Answer: The advantages of rubber dams are as follows:
- Since rubber is flexible in nature it is capable of performing deflation even in the presence of dirt and sedimentation on the downstream side. However, for rigid steel-gate dams, it may not be possible to open when there is excessive sediment.
- Since the foundation of rubber dams is comparatively lighter than that of steel-gate dams, it saves both construction cost and time.
- Rubber dams can be designed with longer spans without piers while steel-gate dams require intermediate piers for long spans.
