Stability of Tidal Inlets: Use of Hydraulic Pressure for Channel and Bypassing Stability

Per Bruun, John Adams


This paper reviews briefly existing procedures and methods of channel stabilization and bypassing.The objective in all cases is to achieve an even, non-interrupted stability of the channel in its full length and a reliable, continuous and economical bypassing which retains an essential part of the longshore drift material. Modulation of inlet sub-bottom hydraulic pressures are shown to increase bed load transport, to create major offshore traps, and to transport sand by fluidization to bypassing pumps.
