Question

In assortment of dams in drainage channels, what are the main advantages of using rubber dams instead of steel-gate dams?

Answer

Key Advantages of rubber dams are as follows-
(i) As rubber is bendable in nature it is capable of performing depression even in presence of dirt and sedimentation on downstream side. Though, for rigid steel-gate dams, it might not be possible to open when there is extreme sediment.

(ii) As foundation of rubber dams is reasonably lighter than that of steel-gate dams, it saves both construction price and occasion.

(iii) Rubber dams are able to be planned with longer spans without piers as steel-gate dams require intermediate piers for long spans.
