Des rivières et des hommes : hydrologie, hydraulique et géomorphologie (FUN)

Offered by Grenoble INP,
Des rivières et des hommes : hydrologie, hydraulique et géomorphologie  (FUN)

Comprendre et prévoir le comportement des rivières aménagées est un enjeu essentiel pour protéger les populations et préserver durablement les ressources en eau. Ce cours est illustré par de nombreux cas d'études.

Ce cours aborde la dynamique des rivières aménagées à partir d’exemples de terrain présentant un intérêt avéré tant pour les pays du Sud que du Nord (Bénin, France, Mexique, Vietnam, etc.).
Il doit vous permettre de parfaire et d’enrichir vos connaissances dans les domaines de l’hydrologie et de la qualité de l'eau, de l’hydraulique et de la géomorphologie fluviale, appliquées à la gestion des rivières.
Il vous propose des savoir-faire méthodologiques et techniques pour évaluer l’état des cours d’eau et envisager des interventions transposables aux différents environnements au Nord comme au Sud.

A l’issue de ce cours, vous devriez pouvoir :

  • décrire les mécanismes fluviaux essentiels et calculer les conditions d’écoulement en rivière (prédiction des débits, calcul des profondeurs d’eau) au moins par des méthodes approchées,
  • poser correctement les problèmes : menaces qui pèsent sur la rivière, menaces que la rivière fait peser sur les riverains (en particulier risques d'inondation)
  • acquérir une autonomie et une créativité accrues grâce à une meilleure appréhension de votre contexte de travail.

Le suivi du cours et la délivrance des attestations sont gratuits.

Innate Immunity (FUN) FUN
Institut Pasteur

Innate Immunity (FUN)

More than a century ago, Elie Metchnikoff established the bases of cellular innate immunity when he discovered the mechanism of phagocytosis. However, during most of the XXth century, adaptive immunity (also known as specific immunity) focused most of the interest of the researchers, until Charles Janeway and Polly Matzinger revisited the definition of immunology. What was called “non-specific immunity” was renamed “innate immunity”, and the understanding of the sensing of the exogenous or endogenous dangers signals, and their identification revolutionized our understanding of the early mechanism aimed to defend the integrity of the host against any type of attacks including pathogens.
