  11. It is found that : ( 1 ) for linear slope, redistribution of incoming energy flux in modenumber space depends on both the modenumber of incident waves and the ratio of the slope of incident wave ray to slope of topography ; both the transmitted and reflected energy flux ( only for supercritical linear slope ) focus near one or two modenumbers ; for supercritical linear slope, the energy flux scattering to higher modenumbers becomes larger and the energy flux to lower modenumbers becomes smaller as the slope of incident wave ray comes near to slope of topography ; ( 2 ) for convex slope, energy flux is redistributed in wide - range modenumbers and also show peaks on lower - modenubers and higher - modenumbers ; ( 3 ) for concave slope, energy flux is also redistributed in wide - range modenumbers, but does not show peaks on higher - modenumbers as supercritical linear slope and convex slope do ; ( 4 ) the total energy flux scattering to higher modenumbers is approximately equal to the total energy flux to lower modenumbers for internal waves propagating over both convex slope and concave slope, which means the concave slope is the same efficient to convex slope in scattering energy flux to higher modenumbers ; ( 5 ) for convex slope, the wave ray reflected from near - critical topography can extend to deep ocean and shallow shelf, while for concave slope, the wave ray reflected from near - critical topography can only extend to limited distance, then meet the topography and be reflected again ; generally the shear of the internal waves reflected twice from concave slope is not enhanced while the enhanced shear does also appear before second reflection takes place, the enhanced shear can bring about intense mixing, so internal waves reflected from concave slope can also produce marked mixing near critical slope
