16 years of topographic surveys of rip-channelled high-energy meso-macrotidal sandy beach

Abstract: Sandy beaches are highly dynamic environments buffering shores from storm waves and providing outstanding recreational services. Long-term beach monitoring programs are critical to test and improve shoreline, beach morphodynamics and storm impact models. However, these programs are relatively rare and mostly restricted to microtidal alongshore-uniform beaches. The present 16-year dataset contains 326 digital elevation models and their over 1.635 × 106 individual sand level measurements at the high-energy meso-… Show more

“…For each approach, the ESM k +/− and respective parameters (a and b for Y09, and Φ for S14) are calibrated using the Simulated Annealing optimization technique [44] described in D'Anna et al [18] on Equation (4). Compared to D'Anna et al [18], who used the Truc Vert shoreline data up to 2017, the time series of mean shoreline position estimated here with topographic surveys is extended to the end of 2019 [45]. The calibration is performed over the period 01 January 2012-31 December 2019, which shows no long-term shoreline trend (Figure 7a).…”

“…Monthly-averaged significant wave height ranges from 1.1 m in August with dominant W-NW direction to 2.4 m in January with dominant W direction. Truc Vert beach has been intensively monitored since 2003 with monthly to bi-monthly topographic DGPS surveys, with additional daily topographic surveys and high-resolution bathymetric surveys collected during the ECORS'08 field campaign (Parisot et al, 2009), see Castelle et al (2020) for detailed description of the datasets. Since 2017, highresolution digital elevation model covering 4 km of beach-dune are also derived seasonally from photogrammetry of UAV images (Laporte-Fauret et al, 2019).…”

“…50-m depth, and have been extensively validated with field data (e.g. Castelle et al, 2020). The primary metocean variables used are: tidal elevation (η), significant wave height (H s ), mean wave period (T 02 ), wave direction (θ), temperature (T ), wind speed (U ), Insolation (I).…”
