Dear sir,

I am facing a problem in which I have to find out the static, dynamic, and the safe yeild of water from a bore well.

for this I have been told that there are two bore wells of 6" thickness with a water pipe of 3" in them and are 550m apart. the drilled depth of the bore well is 150m.

can you please guide me as to how I can measure the top level of water suface continiously using any electric device or by any suitable manual method.

I am planning to do this analysis with the help of thiess method. will my analysis with this method for the above problem be correct.

Thanks ,
