AB - <p style="text-align: justify;">Goal of this paper is to suitably combine a model with an anisotropic mesh adaptation
for the numerical simulation of nonlinear advection-diffusion-reaction systems and incompressible flows
in ecological and environmental applications.
Using the reduced-basis method terminology, the proposed approach leads to a noticeable computational saving of the online phase
with respect to the resolution of the reference model on nonadapted grids.
The search of a suitable adapted model/mesh pair is to be meant, instead, in an offline fashion.</p>
