Transfer of shader 2d water to the universal renderer.

Hello! I need to work on a project based on a universal renderer. The current task is to transfer the old shader to the shader graph. Shader is a 2d water visual with reflections of objects that are on the same layer as the water. And the scattering of objects that are on the layer, below the water.

I attached an open example of a shader working on an old renderer.

I hope you have a solution to implement it on the shader graph.
Thank you in advance.
