We are looking for motivated candidates available to start in spring 2024, with skills in morphometry, LIDAR data processing and/or numerical modelling applied to surface processes .
The application website will open in January but in the meantime please do not hesitate to contact us if you are interested (stephane.bonnet@get.omp.eu).
Best regards,

18 to 24 months post-doc: River lateral erosion from terrestrial Lidar data, fluvial terraces and numerical modelling
The post-doctoral position is part of the French National Agency for Research (ANR) « WIVA » project (http://wivaanrproject.fr/), which aims to establish a law of lateral erosion of rivers and thus to better model the evolution of valley widths. The post-doctoral work will consist in quantifying and modelling recent lateral erosion of a meandering bedrock river (Rangitikei river, New Zealand), at a short (decadal) and intermediate (centennial to millennial) time-scales. Decadal erosion will be measure by analysing 14 yrs-long time series terrestrial Lidar data of Rangitikei valley flanks acquired on five sites alongstream since 2009 (see Lague et al., 2013 (doi: 10.1016/j.isprsjprs.2013.04.009)). Centennial to millennial erosion will be estimated by analysing the geometry of dated Holocene fluvial strath terraces (see Bonnet et al., 2019 (doi: 10.1038/s41598-019-44533-4) and Guyez et al., 2022 (doi: 10.1002/esp.5357)). Finally, these data will be used to constrain law of lateral erosion and river widening using the River.lab (ex EROS) numerical model (see Davy et al., 2017 (doi: 10.1002/2016JF004156)). The ability of the candidate to efficiently handle high-resolution topographic data and numerical models and to work with different and up-to-date quantitative methods will be essential.
The host team is located at the University of Toulouse, in the Geosciences Environnement Toulouse (GET) laboratory, under the main supervision of Stéphane Bonnet and Sébastien Carretier (WIVA project PI). The post-doc will work closely with Dimitri Lague (Lidar) and Philippe Davy (modelling) at Geosciences Rennes laboratory, remotely and during short journeys on a regular basis. These teams are internationally renowned for their use of Lidar in geomorphology, fluvial geomorphology and experimental and numerical modelling of landscapes and surface processes. The post-doc will be in close contact with the other members of the WIVA project, at GET, GR, CRPG (Nancy) and CEREGE (Aix en Provence), who make up the WIVA project consortium. In addition, the geomorphologists and other scientists in these structures offer an uncommon disciplinary and multidisciplinary environment for a young geoscientist.
Candidates are expected to have PhD in Earth and/or Environmental Sciences and to be trained in Geomorphology and/or Geophysics and/or Quaternary Sciences, with skills in morphometry, numerical modelling applied to surface processes and/or LIDAR data processing. Abilities to work in a collaborative environment, to communicate scientific research to diverse audience and to write scientific papers are expected. Proficiency in spoken and written English is required. Prior knowledge of French is not mandatory.
