Erosion-deposition Prone Assessment Along the Kelantan and Terengganu Coasts Due to Sea Level Rise

Abstract The erosion-prone zone is characterised by nearshore sand formed the combined action of tides, wind, and recurring waves crashing on beach. By running perpendicular to coastline bathymetry, 51 cross-shore sections were chosen from a total 54 study longshore transport along beaches Kelantan Terengganu. hydrodynamic model was used determine water level, current speed, spectral density, while Spectral Wave Model LitDrift construct boundary wave variables Net Transport across each sector. output compared previously published zones in NCES Report (2015), results agreed. net transfer varies based angle coastline, direction waves, beach profile. ranges -693,000 m3/year 444,000 depending profile, direction, coastline. transit for section also calculated 2030, 2050, 2100, taking into consideration sea level rise. most recent IPCC assessment (AR6) applied generate SLR forecasts year 2100. According statistics, all are expected increase whereas only 53% 67% develop 2050 respectively. From 2030 2100 2020, Terengganu grows 9.5%, 10%, 4.5%, respectively.Net transportation grow until then steadily decline However, using better anticipated model, this inquiry can be improved.
