Rapid Assessment of Morphology (RAM)

The RAM model is presently entering the final stages of development. For now, the model is in a rough state, but after being fully tested, the appearance and ease of use will see much improvement.


Excerpt from Draft CHETN:

Introduction: Morphology variations are the results of complex nonlinear interaction between flows and bottom sediments with many degrees and modes. It is characterized by nonlinearity and high dimensionality in its statistics. Consequently, finding a way to reduce the dimensionality of the spatial-temporal system of morphology area is a challenging task. In general, the morphologic dynamic modeling typically requires several modules to simulate complicated physical processes of morphology such as hydrodynamics, waves, sediment transport, and bottom updates. Dynamic modeling also requires substantial CPU time to simulate variables due to the limitation of CFL conditions associated with the numerical space and time integration. RAM has been developed to analyze temporal-spatial complex patterns as well as to reduce their dimensionality, and finally to predict morphology including physical processes of sediment transport using the most important patterns of morphology through EOF (Empirical Orthogonal Function) results.
