Abstract:

Safe navigation through tidal entrances requires a channel that neither migrates substantially nor shoals rapidly. Tidal entrances that exhibit such problems require substantial dredging or eventually become candidates for structural improvements. The US Army Corps of Engineers has considerable responsibility in the maintenance of navigation through many coastal waterways. One concern in the formulation of this research program was to improve the understanding of the stability of tidal inlets and the conditions that create inlet instability. The objective of this report is to summarize an investigation on the stability of selected US tidal inlets. Five broad tasks were 1 To develop methods for describing in a quantitative fashion stability characteristics that could be used to relate inlet stability to the morphology and hydraulics of inlet systems 2 To apply the methods to analyze the stability of a wide range of inlets in order to develop data bases on natural variations in inlet stability 3 To investigate a possible classification of inlets based on their stability characteristics 4 Analysis of interrelationships among various aspects of inlet stability and 5 Analysis of any regional variation in stability.
