“…Most parts of the west coast of Peninsular Malaysia are mudflats that are rich with diverse species of mangrove that promote the growth of marine life and play an important role in dissipating wave energy. The mangrove habitats along the coastline, which help to dissipate wave energy, has been destroyed and this has resulted in a rapid coastal erosion (Ehsan et al, 2019;Ghazali, 2006;Hashim et al, 2010;Lee et al, 2014;Stanley & Lewis, 2009). The study covers 276 km of the Selangor coastline and is divided into smaller units known as the Management Unit (MU).…”

“…On the contrary, in the west of Peninsular Malaysia the wind and wave action are moderate and less aggressive and thus serve as corrosion agents rather than an agent of deposition (Ghazali, 2006;Hashim & Noor, 2013;Jaharudin et al, 2019;Mohammad et al, 2007;Stanley & Lewis, 2009). The beaches in Selangor are not spared from both the natural process of coastal erosion and deposition (Ehsan et al, 2019;Razak et al, 2018;Selamat et al, 2017). As one of the most developed states in Malaysia, Selangor goes through a very rapid development process.…”

“…Most shoreline changes are regarded as a major dynamic change in coastal areas (Ehsan et al, 2019;Jaharudin et al, 2019;Mohd Azharn et al, 2018;Mohd et al, 2019;Rameli & Jaafar, 2018;Selamat et al, 2017;Stanley & Lewis, 2009), where the two main causes of shoreline changes are natural activities in the area and human activities.

“…In Peninsular Malaysia, the intrusion of seawater has caused damage to large areas of agricultural land and properties; public facilities and coastal roads have been destroyed and caused transportation delay. The intrusion of seawater has also caused damage to beaches and this have had adverse impact on the tourism industry (Ehsan et al, 2019;Ghazali, 2006;Hassan & Rahmat, 2016;Mohd et al, 2019;Rameli & Jaafar, 2018;Razak et al, 2018;Selamat et al, 2017;Stanley & Lewis, 2009, 2009.…”

Sea level rise is often associated with climate change and global warming. The change in shoreline is a continuous process that occurs through various processes such as erosion, sedimentation, sea level rise, wave behaviour and land use. Rapid technological advancement has made it possible to quickly identify the shoreline changes through a combination of Geographical Information Systems (GIS) application and Remote Sensing technology. The current study aims to identify the criteria or characteristics of the coastal areas and identify the risks for potential hazards in the coastal areas of Selangor. The data used in this study are the topographic maps produced in 1984 and SPOT 5 satellite images taken in 2013. The results of this study show that the estimated total area of erosion is 2,558 hectares and the total area of accretion is 2,583 hectares. The areas in Pasangan,

“…A rising sea level has been reported along the Malaysian coastline [50,51], and a corresponding increase in coastal hazards such as flooding and erosion have been observed in many coastal areas [52]. The coasts of Selangor and Batu Pahat have experienced severe coastal erosion, leading to the loss of 18.785 km 2 and 4.155 km 2 of land, respectively [53]. Similarly, coastal flooding in Johor has caused an economic loss of an estimated RM 2.4 billion and the destruction of RM 0.35 billion worth of amenities [53].…”

Assessing the Impacts of Rising Sea Level on Coastal Morpho-Dynamics with Automated High-Frequency Shoreline Mapping Using Multi-Sensor Optical Satellites

et al. 2021

Rising sea level is generally assumed and widely reported to be the significant driver of coastal erosion of most low-lying sandy beaches globally. However, there is limited data-driven evidence of this relationship due to the challenges in quantifying shoreline dynamics at the same temporal scale as sea-level records. Using a Google Earth Engine (GEE)-enabled Python toolkit, this study conducted shoreline dynamic analysis using high-frequency data sampling to analyze the impact of sea-level rise on the Malaysian coastline between 1993 and 2019. Instantaneous shorelines were extracted from a test site on Teluk Nipah Island and 21 tide gauge sites from the combined Landsat 5–8 and Sentinel 2 images using an automated shoreline-detection method, which was based on supervised image classification and sub-pixel border segmentation. The results indicated that rising sea level is contributing to shoreline erosion in the study area, but is not the only driver of shoreline displacement. The impacts of high population density, anthropogenic activities, and longshore sediment transportation on shoreline displacement were observed in some of the beaches. The conclusions of this study highlight that the synergistic use of multi-sensor remote-sensing data improves temporal resolution of shoreline detection, removes short-term variability, and reduces uncertainties in satellite-derived shoreline analysis compared to the low-frequency sampling approach.
