Cascading rock irrigation channel

The cascading rock Irrigation channel is constructed with stones on rocky slopes to capture surface water runoff from the mountains and channel it to the valley floor, where it can be utilised for human use such as drinking water, sanitation, and irrigation.

The uneven surface of the rock channel slows the pace of the water, thus preventing scouring at the foot of the channel. The channel also provides a suitable environment for the cultivation of trees, which in turn can help reduce water and wind erosion on the slopes, preventing rock and debris movement onto the cultivated lands in the valley.
