Introduction:
 
Real time systems allow decision makers to respond to short term variations in water resources where lead times for decisions vary from a few hours to a few days at most. Typical examples include:
 
  • Flood forecasting and the dissemination of flood warnings
  • Allocation of water to multiple users on a day to day basis
  • The day to day operation of hydro-power schemes
  • Reservoir management
 
Real time systems require the following components:
 
  • Monitoring stations with real-time capability (out-stations)
  • A real-time data acquisition system (telemetry)
  • Data management (database and quality control)
  • Forecasting models
  • A user interface
 
A schematic of a typical RTS for flood warning is shown below.

Applications in HP-II :
 
Bhakra Beas Management Board (BBMB)
 
One of the components of HP-II was the development of a Real Time Decision support System (RTDSS) for operational management of Bhakra Beas Management Board (BBMB). The objective of the RTDSS project is a Real Time Operational DSS in BBMB, incorporating a state-of-the-art data Real Time Data Acquisition System (RTDAS) using an advanced communication system for real time operational management of the Bhakra and Beas Reservoir.
 
The RTDSS integrates data from the RTDAS with data from external sources (e.g. weather forecast, snow cover, land cover and other global datasets), flow forecast modeling, optimization tools and analysis and decision support tools and makes them available through a user friendly interface.
 
The domain of the RTDSS is the area of the basins of the Beas and Satluj Rivers from upstream limits, including the area of the Satluj in Tibet to the downstream controls of BBMB at Nangal on the Satluj and Pong on the Beas. The DAS will monitor the catchment and rivers within India and the canals downstream to the state contact points. The key objectives of the RTDSS being to:
 
  • Minimise the loss and spill of water
  • Maximised the economic value of water
  • Develop optimal solutions for dam operators that balance short term and long term objectives

Real Time Streamflow Forecasting and Reservoir Operation System for Krishna and Bhima River Basins in Maharashtra (RTSF and ROS)
 
The state experiences flash floods particularly in the Western Ghats including the Krishna and Upper Bhima basins. Sangli and Kolhapur districts in Krishna Basin and Pune and Solapur districts in Bhima basin have experienced severe floods in the last decade.
 
Therefore, Government of Maharashtra has proposed to upgrade the existing HIS with real time data acquisition system (RTDAS) for Krishna and Bhima basins and to develop a real time stream flow forecasting (RTSF) and reservoir operation system (ROS) in the Krishna and Bhima river basins.
Following the Mid Term Review of World Bank aided HP-II (October 1-14, 2009), RTDSS for Maharashtra is included as a new component.
 
The RTDAS included the installation of new equipment to monitor rainfall, water level, river discharge, reservoir water level, reservoir outflow discharge and climatic variables. The system utilises a combination of INSAT and GSM/GPRS data communications to relay data in real time. A real time data centre has been established at Pune where IT hardware, databases and software have been installed.
 
The RTDAS contract was awarded to Mechatronics and the RTDSS to DHI. The RTDAS uses General Packet Radio Service (GPRS) modem transfer information from the out-stations to the RTDAS database. The outstations are powered by using solar panel with a 30 day battery backup and data loggers can store up to 12 months.The RTDSS has been developed using DHI software. NAM was used for rainfall-runoff and MIKE11 for hydrodynamic modelling and forecasting. The DHI RTDSS has been developed as the interface between the database, models and user with bespoke web pages for the dissemination of outputs. The RTDSS database is linked to the RTDAS database to allow the real time transfer of information.
