To provide a precise sedimentary response of the Noumouzou coastal area (centre of the Ivorian coast) to extreme weather-marine phenomena on the Ivorian coasts, Radar Sentinel-1 images from 2015 to 2022 were used to evaluate the spatial and temporal sedimentary changes occurring in this area. In fact, digital processing of these radar images was carried out using geometric corrections, calibration and filtering using SNAP software. Field corrections made it possible to validate these Radar data through bilinear interpolation and the calculation of the digital elevation model. An evaluation of the evolution of the Radar backscatter coefficient was then carried out following the band calculations of the images acquired by highlighting the total power received (TRP) statistics of these images. The spatio-temporal sedimentary evolution is thus evaluated by considering the frequency in pixels of the Radar backscatter coefficients. Therefore, from 2015 to 2016, alternating episodes of erosion and accretions varying between 15.50 and 16.75 dB corresponding to a frequency in 10 pixels and between 12.25 to 14.75 dB corresponding to a frequency in 2 pixels were recorded respectively. From 2017 to 2018, sedimentary changes remained almost unchanged. However, from 2019 to 2020, erosive frequencies of more in 10.5 pixels located between 16 and 17 dB were notified, as well as significant enlarged spaces of up to 15 dB, reflecting extreme events occurring during this period. Between 2021 to 2022, it is rather a sedimentary balance that is recorded. A detailed analysis aimed at using only VV polarization data in the evaluation of the Radar backscatter coefficient could help to better appreciate the Radar response of the sediment evolution over the Ivorian coastal areas.
