using coastal protective structures. One of the breakwater structures that can reduce wave energy is geotextile tubes, which is a low-threshold breakwater structure. Geotextile tubes create a synthetic barrier along shorelines and beaches to help control erosion. Geotextile tubes placement plays an important role in the overall protection system performance. The geotextile tubes are simulated in the abrasion and accretion positions on the Way Hawang coast. The simulation results indicated that the position between abrasion and accretion are the most effective position to manage and to avoid erosion in Way Hawang coast’s area at Bengkulu Province.
