INRAE presentation

The French National Research Institute for Agriculture, Food, and the Environment (INRAE) is a public research establishment. It is a community of 12,000 people with more than 200 research units and 42 experimental units located throughout France. The institute is among the world leaders in agricultural and food sciences, in plant and animal sciences, and is 11th in the world in ecology and environment. INRAE’s main goal is to be a key player in the transitions necessary to address major global challenges. In the face of the increase in population, climate change, scarcity of resources and decline in biodiversity, the institute develops solutions for multiperformance agriculture, high quality food and sustainable management of resources and ecosystems.

Work environment, missions and activities

The candidate will join our multidisciplinary research team GHOSTE Gestion Hydraulique
Optimisation et Supervision des Transferts d'Eau focusing on optimal management of free surface
hydraulic systems, such as irrigation canals, dams or rivers systems GHOSTE gathers expertise in various scientific disciplines, mainly hydraulic and hydrology, optimization, automatic control and data
assimilation ( It is formed by researchers, engineers, PhD students and technicians, that participate actively in the development of simulation softwares such as the in house software SIC² (Simulation Intégrée des Canaux et de leur Contrôle http :://sic g eau net One of our major activities, is the spatial
hydraulics/hydrology, which aims at improving our knowledge of the worlds rivers through optimal use
of satellite information in a hydraulic network This requires solving inverse problems using adequate DA
techniques Several families of DA methods have been incorporated in SIC² Kalman Filtering, Particle
Filtering, and 4 D Var The Surface Water and Ocean Topography ( satellite mission, to be launched in spring 2022 will be the first mission to observe inland waters globally To prepare its launch, several algorithms, with different levels of complexity, have been proposed to NASA and CNES to produce the official SWOT discharge product Benchmarking experiments have been performed to assess the accuracy of the estimated discharge In this context, the successful candidate will join the SWOT Discharge Algorithm Working Group by testing and validating our discharge estimation algorithm « SIC 4 DVAR » in this benchmark framework The purpose is to generate an operational discharge algorithm that can be applied at the global scale and produce discharge estimates as accurate as possible The candidate main activities are prior to data assimilation, which include 1 processing information from different databases and satellites, 2 optimization of the existing code, such as parallel implementations, 3 running the algorithm on several benchmarks, 4 generalization of the code to the global scale
