layer and slice

Hello,

I have an unconfined aquifer. The thickness of the aquifer is about 30m. I want to divide this layer into 10 slices.

I must affect conductivity to all slices or there are other a simplest way to do this?

the simplest way is to use the specific option of the function copy.

to create the 10 slice you can do this by fixing the first slice(ground surface) and adding 9 slice.
