 The final item to be addressed to complete the model setup is the 
-definition of the boundary condition. As 
-discussed in Section \ref{sec:methodology}, a Mw 9 event provides
-the tsunami source. The resultant tsunami wave is made up of a series
-of waves with different amplitudes which is affected by the energy
-and style of the event as well as the bathymetry whilst it travels
-from its source to Dampier. The amplitude and velocity of each of these
-waves are then provided to ANUGA as boundary conditions and propagated
-inshore.
+definition of the boundary condition. The tsunami source in this
+study is given as an initial condition, as opposed to a boundary
+condition to studies when the tsunami is generated by an undersea
+earthquake. Hence, the boundary conditions for this model will
+be Dirichlet boundary conditions, that is, all quantities are 
+given constant values. Here, stage and velocity at the boundaries
+are set to 0.
 
 Sea floor friction will generally provide resistance to the water flow
