Abstract
We consider the propagation of gravity currents (GC), through an array of vertical obstacles, called vegetation, along channels of power-law cross-section (CS) shapes. We formulate a model and solve it numerically. Special attention is given to the similarity long-term behaviour of the current, for which the analytical solutions are available and compared to the numerical data.
