Please look at these streamlines

Hi all.
From the internet, I found the following picture for streamlines of a solitary wave passing a submersed object.
Do you find these streamlines strange?
And I guess the streamlines for a traveling solitary wave without such a submersed object shall be similar for the upper part?

You are right... There is an analytic way to come with such behavior in ode's. It's called boundary layer.

Thank you for sharing the picture of the streamlines for a solitary wave passing a submersed object. After taking a closer look, I can see that the streamlines do appear to have some unusual patterns. The presence of the submersed object seems to have caused some disturbance in the flow of the wave, resulting in curved and intersecting streamlines.

I agree with your assumption that the streamlines for a traveling solitary wave without a submersed object would likely be similar in the upper part. However, the lower part may have a different flow pattern due to the absence of the object. It would be interesting to compare the two scenarios to see the impact of a submersed object on the flow of a solitary wave.

Overall, it is always fascinating to see the visual representation of fluid dynamics and how different factors can affect the flow patterns. Thank you for sharing this interesting image and sparking a discussion on streamlines.
