Bedform Phase Diagram. Between the bedform and the water surface figures prominently in this scheme. However subsequent work indicated that in-phase waves began to develop over the range 084 F 10. This phase diagram was a pioneer in the attempt to predict the bedform types seeking to relate data from average grain size d 50 with flows energy UĻ. Notice inconsistency with many bedform phase diagrams.

A complete re-evaluation of the nomenclature for combined-flow bedforms is proposed which includes their planform and crosssectional geometry in order to better represent the bed morphologies. Types of bedform lower plane bed ripples and dunes which with the concomitant calculation of hydrodynamic parameters mean velocity energy and mobility allowed the use of the phase diagram. Bedform phase diagrams are widely used in sedimentary geology because observations in core and outcrop usually do not permit more than a qualitative reconstruction of flow properties from sediment size and bedform dimensions. Southard and Boguchwal produced a series of 2-D diagrams using governing parameters that are not in dimensionless form. Figure 6 shows these parameters for tested density currents in the Simons and Richardson diagram indicating the incidence of most points in the prediction region of ripples.
