HydroSlide®

River Flow Control

The HydroSlide range of flow regulators are frequently used in the control of flows from rivers,
streams and attenuation dam structures. As a variable orifice control, it will control flows to
the desired pass forward flow rate (PFF) throughout the head range. This optimises downstream
capacity and minimises upstream attenuation volumes.

The use of HydroSlide controls also helps simplify dam wall structures reducing cost
of construction.

HydroSlide units are available in orifice sizes of 100 mm to 2500 mm diameter, controlling flows from 2 l/s to 10,000 l/s.

Advantages and Benefits

  • Maximises permissible downstream flows
  • Adjustable to ±30% from design flow
  • Minimises upstream storage through constant discharge
  • Simplifying design and construction of dam structures
  • Manufactured to meet any design flow requirements
  • Non-powered mechanical control
