The main contribution is that the bottom topography effect is included in numerical fluxes and the bottom topography is discretized with an interface method in the same step.
本文的主要贡献在于，河床地势的影响被容入数值通量中，并且同时对河床地势采用连接面方法离散。

So it becomes very important to, when you're designing or modelling a reactor, understand the nature of what's outside the core and whether or not fluxes will peak in that zone.
