In the\n   applications of this model, which include mineral processing and\n   wastewater treatment, the rate and composition of the feed flow cannot\n   be given deterministically. Efficient numerical simulation is required\n   to quantify the effect of uncertainty in these control parameters in\n   terms of the response of the clarifier thickener system. Thus, the\n   problem at hand is one of uncertainty quantification for nonlinear\n   hyperbolic problems with several random perturbations. The presented\n   hybrid stochastic Galerkin method is devised so as to extend the\n   polynomial chaos approximation by multiresolution discretization in the\n   stochastic space. This approach leads to a deterministic hyperbolic\n   system, which is partially decoupled and therefore suitable for\n   efficient parallelisation. Stochastic adaptivity reduces the\n   computational effort. Several numerical experiments are presented. (C)\n   2016 Elsevier Ltd. All rights reserved.",
