Post Body
After remaining completely closed for 10 years, this massive radial gate was finally put back into operation — and the footage captures exactly what a decade of neglect does to a dam structure. What starts as a routine gate-opening procedure quickly turns into a dramatic release of silt, pressure, and pent-up water.
A Decade of Silt Buildup Behind the Gate
With the gate shut for ten straight years, sediment had years to settle and compact against the upstream face. That buildup didn't just reduce storage capacity — it physically resisted the gate's movement, turning a normally routine operation into a slow, high-load struggle against packed silt.
Why the Gate Was Difficult to Open
The video shows the visible strain as the hoisting mechanism works against the accumulated sediment load. This is a common real-world challenge in radial (taintor) gate operation: long-term closure allows silt to consolidate against the skin plate, dramatically increasing the force needed for the initial lift compared to a gate in regular use.
The Turning Point: 2000mm Gate Opening
Water didn't begin flowing freely until the gate reached a 2000mm opening. Below that threshold, the compacted silt and the narrow gap kept flow choked back — but once the opening crossed 2000mm, the head pressure behind the gate finally found enough clearance to push through.
High Surge at the Gate Lip Crest
The most striking moment comes as a powerful surge erupts from the gate lip/crest — a sudden release of built-up hydraulic pressure combined with a decade's worth of disturbed sediment. This kind of surge is a textbook illustration of why long-closed spillway gates need to be opened carefully and incrementally, monitoring flow and structural load at every stage.
Why This Matters
This footage is a real-world case study in:
• Sediment management behind long-idle radial gates
• Hoisting load increases from silt consolidation
• Flow behavior and pressure release during gate reactivation
• Safe operational thresholds (like the 2000mm mark seen here)
Watch the full video to see the gate go from fully stuck to fully flowing.
