WebBedform phase diagrams. Phase or stability diagrams are defined as graphs that show the regimes of existence of one or more stable bed states. The stability of the bed can be defined when the bedform is in … WebThe multicomponent aqueous systems with salts are rather less constrained by experimental data. As the number of phases increases with the number of components, the experiments and the visualization of phase diagrams become complicated. Of particular importance is the system NaCl−CaCl 2 − H 2 O—the reference system for natural brines, and the …
