Check Dam Ppt

Check Dam Ppt. PDF fileA check dam is a small barrier or dam constructed across a swale drainage ditch or other area of concentrated flow for the purpose of reducing channel erosion Channel erosion is reduced because check dams flatten the gradient of the flow channel and slow the velocity of channel flow Most check dams are constructed of rock.

Managed Aquifer Recharge (MAR) through check dams is the intentional recharge of water in the aquifers The objective of this paper is to present a review of research work carried out on the.

Reservoir Sedimentation and Its Control Water Engineering

A 10 mt check dam would cost Rs 58000 were as a 10 mt check dam as per the conventional design would cost 15 Lakhs to 2 Lakhs Life expectancy of Arch Butress check Dam is 100 years Horizontal thurst of water is resisted by the arch action of the arches which uniformly transfer the load to the butresses.

(PDF) A review on managed aquifer recharge by check dams

Heed (1976) developed following formula to determine the spacing of check dams – Spacing = HE/k tan θ Cos θ (412) Where HE = dam height measured from the crest of spillway to the gully floor k = constant its values are given as * For tan θ < 02 k = 30 * For tan θ > 02 k = 05.

Detailed design 6

A check dam is a small temporary or permanent dam constructed across a drainage ditch swale or channel to lower the speed of concentrated flows for a certain design range of storm events Check dams reduce the effective slope of the channel thereby reducing the velocity of flowing water allowing sediment to settle and reducing erosion.
