How neural networking can be applied in sinkhole risk prediction, if i had the data already avilable?

I did various indoor experiments on sinkhole occurence due to leakage in underground pipelines in various soil profiles. I got data for all the experiments and now i want to apply neural...

Is there any equation, law or previous research, for ground subsidence due to water interaction?

I am looking for a numerical model, equation or law, which supports the ground subsidence due leakage in underground water pipelines or interaction of water and subsurface soil. Thank you

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...

I think that in a place where the flow is not continuous, since there is no time for the soil to settle.

May be you are right but i am not sure yet, still it's confusing.

It is a very interested question

Generally, the degree of flushing the soil away is proportional to the pressure of the leaking fluid and to the size of hole in the pipe.
