Why such holes are formed when we put water on a plate

What is the relation can be derived between h(height of standing water) and r(radius of hole).(if P₀ is atmospheric pressure,σ is surface tension between water and container,σ₀ surface tension between fluid molecules,μ being coefficient of static friction,g acceleration due to gravity and ρ₀ is fluid density and any other constant if required)?

What all forces we need to consider while solving this problem.

As a first guess it will be the result of surface tension of the water , and irregularities on the plate allowing bubbles to form when the water is poured.
