Tidal inlets should be distinguished from tidal channels which connect open sea at both ends.In China, tidal inlets may be grouped into (1) embayment-lagoon type on sandy or rocky coast, (2) estua-rine inlets on the mouths of small or medium rivers which may be on mud plain coast, and (3) artificial inlets enclosed by breakwaters.Improvement of navigation channels of these inlets follows the same principle using O'Brien P-A formula.Where accurate oceanographical and littoral drift data are not available, a careful analysis of coastal morphology and sedimentology may provide a useful clue for the evaluation of the value of inlets in navigation.
