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。
the results show that shallow sea bottom topography mapping by sar is strongly related to radar parameters, sea states and bottom topography itself.
final, we proposed the detection algorithm of shallow ocean under water bottom topography in sar images, amongst it adopted average invariant moments and redefined distance of invariant moments.
最后提出了sar图像中浅海水下地形的检测算法,其中采用了平均不变矩并重新定义了不变矩的距离。
the guanhe river estuary, which has an irregular geometry and bottom topography complicated by the entrance bar, is open to the south huanghai sea (yellow sea).
