Abstract
A low-dimensional transport model which emphasizes the competition between two turbulent relaxation mechanisms, namely profile relaxation and nonlinear mode coupling, is proposed. When decreasing the relative weight of this mode coupling, transport exhibits a transition from diffusive to avalanche-like regimes. The latter plasma turbulent transport can prove to be very powerful in describing experimental evidence, especially concerning transient dynamics.Keywords
