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...

What is the sinkhole mechanism under a leaked sewer pipeline in a non-krast area (areas with no carbonate rocks or lime stone)?

What is the sinkhole/subsidence/ ground collapse mechanism under a leaking sewer pipeline in a non-krast urban area (areas with no carbonate rocks or lime stone)? Because sinkhole also use to...

Which is more risky in case of sinkhole or subsidence of soil? Leaked underground sewer or water pipe with continuous or non-continuous flow?

if the flow of water in a leaked underground water or sewer pipeline is: 1) Continuous flow 2) Non-continuous flow (Cyclic flow) In both cases which case is more risky when it comes to ground...

Any wireless sensors which can measure the movement of soil when buried underground?

I am looking to monitor the subsidence of ground for that i want to place some sensors underground, so with the passage of time if there is any sort of movement or subsidence inside the soil...

What are the factors that may effect the propagation of data under soil to above soil?

i mean i i use any kind of sensor under ground then how soil will effect the data to gather above ground wirelessly.

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...
