? Sabo works mainly involve the construction of sabo dams (check dams) in remote mountain areas. Because of the principal locations of such works, the general public does not often see them and the necessity for and role of sabo works are seldom understood. If devastated mountain land is left unattended, however, the sediment discharged from this land raises the riverbed in the lower reaches, thus increasing the likelihood of flooding and sediment disasters.
Sabo works protect the lives of the public and national land from sediment disasters which devastate land with rich greenery, threaten precious lives and destroy houses, roads and railway lines by means of the construction of sabo dams and channel works.
