INTER-RELATIONS BETWEEN JET BEHAVIOR AND HYDRAULIC PROCESSES OBSERVED AT DELTAIC RIVER MOUTHS AND TIDAL INLETS

Charles G. Bates, John C. Freeman, Jr.

Abstract


Price (1951) has stated: "(in) geological oceanography as practiced today there is constant emphasis on quantitative measurement and quantitative theoretical development." As a demonstration of this geophysical approach to geological problems the authors have studied the theory of processes involved when sediment-laden water flows into a currentless, tideless, wave-free basin. The theoretical concepts developed have then been tested against the actual occurrences in nature. The result is that it is possible to propose a comprehensive theory of delta formation which may explain many of the features observed near mouths of rivers. According to this theory, there are three distinct and basic types of river inflow into a still basin, as shown in Figure 1:
