Enabling integrated operation
To help our client improve flood management operations, we developed the Real-Time Streamflow Forecasting and Reservoir Operation System (RTSF & ROS). The web-based and user-friendly real-time decision support system – developed using MIKE 11 (now MIKE HYDRO River) as its foundation – includes:
- a hydrological rainfall-runoff model
- a hydraulic river routing model based on a fully dynamic solution of St. Venant’s equations (used to model transient open-channel flow and surface runoff)
Combined with information and communications technology, our state-of-the-art decision support system can help water authorities:
- analyse complex hydrological -meteorological problems
- manage the water resources of the river basins
- manage flood risks
The RTSF & ROS utilises the information collected from 300 telemetry stations in the Krishna and Bhima River Basins. These stations provide real-time data on rainfall, reservoir water levels, gate positions, river water levels and discharge, as well as other climatic parameters.
The system’s hydrological, hydrodynamic and real-time flood forecasting modules then utilise the collected data to help authorities monitor and forecast streamflow, as well as manage the operations of the 46 reservoirs in the basins.
As part of the project, we also developed a knowledge base system (KBS)– driven by MIKE OPERATIONS – for the Krishna and Bhima River Basins. Fully integrated with the RTSF & ROS, the KBS includes comprehensive historical hydrological and GIS data. The KBS imports and validates the real-time data, then converts the data into time series formats to run our reservoir operation and forecasting models. These are then archived in the KBS for future use.
