Mathematical model in hydrology: numerical solution and optimal data assimilation


Lunedi' 12 gennaio alle ore 11 in aula 2BC/30 TA, Mario Putti del Dipartimento di Metodi e Modelli Matematici per le Scienze Applicate, terrà un seminario dal titolo "Mathematical model in hydrology: numerical solution and optimal data assimilation".

Hydrology studies the flow of water in natural systems, from river catchments to aquifers, as well as the transport of contaminants. In this presentation I will discuss the most common PDE based mathematical models of use in hydrology, describing their main characteristics and the difficulties that are encountered in their practical solution. I will address the issues of spatial variability of the coefficients of the PDEs, that are intrinsic in these simulations because of the heterogeneous structure of natural porous media, and the issue of data assimilation, i.e. techniques to optimally incorporate external observations of the solution into the simulation models. I will focus on numerical solution methods describing open problems that need to be addressed in the context of real world simualtions.

Il seminario sarà preceduto da un prologo introduttivo dalle 10 alle 10.30 in Sala Riunioni VII piano e da una pausa di conversazione con caffè e biscotti in Sala Comune VII piano.

Rif. int. M. Bardi, F. Cardin, M. Putti, F. Rampazzo
