Answer 2

ANSWER:

Seepage through embankment in earthen dams is controlled by drain trenches.

EXPLANATION:

Drain trenches prevent the water from seeping through the body of the dam.  A drain trench is a floor drain that has a trough or channel shaped body. The drain trenches are used for rapid evacuation of surface water.

It is also used for containing chemical spill or utility lines. In other words, it is used to contain water that seeps in through the earthen dams thereby preventing the dams from damage.
