Question

12. Give 3 functions of check dam​

Answer 1

Answer:

A check dam is a small, sometimes temporary, dam constructed across a swale, drainage ditch, or waterway to counteract erosion by reducing water flow velocity.[1] Check dams themselves are not a type of new technology; rather, they are an ancient technique dating from the second century A.D.[2] Check dams are typically, though not always, implemented in a system of several dams situated at regular intervals across the area of interest.[3]
