Post-doctoral position on erosion impact prediction

id="offer-description" class="ecl-u-type-heading-2 ecl-u-mt-none ecl-u-mb-l">Offer Description The BRGM Nouvelle-Aquitaine regional directorate's main purpose is to provide support to State services, operators and local authorities, as well as to carry out expertise or research actions in all fields of the Earth sciences, including for companies. You will be mainly responsible for exploiting the available optical satellite imagery (e.g. the Coastsat tool) to monitor descriptors of the morphological state of beaches and their evolution at event, seasonal and multi-annual time scales. A first task will be to set up a satellite image processing chain in order to produce an inventory of the satellite data available at intra-seasonal (winter) scales. On this basis, an analysis will be carried out of the potential for updating morphological indicators describing the state of the beaches and their ongoing degradation during the winter. This work will involve (i) detecting, recording and archiving storm impacts occurring during the winter (dune toe erosion); (ii) updating indicators of coastal morphology (position/shape of nearshore bars, beach width, beach slope, etc.) that can be used in the computation of storm impact forecasts. A second task will be to establish time series of shoreline positions (waterline and/or wet/dry line) in order to consider the calibration of equilibrium beach models (Splinter et al., 2014), making it possible to continuously infer, based on offshore wave
