Two‐Layer Model of Saline Wedge. II: Prediction of Mean Properties
Publication: Journal of Hydraulic Engineering
Volume 113, Issue 10
Abstract
The theoretical formulations developed in part 1 for entrainment at the zero velocity line (ZVL) and for interfacial friction of the density interface have been implemented in a two‐layer model of the arrested salt wedge. Assuming constant densities in each layer, the equations are integrated numerically to predict overall wedge properties, including total intrusion length, the strength of salt circulation, wedge shape, and critical exit conditions. Good agreement is found with available data spanning the full Reynolds number range from laboratory to field conditions with relative intrusion lengths between orders This supports the theoretical development of part 1. Furthermore, the model documents the importance of including in wedge analysis the lower‐layer dynamics (bottom shear stress and convective effects) in contrast to the earlier Schijf and Schonfeld formulation.
