气体动力学模拟中的一个经典问题是卡宾现象的发生，即离散激波剖面的崩溃。我们发现，对于高弗劳德数，这也发生在浅水模拟。数值证据表明，普遍接受的治疗开发的数值的气体动力学也应工作浅水流动。
A classic problem in gas dynamics simulation is the occurrence of the carbuncle phenomenon, a breakdown of discrete shock profiles. We show that for high Froude number, this also occurs in shallow water simulations. Numerical evidence is given that commonly accepted cures developed for the numerics of gas dynamics should also work for shallow water flows.
