This thesis contributes to the development of numerical methods for flow and transport in porous media, in particular, by using space-time domain decomposition methods that enable the use of different time steps in the subdomains. In this work, we study two types of methods: one is based on a generalization of the Steklov-Poincaré operator to time-dependent problems and one is based on the Optimized Schwarz Waveform Relaxation (OSWR) method in which more general (Robin or Ventcell) transmission conditions are used to accelerate the convergence of the method. These two methods are derived in a mixed formulation, which is well-suited to problems arising in the modeling of flow and transport in porous media. We first consider the diffusion pro...
