Reservoir Inflow Forecast System

The inflow forecasting system is an essential tool to assist dam owners in decision making and planning. Effective and optimized hydropower reservoir operation, monitor and forecast inflows and lake level to provide benefits in maximizing energy revenue, while taking into account dam safety risks.

The system offered by TNB Research consist of followings criteria;

  • Automated integration of Forecast rainfall

  • Forecast inflow and lake level in a reservoir up to 7 days ahead

  • Part of Reservoir Early Warning System

  • Integrate telemetry, SCADA and operation to allow fast and accurate Decision Support System

  • Enhancement to support reservoir optimisation

  • Rainfall forecast from a Numerical Weather Prediction (NWP) model

  • Telemetry - Real-time rainfall and river level measurements

  • SCADA - Real-time dam release and lake level measurements

  • Database Management System

  • Hydrology and Hyraulic Model

  • Storage Model


  • Improved water management : With a forecast system in place, reservoir managers can better predict future inflows and outflows.

  • Ability to plan for extreme weather events by alerting managers to potential flooding risks, allowing them to take proactive measures to reduce the impact.

  • Improved electricity generation by accurately predicting inflows, energy production can be optimized, helping to reduce costs and ensure a stable energy supply.

  • Enhanced safety.
