“…This research focused on slope estimation along the coast of Kuantan to Pekan with ten specific zones in which critically eroded. The sites are selected to be eroded (K1 category/Critical category) based on National Coastal and Erosion Study [9] and its relationship of coastal profile. This coastline area situated about 15 km to the South from Kuantan, Pahang and up to 30 km in the North.…”

The main concern for this research is slope estimation and the beach profiling with verification sensor-based remotely data (high spatial resolution). Thus, surveying and satellite extraction data need to be accurat. It had been proven to support the relationship between coastal erosion with beach slope changes along Kuantan, Pahang. Therefore, the actual coastline can be mapped from last vegetation features and determine physical condition of beach on coastal habitable land where the baseline has been changes due to sea-level rise event. Hence, the aim of this study is to monitor beach profile using high spatial resolution remote sensing imagery and GIS techniques to distinguish slope estimation from different sources in Kuantan, Pahang Site-verification are done to identify beach slope profiling along Kuantan coastline, Pahang. The objectives of this research are i) to generate coastal slope estimation and beach profile in year 2006 and 2014, ii) to quantify the estimated and observed beach slope from IFSAR data and slope site surveying (by NAHRIM) and iii) to visualise in 3-D view of coastal slope profile derived using IFSAR data. The accuracy values provided for the measurements made in open area, undisturbed area with slopes less than 10 %. From early reconnaissance of Kuantan beach, most of the area are flat and sandy profile to which are suitable for this application. Besides, we found out this method are reliable to produce appropriate slope profile along identified areas in selected Pahang coastline. The findings may indicated a better strategy for monitoring coastline changes is needed especially for vulnerable coastal erosion areas for future sustainable coastal management.

“…The coastal processes on the east coast of Peninsular Malaysia are influenced by the monsoonal system brought from East Asia, which delivers a high intensity of linked physical natural phenomena associated with current speeds, tides, waves, winds, and rainfall frequency during the winter season and has a significant impact on the cycle of beach erosion and accretion in Malaysia. Peninsular Malaysia has a coastline length of 1,972 kilometres out of a total length of 4,809 kilometres (Ehsan et al 2019;Gill et al, 2014;Mohd et al 2018;Razak et al 2018), and more than half of the Peninsular coast is eroding.…”

Coastal zones are vulnerable to the effects of nature and man, as well as being physically volatile. The interaction of hydrodynamic conditions in coastal areas is a complex phenomenon. Considering the characteristics in this specific area, understanding its hydrodynamic behaviour should be obviously clarified. Thus, the hydrodynamic characteristics for Kelantan coast had been simulated using a numerical software of MIKE 21 Hydrodynamic FM. To assess the performance of the model, a combination of time series analysis and statistical evaluation were carried out against two weeks of observed data. Time series analysis shows a good agreement with the field measurements for both magnitude and phase. Statistical analysis using Root Mean Squared Errors (RMSE) and Regression analysis (R 2 ) for current speed and water level were analysed. The results indicate that the RMSE for current speed are 8.97% and 8.00% for ADCP 1 and ADCP 2, respectively while the RMSE for water level is 8.89 %. Through the regression analysis, the output indicates that the numerical model is in a good performance as the R2 ranged from 0.72 to 0.9. Both time series and statistical approach were successfully utilised in the hydrodynamic model to determine the performance of the coastal hydrodynamic characteristics in Kelantan's coastline. The output model can provide important information, especially on the coastal management and landuse planning for the developers, planners and state authority.

Kelantan is a state on Peninsular Malaysia’s East Coast famed for its tropical jungle and seaside areas. Kelantan is a “flood-state” that encounters monsoons and tidal currents. Kelantan was devastated by tsunami-like floods in 2014 where it brought changes on its coastal geomorphology. Using a universal Digital Shoreline Analysis System (DSAS) technique, this study assesses shoreline changes along Kelantan’s coastline between 2013 (before the catastrophic flood) and 2021. A multipronged approach incorporating DSAS via GIS and satellite imagery were used to explore the coastline changes in Kelantan. This study found that Pantai Mek Mas and Pantai Kundur were the most sedimented and the most eroded area were around Pantai Cahaya Bulan, Kota Bharu respectively. The Shoreline Change Envelope (SCE) and Net Shoreline Movement (NSM) analysis concluded that the coastal area has the highest accretion rate of 177.07m/year and the greatest negative distance via NSM of -171.53m/year. The sedimentation along Pantai Mek Mas may happen due to the transportation of sedimentation via river flows from Kelantan River estuary and the degradation of shoreline along Pantai Cahaya Bulan may cause by the concentration of anthropogenic interventions. In conclusion, can be seen that the Kelantan’s coastal area shoreline does progressively proliferate over the past decade and the community vulnerability on the shoreline changes are at risk which comprehensive mitigation is needed to improve its resilience.
