Wave-induced cross-shore sediment transport in the Ebro delta inner shelf

The near-bottom wave-induced cross-shelf sediment transport is one of the main mechanisms to maintain morphologically inner shelves. In opposition to suspended sediment transport by currents that controls fine sediment dispersal (and in consequence sediment deposits) in the shelf according to the am...
