“…The short-term data further highlight this mesoscale variability and show the seasonal cut-and-fill signature typical of the trade wind-wave-influenced French Guiana beaches during inter-bank phases (Dolique and Anthony, 2005), when mud banks do not affect the coast, or of many other tropical beaches with a well-defined seasonal trade-wind or monsoon wave regime (e.g., Tamura et al, 2010;Pereira et al, 2016;Anthony et al, 2017;Arrifin et al, 2018). The beach underwent significant sand loss (Figure 10; −14,579 m 3 ) in response to the high waves that prevailed between March and June 2018 (Figure 9A).…”

Multi-Decadal to Short-Term Beach and Shoreline Mobility in a Complex River-Mouth Environment Affected by Mud From the Amazon

On the 1500 km-long mud-dominated Guianas coast of South America, between the mouths of the two mega-rivers, the Amazon and the Orinoco, debouch numerous small rivers draining the humid tropical/equatorial Guiana Shield. The geomorphic development of the mouths of these rivers reflects interactions among water discharge, fluvial sediment load, and the alongshore migration of Amazon-derived mud banks alternating with inter-bank areas. The mouth of the Maroni River, astride the French Guiana-Suriname border, shows advanced estuarine infill and geomorphic development characterized by a western (downdrift) side comprising numerous recent cheniers and an eastern (updrift) side bound by an old (>2000 years B.P.) chenier. A multidecadal analysis of the beach bounding this chenier shows little net overall mobility notwithstanding significant decadal to sub-decadal variation. The overall stability reflects the diversion of sand supply from the Maroni River toward the downdrift coast and limited sand supply by the smaller Mana River further east, and the south bank of which was contiguous with this beach. The variability in beach multi-decadal mobility reflects the influence, on waves, of alongshore-migrating banks (strong wave dissipation, limited beach mobility) and inter-bank areas (limited wave dissipation, larger beach mobility), highlighted by a comparison, in the current bank phase, of offshore and inshore waves. Erosion of the beach between 2011 and 2017 coincides with the sealing of the mouth of the Mana by muddy progradation in 2011 and mouth relocation several kilometers eastward. The morphodynamics of the beach and shorter-term fluctuations in budget are related to: (1) interaction with estuarine sand dunes mobilized by strong tidal currents on the adjacent shallow shoreface, (2) the influence of the Maroni channel, and (3) rapid encroachment of the leading edge of the shore-attached mud bank on the eastern part of the beach. The beach morphodynamics and evolution highlight, thus, embedded levels of influence: the Maroni at the local scale, and the net westward sedimenttransport system and bank and inter-bank alternations that affect the Guianas coast at a regional scale. The recent erosion poses a threat to the local communities by reducing beach space available for recreation and turtle-nesting.

“…A 3 km coastal strip, stretching from Tok Jembal to Universiti Malaysia Terengganu (UMT) beaches in Kuala Nerus provenance was chosen as the study area ( Figure 1) due to its highgradient beaches (Ariffin, et al, 2018b;2019). Since 2010, after the extension of the airport runway at Tok Jembal beach, there was vast number of documented erosional events that have taken place along this strip (Ariffin et al, 2016;2018b in Tok Jembal had called for the construction of many series of ripraps/revetments to prevent further erosion (Ariffin et al, 2016;2018a;2018b).…”

“…Unfortunately, the ripraps/revetments at Tok Jembal had caused the erosion to move northward, towards the UMT beach. According to Ariffin et al (2018b), based on the failure of the previous mitigation plan, the Department of Irrigation and Drainage (Malaysia) carried out beach nourishment programme with a combination of breakwaters and groyne. The combination resulted in the formation of sand tombolo that slowly accreted behind the breakwater (breakwater 2 and 3) in front of the UMT beach ( Figure 1).…”

“…The Beaches are in a constant state of erosion, accretion and recovery in response to waves, currents, winds, storms and sea-level change (Muehe, 2003;Frihy et al, 2004;2018a;2018b). Active developments along poorly managed shorelines can potentially lead to property loss (Peterson & Bishop, 2005;Ashraful Islam et al, 2016;Ariffin, et al, 2018b;2019). A guideline prepared by the Department of Irrigation and Drainage, Malaysia, emphasises two methods by which shorelines can be protected: i) curative measure and ii) proper measure.…”

“…The tempests were responsible for the loss of nearly half of a newly constructed beach berm structure in 2004 (Nor Hisham, 2006). This situation is best explained by the fact that the northeast monsoon storms in the east coast of Peninsular Malaysia are significantly stronger compared to the southwest monsoon storms in the west coast of Peninsular Malaysia (Nor Hisham, 2006;Ariffin, et al, 2018a;2018b;2019;Yaacob et al, 2018).…”

Since 2008, Kuala Nerus has undergone rapid urbanization along its coastline, resulting in the loss of sand along the littoral zone. Due to the heavy erosion in 2012 at Tok Jembal beach that migrated to Universiti Malaysia Terengganu (UMT) beach in 2013, the Department of Irrigation and Drainage has implemented a coastal defence project to mitigate erosion by building a series of ripraps/revetments along the coasts. Additionally, breakwaters and groyne structures were built in combination with beach nourishment programme. For the sustenance of the local fishermen community, the Malaysia Public Works Department replaced one of the breakwaters to a jetty-type breakwater at Tok Jembal beach. Shoreline evaluations, beach profile measurements and numerical modelling were used in this present study to identify the effectiveness of combining the coastal defence and beach nourishment programmes. The combination of programmes successfully initiated the accretion of a ~30 m beach dune and created new beaches. However, erosion remains persistent in the beach that was unprotected and exposed directly to the South China Sea. We posit that a combination of coastal defence and beach nourishment programmes can potentially interrupt dynamic coastal processes, especially the current parameters.
