Capacity of Inlet Outer Bars to Store Sand

Limiting slopes and depths at ebb-tidal shoals

“…In a different approach, Vincent and Corson (1981) developed empirical relationships among geometric parameters such as minimum depth of the ebb shoal, minimum inlet width, and area of the ebb delta, not considering hydrodynamic forcing. Walton and Adams (1976) showed that the equilibrium volume of the ebb shoal was also related to tidal prism by an equation similar in form to Eq. (1), which was further validated for inlets in Florida by Marino and Mehta (1987).…”

Long-Term Inlet Stability of a Multiple Inlet System, Pass Cavallo, Texas

“…Ebb shoal volume has been well correlated with tidal prism by Walton and Adams (1976), who concluded that ebb shoal volumes can be larger on coasts receiving less wave exposure, because there would be less transporting capacity to remove the sediment deposited by the ebb current. The following empirical formula was presented by Walton and Adams (1976) to compute the ebb shoal volume V E for inlets in equilibrium on mildly exposed (to waves) coasts.…”

“…The following empirical formula was presented by Walton and Adams (1976) to compute the ebb shoal volume V E for inlets in equilibrium on mildly exposed (to waves) coasts. The Galveston Entrance, TX, and Aransas Pass, TX, were among the 16 inlets analyzed to obtain this correlation:…”

Coastal Inlet Functional Design: Anticipating Morphologic Response

“…Because the formula of Walton and Adams (1976) relates tidal prism to ebb shoal volume, and M tot is closely related to the gross longshore transport in a year, the parameter r is directly connected with the characteristic time scale τ for inlet morphology change, bypassing, and suitability of the channel for navigation.…”

“…Empirical predictive formulas are available to calculate the volume of the ebb shoal complex (Walton and Adams 1976) and, with less reliability, the volume of the flood shoal (Carr de Betts 2000). These formulas are based on the tidal prism P, which is the amount of water entering through an inlet on ebb or exiting on flood, exclusive of river flow and wind-generated currents.…”
