Barrages (check dams)

By

Check dams act as barriers to swift creeks and gullies or usually dry pathways of concentrated surface runoff. They can be constructed in form of a sill or a step. The measure reduces the longitudinal slopes, serves the accumulation of surface waters and controls the velocity of the concentrated surface runoff during intense rainfall events.…

Regulation of torrent streams and gullies

By

This measure is usually carried out in form of sets of barrages built in a direction perpendicular to a stream’s direction. The aim of the measure is to modify the erosion and accumulation processes in torrent streams through the retention of water and eroded material, e.g. when settlement areas are at risk. It effect is…
