| The cave river's course is channelled by the beds of limestone. A weakness in the rock can allow the river to increase its gradient and flow-rate, providing a real challenge for the cave explorers. The downward rush is halted when the water table is reached. Here the slow-flowing river carves tunnels with a more rounded profile. | |
| 石灰岩河床将洞穴的河道分割成千沟万壑。石灰岩薄弱处被河水冲刷差距的陡坡处水量激增，为洞穴探险带来相当的挑战。水流到达地下水位后便停止下流。这里缓缓流动的河流切割出一条圆形隧道。 |
