Qanat (subterranean channel) water profiles

[pingulii]

(First:my english speaking and writingis not good.sorry) i read a paper about Qanat water profile (Modeling of water surface profile in subterranean channel by DQM) and i have a question about it:
what is the application of subterranean channel water profiles? where is it usefull?in where?

Many communities in hot, arid climates depend upon qanats for their water supply. I imagine that knowing what controls flow rates, water depth etc in such systems would be important to ensure they are used with maximum efficiency. Perhaps you could provide a link to the paper you mentioned.
