Under what conditions would a submerged weir be preferable to a normal weir?
A submerged weir is preferable to a normal weir under several conditions:
High Flow Conditions: When flow rates are very high, causing the normal weir’s crest to be submerged, a submerged weir is designed to handle such conditions more effectively.
Variable Flow Control : It accommodates fluctuating flow rates better, maintaining effective water diversion even when flow levels change significantly.
Flow Measurement & Its Control: Provides more reliable measurements in varying water levels, as it functions effectively even when partially or fully submerged.
Erosion Control in Channel Bed: Helps reduce downstream erosion .
Sedimentation Management or control: Handles high sediment rates better, minimizing sediment build-up compared to a normal weir.
