Godavari Circle

The Godavari Circle is functioning with its headquarter at Hyderabad under the Administrative Control of Superintending Engineer, Godavari Circle, KGBO, CWC, Hyderabad. The Circle comprises of two Divisions viz., Upper Godavari Division and Lower Godavari Division at Hyderabad and their 7 Sub Divisions (including a Mechanical Sub Division at Hyderabad) for managing the works at 31 Hydrological Observation Sites, 41 Wireless Stations. There are 63 Rain Gauge Stations in the jurisdiction of Godavari Basin. There are 18 Flood Forecasting Stations in Godavari Basin including 3 Flood Forecasting Stations in Wainganga Basin and one Level-II + Water Quality Laboratory at Hyderabad and 6 Level-I Water Quality Laboratories at different sites. There are 63 Telemetry stations installed in Godavari Basin.


FUNCTIONS UNDER GODAVARI CIRCLE:
  1. Hydrological observations:
    Planning, establishment and carrying out hydrological observations through a network of Gauge and Discharge Stations in Godavari Basin and its Sub-Basins (excluding Pranhita Sub-Basin) spread over 5 States viz., Andhra Pradesh, Karnataka, Maharashtra, Chhattisgarh and Orissa.

  2. Compilation and storage of data:
    The basic data of gauge, discharge, suspended sediment & bed material and water quality collected at sites are processed at various levels and published in the form of Water Year Books (1st June to 31st May).

  3. Water Quality Data:
    24 water quality parameters including Physico-chemical, Biological and Bacteriological parameters are analysed monthly.

  4. Flood Forecast and Warning:
    Flood Forecasts and Warnings in Godavari Basin and Wainganga Basin are formulated and disseminated to the local authorities enabling them to take timely action to minimize the flood damage. The flood forecasting network comprises of 61 wireless stations (including Wainganga Basin), has been installed for communication of Flood Forecasts, out of which 20 are under Lower Godavari Division, Hyderabad (including control room at Hyderabad), 21 are under Upper Godavari Division, Hyderabad (including control rooms at Aurangabad and Nizamabad), 18 are under Wainganga Division, Nagpur (including control rooms at Nagpur and Chandrapur). Wireless sets have been installed at 59 stations for communication of river gauge and flow data on real time basis for Flood Forecast purpose. There are 14 Level Forecast stations (including 3 at Wainganga Basin) and 4 Inflow forecasting stations under Godavari Basin.

  5. Flood Forecasts of Rivers and Inflow Forecasts for Reservoirs:
    There are 18 flood forecasting stations in Godavari Basin, out of which 4 are flood inflow stations (Reservoirs) and 14 are flood level stations (river forecast stations) controlled by 3 Control Rooms and 24x7 schedule.

  6. Modernisation of Flood Forecasting in Godavari Basin:
    Installation of Telemetry Equipments.
    Under the X Plan, Scheme under "Establishment and Modernisation of Flood Forecasting and Inflow Forecast" is being implemented to upgrade the data communication with latest satellite based Telemetry System. By this system, data will be automatically observed by various electronic/electrical sensors and will be transmitted to the INSAT/METSAT and in turn will be relayed back to Earth Station. These data will be processed at the Earth Station and will be re-transmitted to Modeling Centres through V-SAT Communication link. The scheme re-named as Flood Forecasting will be continued in the XI Plan also.
    Data will be transmitted automatically through Telemetry System to the computers at the control room. Mathematical model (up-graded version of MIKE-11) will be used for routing the base station flows and generating runoff due to rainfall from the intermediate catchments.
    There are 63 stations identified for installation of Telemetry System of which all the 63 stations have been installed and Data from these stations is being received on real time basis. The stations transmit hourly water level and rainfall every fifteen minutes. Real time data from Telemetry is also additionally being used for flood forecasting purpose from the year 2009 onwards. Two modeling centers at Bhadrachalam and Hyderabad are also functioning in Godavari Basin.

  7. Other Activities:

    * Association with Central teams:
    Association with central teams for flood/drought damage assessments.

    * IWIN samples:
    Samples collected from four Water Quality Stations one under Upper Godavari Division and three under Lower Godavari Division of this Circle are sent to Physical Research Laboratory, Ahmedabad (Gujarat) every month.
