AB - <p style="text-align: justify;">We present a model for hyperpycnal plumes or turbidity currents that takes
into account the interaction between the turbidity current and the bottom, considering
deposition and erosion effects as well as solid transport of particles at the bed load
due to the current. Water entrainment from the ambient water in which the turbidity
current plunges is also considered. Motion of ambient water is neglected and the rigid
lid assumption is considered. The model is obtained as a depth-average system of
equations under the shallow water hypothesis describing the balance of fluid mass,
sediment mass and mean flow. The character of the system is analyzed and numerical
simulations are carried out using finite volume schemes and path-conservative Roe
schemes.</p>
