“…Amongst these various oceanographic processes, the long shore drifting currents which move all along the coasts play a vital role in changing the shapes and the morphology of the coasts/shorelines due to the phenomenon of erosion and deposition (Scott, 2005;Pradhan et al 2020). However, after the advent of modern satellite borne remotely sensed images, greater attention was given in studying the shoreline changes and there from the dynamics of the longshore currents (Saravanan & Chandrasekar, 2015;Abdelalim et al 2021). The interference of the human beings in the form of various developmental activities along the coast also do alter the shapes and the morphology of the shorelines.…”

The coastal zones always remain dynamically active with continued land building and land loss activities, as these form the provinces where various tectonic, fluvial, Aeolian, coastal and marine geomorphic processes interface with each other in varying dynamism and duration. Such morphological changes along the coasts do only control the environment of the coastal systems. In this connection, the east of India is unique with the complex tectonic and geomorphic processes, and thus the dynamically changing morphologies. Amongst various processes, the littoral currents are one of the dynamic processes along the east coast of India which move clockwisely all along the coast from Cape Comorin in the south to Andamans in the north during the non- northeast monsoonic months (Mar-Oct) and anticlockwisely from Andamans to down south of Tamil Nadu coast during northeast monsoonic months (Nov-Feb). This causes continued erosion and deposition all along the coast. This has been discretely seen in the form of rapid land growth in Vedaranniyam nose region in the centre and the land loss or erosion both in the northern and southern sectors of the Vedaranniyam nose region. The detailed mapping of the shorelines and the quantitative studies on the erosion/ deposition phenomenon from the shorelines of different periods deduced from the satellite Infra-red & Near Infra-red data of 1972, 1997, 2004,2006, 2009, 2016, 2018 & 2022 periods showed that the land has grown to an average area of 1.27 sq.km. from 1972–2022 in the central Vedaranniyam nose region with the land loss or the erosion on the northern and southern sectors. The Areal extent of the land growth was further visualised for every 500 years viz 2500, 3000, 3500 and so on. This indicated that, in the context of the current sea bed topography observed in GEBCO data in-between the Vedaranniyam nose and Jaffna peninsula, these two lands will get connected by a land bridge in another 10,000 or 12,000 years. Such land bridging will also lead to the formation of a caught-up sea to its south which may become a land in-between Rameswaram coast in the west and Jaffna coast in the east in course of time.

“…this study, we analyse the effects of wave climate on shoreline stability. Wave propagation modelling is used to study wave dynamics in shallow water(Mezouar et al 2021). The spectral wave model Mike 21-SW was used for simulating wave propagation in order to evaluate the pattern of wave energy distribution at the coast.…”

The coastal area of Sidi Madjedoub East to Oureah West is a very interesting and remarkable place. In the last 20 years, it is exposed to a series of natural and anthropogenic processes that generate short and long time variation. This research is based on the spatial-temporal analysis of the shoreline change along the coast between Sidi Madjedoub to Oureah, by using aerial photographs (2003) and quick-bird satellite images (2014 and 2023). The shoreline changes were calculated on 720 transects generated at intervals of 20 m. The Digital Shoreline Analysis System (DSAS) was used on the modelled shoreline. The results reveal that most of the area studied is undergoing erosion, with a mean rate change of -0.28 meters per year for the whole coast. In addition, numerical modelling of wave propagation was applied out using the Mike 21 model to get a better understanding of the influence of coastal hydrodynamics to shoreline change. This change in shoreline is principally due to human activities (sand mining, urbanization) and natural factors (currents, waves, storms). We can conclude that coastal morphology and the erosion and accretion of coastal zones are influenced by both natural and human activities.
