Job description

Offer DescriptionRemote sensing, particularly satellite-based, enables access to a wide range of data, tools, and services that can facilitate water resource management. For the Var River watershed (France), operational physically-based numerical models (hydrological, hydraulic, and hydrogeological) are integrated into a decision support tool (AquaVar), managed by the Eau d’Azur Authority (REA). These spatially distributed models require reliable input data/measurements (DEM, vegetation cover, soil moisture, etc.) that ideally reflect the spatial and temporal variability of the measured parameters. Integrating data from satellite remote sensing (especially for monitoring changes in snow cover or river morphology) is a priority to improve the input data for AquaVar models. Although many systems exist for measuring these key modeling variables, few are directly and systematically used by operational services. Due to a technical and transfer gap, such products are rarely available, and few spatially distributed hydrological models operate continuously on an entire watershed for real-time modeling. Access to and inclusion of remote sensing products could significantly enhance the quality of hydrological modeling. New monitoring indicators could complement traditional ones and reinforce predictive work (e.g., implementing scenarios for unconventional water reuse strategies, considering river morphology evolution, vegetation cover, and snowpack changes).This postdoctoral position is part of the “Act and Innovate for Water” (AIO) France 2030 – ADEME project, conducted in partnership with Xylem, Eau d’Azur Authority, and Université Côte d’Azur. Working within the “Risks on a Changing Planet” research team at the Geoazur laboratory and IMREDD, and in collaboration with another postdoc focused on hydrodynamic flow modeling, you will address these challenges by developing an operational methodology for integrating remote sensing data on the spatio-temporal evolution of hydromorphological features, snow cover, and other hydrological variables into the AquaVar decision-support system.In synergy with the research team (Geoazur) and IMREDD, local partners and stakeholders managing water resources (Régie Eau d’Azur, the local water utility), and another postdoctoral researcher working on hydrodynamic modeling , you will respond to the previous objectives by developing an operational methodology for including remote sensing data, notably on hydromorphological spatio-temporal evolution and snow cover for physically based digital models of the AquaVar decision support tool.You will map the available open-source data suitable for these objectives and critically analyze them for use in operational services. You will develop scripts to process satellite data (non-territorial) to generate dedicated digital indicators and cartographic products (particularly “snow” and “morphology” indicators from satellite images). Key areas of study include:

• Snow-covered area in the upper watershed (Var River),

• Potential sediment transport quantification, by assessing braided riverbed shifts using multi-year seasonal time series,

• Seasonal changes in soil moisture, vegetation cover, and evapotranspiration,

• Impacts of extreme hydroclimatic events (e.g., storms Alex, Aline, droughts),

• Transferability of methods to similar hydrosystems, tested on other watersheds.

Key Responsibilities : Share results and knowledge internally and externally, and, where necessary, support Ph.D. students and interns in their research projects.

• Publish findings in scientific journals.
