Les \u00e9changes entre les \u00e9coulements de surface et les \u00e9coulement souterrain sont un verrou technique important pour la mod\u00e9lisation des ph\u00e9nom\u00e8nes hydrauliques \u00e0 l’\u00e9chelle d’un bassin versant. On s’int\u00e9ressera ici uniquement au zone satur\u00e9e \u00e0 l’aide d’une mod\u00e9lisation verticalement int\u00e9gr\u00e9e.<\/span><\/div>\n

Il s\u2019agit dans ce projet, \u00e0 l\u2019aide du logiciel freefem++ (https:\/\/doc.freefem.org\/introduction\/index.html<\/a>), de r\u00e9soudre num\u00e9riquement les \u00e9quations de Richards en dimension 2, d\u2019\u00e9tudier la convergence du sch\u00e9ma et de confronter la solution num\u00e9rique au barrage de La Verne.\u00a0<\/span>

\n
<\/span><\/div>\n
En raison des \u00e9chelles de temps des \u00e9coulements en milieux poreux, on doit faire usage \u00e0 des m\u00e9thodes num\u00e9riques implicites. La forte non-lin\u00e9arit\u00e9 de l\u2019\u00e9quation de Richards coupl\u00e9 \u00e0 un solveur implicite est souvent d\u00e9licate. Il s\u2019agit dans ce projet de r\u00e9aliser une analyse num\u00e9rique pour construire une m\u00e9thode num\u00e9rique robuste que nous programmerons \u00e0 l\u2019aide d\u2019une m\u00e9thode El\u00e9ments Finis Discontinus dans une version simplifi\u00e9e de l\u2019\u00e9quation de \u00a0Richards.<\/span><\/div>\n

<\/span><\/div>\n
Il s\u2019agit dans ce projet de proposer un couplage entre les \u00e9quations de Saint-Venant et les \u00e9quations de Richards en prenant en compte les ph\u00e9nom\u00e8nes d\u2019infiltrations mais \u00e9galement d\u2019exfiltration. Ce type de mod\u00e8le peut servir de base pour le transfert de l\u2019eau dans les nappes au niveau du lac de Tchad, par exemple.<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
