dc.description.abstractCoastal structures, such as groynes and breakwaters, disrupt coastal processes and often promote sediment accumulation updrift and erosion downdrift. However, complex or different groyne designs, such as curved groynes can lead to different behaviours that are still poorly understood. This study investigated the short-term morphological changes caused by the construction of three sinusoidal groynes as a coastal restoration/defence measure at IcaraĆ­ Beach, Northeast Brazil. The methodology consisted of monthly field surveys using GNSS-RTK, UAS and high resolution CBERS-4A satellite imagery before, during and after completion of the defence structure. The results were compared with available wave data to provide a comprehensive understanding of the coastal behaviour. The curved shape of the groyne resulted in erosion and accumulation cells that were different (and in some cases opposite) to traditional structures. Beach formation and progradation was observed along a sheltered section of approximately 130 m of shoreline located downdrift, while severe erosion was recorded further downdrift, culminating in the partial loss of a property. The study highlights the challenges facing coastal protection measures and emphasises the need for sustainable solutions to mitigate future risks and prevent coastal degradation.eng
