La sedimentaci\u00f3 als embassaments \u00e9s un problema cr\u00edtic i continu en la gesti\u00f3 sostenible dels recursos h\u00eddrics. Encara que els models bidimensionals (2D) convencionals s\u00f3n computacionalment eficients, ometen processos tridimensionals clau, com ara l’estratificaci\u00f3 t\u00e8rmica. Els models tridimensionals (3D) proporcionen una representaci\u00f3 f\u00edsica m\u00e9s precisa, per\u00f2 requereixen extensos recursos computacionals, fet que els fa inviables per a aplicacions a gran escala. Aquesta recerca desenvolupa un marc computacional que combina Computaci\u00f3 d’Alt Rendiment (HPC), Intel\u00b7lig\u00e8ncia Artificial (IA) i simulaci\u00f3 multif\u00edsica 3D avan\u00e7ada per a salvar aquesta escletxa.<\/p>\n
Un model hidromorfodin\u00e0mic bidimensional (R-Iber) es va reimplementar per a Unitats de Processament Gr\u00e0fic (GPUs), aconseguint acceleracions computacionals d’un a dos ordres de magnitud. El model accelerat va permetre l’entrenament d’un model substitut (surrogate) basat en Xarxes Neuronals Profundes (DNN), possibilitant una an\u00e0lisi de Monte Carlo de 100.000 execucions per a una calibraci\u00f3 robusta del model i la quantificaci\u00f3 de la incertesa. En paral\u00b7lel, es va desenvolupar un model multif\u00edsic tridimensional complet en l’entorn Kratos per a per simular el problema fluid t\u00e8rmic tridimensional.<\/p>\n
L’enfocament integrat es va aplicar al sistema de l’embassament de Riba-roja. Es va avaluar com l’estratificaci\u00f3 t\u00e8rmica afecta l’efici\u00e8ncia d’atrapament de sediments. Els resultats demostren que la combinaci\u00f3 d’HPC, IA i modelatge multif\u00edsic condueix a m\u00e8todes pr\u00e0ctics i aplicables per a la gesti\u00f3 sostenible d’embassaments.<\/p>\n
