STEPS
Shift+A -> Mesh -> Landscape
Subdivisions X/Y = 312
Noise Type = Turbulence
Random Seed = 213
Noise Size = 0.75
Depth = 12
Effect Type = Rings
Falloff = X
Properties -> Modifiers -> Subdivision Surface
Simple
Viewpoint = 2
Go into Edit Mode
A -> U -> Unwrap
Go into Object Mode
Properties -> Materials -> Add New Material
Shift+A -> Input -> Geometry
Shift+A -> Input -> Texture Coordinate
Shift+A -> Vector -> Mapping (x2)
Shift+A -> Vector -> Normal Map (x2)
Shift+A -> Texture -> Image Texture (x6)
Shift+A -> Converter -> Separate XYZ
Shift+A -> Converter -> ColorRamp
Shift+A -> Shaders -> Principled BDSF (x2)
Shift+A -> Shaders -> Mix Shader
Geometry Normal output to Separate XYZ Vector input
Separate XYZ Z output to ColorRamp Factor input
ColorRamp Color output to Mix Shader Factor input
ColorRamp black/white arrows at roughly 0.780
