Hi, greetings
I'm trying to make a model just like gif file bellow, making the waves is easy and I have no problem with it but I don't know how to make flat part in gradient way.
I'll be thankful if you help me for making this model.

There is a vex function called lerp(). Basically you group half of the area and mix in the displacement points for the group.

Or, you can make a simple volume box, and ramp it's density along that axis.
You can plug it into the ocean setup, and it uses it as a mask to mult down the effect.
Very handy way of fading down the waves naturally as it's multing down the spectrums.

Ooh you may be doing like above, just using the mountain or a noise.
You can make a wrangle that takes the relative bounding box of the axis your water is traveling down,
and use that in a ramp, then you have freedom to adjust the falloff.

Also easily doable without any VEX needed

Indeed, well, it's still using VEX 100% inside though isn't it hehehe.

Undeniably. But Houdini is ultimately being compiled into machine code, and yet here we are, clicking on screen, like a bunch of animals...

The new suite of attrib SOPs are great, really removes the need to get dirty with VEX.

Thank you for replying, can you please share the script? it's not working for me, I followed your instruction and didn't work, there is properly something wrong with my model.

Sure thing. Here's a scene, attached below.

And if you need to quickly see what was changed in a node, you can always click the Search and Filter button, and choose Parameters with Non-Default Values:
