drainage boundary
解釋

Could there exist another possibility for the south boundary of the system as follow : the rainfall infiltrates in the outcrop carbonate - mountain area of western, and moves towards south and deeper along carbonate rocks, then moves upper through the overlain tertiary system ( n ) with a thickness of 400m ( instead of running off to the springs and yellow river through a long approach of least hydraulic gradient ), and then mainly transforms into the horizontal drainage in the loess layer of quaternary, finally drains in lu - botan depres sion
