Thematic data on the potential for lateral erosion reactivation following the removal of ripraps on the Allier River between 2017 and 2022

The data file contains a set of topographic, granulometric and planform analysis data for two reaches of the Allier River (France) that were studied following the removal of riverbank protections. The objective was to evaluate to what extent riprap removal may be an efficient restoration measure in terms of the reactivation of bank erosion and lateral channel dynamics as well as the replenishment of the local bedload. The dataset contains (1) digital elevation models obtained by LiDAR or photogrammetric surveys on site 1 between November 2017 and February 2022, and on site 2 between February 2020 and October 2022; (2) active channel planform analysis of site 2 and of the control reaches between 2019 and 2022 carried out from aerial satellite images and IGN orthophotographs; (3) granulometric data and their location in the channel and on the restored bank of site 2; (4) topobathymetric surveys and their comparison carried out on site 2 before the restoration work (2018) and after the restoration work in November 2021 and August 2022.
