Analytical Model of Spit Evolution at Inlets
Abstract
The evolution of spits at inlets located on alluvial shores is examined from the perspective of process-based modeling. Hydrodynamic and morphologic processes controlling spit evolution are first identified and classified according to major spit parameter and time scale. An analytical model of spit evolution is then presented that describes cause and effect between selected spit parameters and the acting processes, focusing on spit elongation and its rate of change. Predictions and trends from the model are examined by reference to measurements of spit growth in Corpus Christi Bay, Texas, and to spits generated in a movable-bed physical model. It is concluded that considerable progress can be made in quantifying spit dynamics at inlets.
