TUFLOW HPC was released in September 2017. It is an explicit solver for the full 2D Shallow Water Equations (SWE), including a sub-grid scale eddy viscosity model. The scheme is both volume and momentum conserving, is 2nd order in space and 4th order in time. It uses a variety of control number stability criteria in an automated adaptive timestep framework to achieve unconditional stability (TUFLOW Classic doesn't include this feature). Over 12 months of development was dedicated to modelling accuracy and simulation speed for dam break assessments prior to its release and use on the 2017-2018 United Kingdom Reservoir Flood Inundation Study project (an assessment of the flood risk associated with all registered reservoirs in the United Kingdom - over 2000 in total). The speed and stability of TUFLOW HPC make it particularly well suited to dam break simulations. As such, even though TUFLOW Classic can be used in its own right, TUFLOW HPC is the recommended solver for dam break modelling. <br>
