The main object of study of this thesis is the development of artificial diffusion shock capturing techniques for continuous and discontinuous Galerkin (cG and dG) approximations of the convection-diffusion problem. Special emphasis is given to the fulfillment of the Discrete Maximum Principle (DMP). Two artificial diffusion techniques are proposed for the transport problem in cG. They scale the corresponding artificial viscosity according to the variation of the gradient of the discrete solution between elements and one of them is proven to be monotonicity preserving. Both methods are used in combination with linear stabilization to enhance its performance; in particular a novel symmetric projection stabilization technique based on a loca...
