Check Dams From Massachusetts Erosion and Sediment Control Guidelines for Urban and Suburban Areas Description A check dam is a small dam constructed across a drainage ditch, swale, or channel to lower the velocity of flow. Reduced runoff velocity reduces erosion and gullying in the channel and allows sediments to settle out.
Gully control and catchment protection. Integrated gully treatment consisting of several simple practices including stone and wooden check dams, cut-off drains and reforestation in sediment traps. A combination of structural and vegetative measures was designed and implemented with the purpose of: (1) preventing affected areas from further ...
2.4 Gully treatment by grade stabilization structures. In gully control, temporary structural measures such as woven-wire, brushwood, logs, loose stone and boulder check dams are used to facilitate the growth of permanent vegetative cover. Check dams are constructed across the gully bed to stop channel and lateral erosion.
2 de nov. de 2022 · 4. Functions or Purpose The primary function of gully control structures is to provide safe passage to the flow through intervening into the prevailing slope of natural channel. The other purpose or function of gully control structures are listed below. To reduce runoff erosive forces by stacking off the gradient of a gully and by controlling ...
