are all important to a successful sediment transport model. Reference the RMA2
user's manual for the guidelines for obtaining a good hydrodynamic solution.
Issues Directly Related to Hydrodynamic Solution
Conservation of Mass Problems
Conservation of mass problems are a result of two issues: boundary break angles
along the perimeter of the mesh, and interpolation of the original incoming RMA2
time step.
