For this purpose, the SWAN model was calibrated based on one-year wave observations of Azeffoune buoy (Algerian coast) and validated against eleven wave buoys measurements through the West Mediterranean basin. For the calibration process, we focused on the whitecapping dissipation coefficient C-ds and on the exponential wind wave growth and whitecapping dissipation source terms. The statistical error analysis of the calibration results led to conclude that the SWAN model calibration corrected the underestimation of the significant wave height hindcasts in the default mode and improved its accuracy in the West Mediterranean basin. The exponential wind wave growth of Komen et al (1984) and the whitecapping dissipation source terms of Janssen (1991) with C-ds = 1.0 have been thus recommended for the western Mediterranean basin. The comparison of the simulation results obtained using this calibrated parameters against eleven measurement buoys showed a high performance of the calibrated SWAN model with an average scatter index of 30% for the significant wave heights and 19% for the mean wave period. This calibrated SWAN model will constitute a practical wave hindcast model with high spatial resolution ((similar to)3 km) and high accuracy in the Algerian basin, which will allow us to proceed to a finer mesh size using the SWAN nested grid system in this area.eninfo:eu-repo/semantics/closedAccessSwanWhitecappingWave growthSt6Mediterranean seaAlgerian basinExtreme sea-stateCoastal regionsWind reanalysesSurface-wavesSource termsPart IIDissipationEnergyPerformanceClimateEngineeringOceanographyWater wavesAlgerian BasinHigh spatial resolutionMediterranean seaStatistical error analysisWestern Mediterranean basinWhite-capping dissipationWhitecappingBuoysArticle0004593633000182-s2.0-8506007884022524184Engineering, oceanOceanographyWater Waves; Wind Stress; Oceans And Seas
