Preliminary River-Mouth Flow Model.
Abstract
Various interactions between freshwater river effluents and saline ocean waters are responsible for sediment dispersal and formation of bars at delta river mouths. River mouth bars exhibit a wide variety of geometries and controlling depths, and navigating these regions is hazardous because of the paucity of updated hydrographic charts and the fact that essentially no predictive capability presently exists. In addition, the interface between freshwater and saltwater masses is constantly changing, and such interfaces drastically affect acoustical transmission and reflections. The number of complex variables interacting in the mixing region is three-dimensional, and simultaneous monitoring of these parameters over large areas for any length of time becomes a near-impossible logistical task. This paper presents progress to date on mathematically simulating, in a three-dimensional array, the flow patterns, density concentrations, and sediment dispersal at a river mouth. (Author)
