Learning objectives

Principal processes of the river-coastal-ocean-atmosphere interface continuum (physics, biogeochemistry), measurements and instruments (physics and biogeochemistry) and main human/anthropogenic impacts. Precision, limits, difficulty of use in this complex environment, treatment solutions, algorithm and perspectives…

Calibration and validation of the satellite data used, complementarily between sensors (radars, radiometers, ect), complementarily with in situ observations (in situ, drone, ect) (link with the core courses), derivative products, modelling, Applications (see below).

Prerequisites

  • Maths/Physics/Chemistry (L3 and M1 Physics/Chemistry and M1 SOAC 1st semester)
    and/or
  • Biogeochemistry/Sedimentology (L3 and M1 Environment/Earth Sciences 1st semester)

Brief description of the course

Main processes, tools and analysis through some applications on human impacted land-ocean continuum. For example: Time series of water level, flow rate, extent of flood zones; Variation in water levels of rivers, exchange along the continent – river -lagoon – coastal zone – ocean; Salinization of coastal lagoon and infiltration of seawater, water and pollution (plastics, etc.);

Influence of tides, Natural disasters (earthquakes, fires, floods, tsunami, etc.), topography of foreshore areas, coastal sea level with combined tidal-storm-flood-wave effects, coastal erosion, sediment transport, productivity, eutrophication, anoxia, acidification, impact of coupling and retroaction with the atmosphere (rainfall, etc.), Management of resources in cross-border areas..
