The sediment transport at a regional level along the southern coast of Texas has not yet been analysed in detail. In the existing literature, there is agreement that the net sediment transport direction along the coast of the south of Texas is northward along the coast of the Padre Islands. A numerical model is developed that computes the fully coupled waves, currents and sediment transport in the area using the open TELEMAC modelling system. The results of the model show that our prior understanding of the nearshore littoral processes was incomplete. The combination of stronger ocean currents during high wave events from the north results in a dominant southerly transport along most of the South Texas coast. Only in the northern half of Kenedy County are the residual transport rates to the north. So, where the literature assumes a drift convergence near Kenedy County, the modelling presented here identifies this area as a drift divide.
