Hydropower multipurpose dams integrate sturdy ductile iron parts designed to maximize energy generation efficiency. Their durable metal construction ensures long-term resistance to wear and corrosion. These dams support sustainable, reliable hydropower infrastructure with minimal downtime.
A hydropower multipurpose dam must balance power generation with other water-management needs, such as flood discharge, irrigation supply and downstream releases. BIC supports the water-control portion of small hydropower and multipurpose dam projects through hydraulic structure assessment, gate selection, engineering coordination, installation and commissioning.
Hydropower output depends on available flow and net head, while dam operation must also account for flood levels and required downstream releases. Gate operation should therefore be planned around seasonal inflows, the target upstream water level, turbine intake conditions and the design flood discharge. During high-flow periods, safe release capacity takes priority; during normal operation, controlled water levels can support both generation and planned water use.
The appropriate gate system depends on the river width, retaining height, operating water levels, sediment conditions and control requirements. BIC’s hydraulic elevator dams and inflatable rubber dams can be evaluated where their operating characteristics suit the site. Final selection should follow the project’s hydraulic design and safety requirements.
To assess a proposed application, please provide the project location, river width, upstream and downstream water levels, seasonal flow data, design flood discharge, required retaining height, foundation conditions and intended hydropower operation. BIC can then review the water-control requirements and discuss a suitable equipment and engineering scope.
For an example of gate-based flow control serving both flood management and generation, see BIC’s Tongren Hydropower Station renovation project.
