Inlet Stability Solutions for Tributary Inflow

Abstract
Formulas in use relating to the flow of water through tidal inlets do not take into account the joint effects of inertia and tributary inflow that play a significant role in determining the characteristics of many inlets. In a proposed analytical model these two factors are considered where the tributary inflow to the bay causes ebb flow through the inlet to exceed flood flow. The solution method applies to the same type inlets as studied by E.I. Brown and G. H. Keulegan, i.e. inlets that have a bay in which the water rises and falls uniformly over the entire bay area. An additional assumption is that the discharge into and from the inlet is governed by a head loss that is quadratic in velocity.
