The Dam Breach Module was developed to model tailings dam breaches using the output from a Tailings Deposition Model.
The Model is based on the Shallow Water Equations which are solved using the Finite Volume Method.
Flow is defined by the tailings rheology.
To activate the Dam Breach Module use the Module Selector.
Model features include:
•Newtonian and Non-Newtonian Flow Models
•A linear reconstruction to reconstruct gradients and improve model stability in distorted Elements
•A multi-dimensional limiter to suppress non-physical oscillations near discontinuities
•An implicit scheme utilising a Taylor series expansion to solve the Friction terms
•Several time integration schemes
•Several run control options
•View Dam Breach Result Surfaces at specified Time Intervals following a model run
Output comprises:
•Time
•Flow depth
•Flow velocities
•Flow flux
•Froude Number
