*         HYDROLOGY UNIT: 

                To assess Water Resources in Karnataka State in a scientific manner, the studies of flow data at various points in different river basins and rainfall data are most essential.  As such, the Government of Karnataka has established a separate Hydrology Unit under Water Resources Development Organisation, with the responsibility to collect data from various gauging stations spread all over the State for analyzing and validation of Hydrometric and Hydrometeorological data.

 The following Meteorological stations are working under the Jurisdiction of WRDO:

 A.            Hydrological Stations: 


                1.             Current Meter Gauging Stations                                                       -               32

                2.             Stage Discharge Stations                                                                   -               10

                3.             Silt and Sedimentation observations stations                                  -               21



B.            Hydrometeorological Stations:


                1.             Fully Climatic Stations                                                                      -             87

                2.             Autographic Rain gauge Stations                                                      -             197

                3.             Standard Rain gauge Stations                                                           -              758




             The data obtained from these Hydrological and Hydro meteorological stations are scrutinized, analyzed and processed. The data of Rain gauge Stations maintained by Water Resources Development Organization are published by the Department of Economics and Statistics after obtaining the data from the concerned Tahasildar office’s of the respective Taluks. The yield studies are being carried out for the irrigation, drinking and power projects. H.M.datas are being sent daily to KSNDMC.


             Water resources Department has taken up identification of unrepresented area where there are no rain gauge stations & HM stations. The proposals are being examined as per the IMD norms at Division office &Circle office for setting up of new rain gauge stations & HM stations for accurate data collection.


             This unit is collecting and compiling the rainfall data and flow data of our State regularly. This data is being used for carrying out water availability studies for the newly proposed projects which are being proposed by planning unit of Water Resources Development Organization. The yield is being revised for the existing projects whenever needed. This unit is carrying out the hydrological studies of the new projects whenever it is required. Apart from this, data are being given to the users on their request.



The Hydrology Project Phase - I was taken up with World Bank Assistance and the project became effective in Karnataka State on 10.12.1996. The project was implemented over a period of seven years and ended on 31.12.2003. The project was implemented by 9 states and 5 central agencies. 


The object of this project was to set up a well-designed network in the country for collection of Hydrological and Hydro meteorological data both for Surface Water and Ground Water, in respect of quality and quantity. With this data, user-friendly and easily accessible databases are developed in the domains of ground water, surface water, rain fall and hydro-meteorology. 




*      Up gradation of existing Hydrological and Hydro meteorological stations. 

*      Establishment of Surface data centre in Bangalore.

*      Establishment of Water Quality Labs.

*      Data from 1901 has been computerized. 

*      Bathymetric survey equipments were procured for conducting sedimentation surveys of reservoirs. 


The Hydrology Project – I has thus helped the Department in creation of permanent assets for water resources department and helped in better collection of quality data, its computerization in SWDES software, its processing and for final storage. This Data is being disseminated to potential users for better water resources planning and management. 



Hydrology Project – II is a follow up action project of World Bank Aided Hydrology Project – I, wherein infrastructure for collection of data was established. The project became effective from 5th April 2006 and ended on 31.05.2014 


The overall project development objective of HP-II is to extend and promote the sustained and effective use of Hydrologic Information System by all potential users, concerned with water resources planning and management thereby contributing to improved productivity and cost-effectiveness of water related investments. 




*      The real time data transfer system has been established for transfer of rainfall data from Rain gauge stations through SMS Technology to the Central Server located at Bangalore. Automatic Weather Stations have been installed, and weather data is being received at an interval of every 30 minutes from these stations to the central server at Bangalore. 

RTDAS system for measurement of flows & Water level in rivers to assess inflow into major reservoirs of Karnataka has been established.



*      A website for Hydrology Project-II for Karnataka Surface Water has been developed and is hosting all the real time telemetric information. This web site also provides GIS platform for viewing of all water resources information.

*      Computers and peripherals have been upgraded in the State Data Centre, Divisional Data Processing centers and also in sub divisional data processing centres. 

*      Under this project training centre at KERS, K.R.Sagar has been upgraded. 

*      A Purpose Driven Study on study of river water samples at various sites in southern Karnataka has been completed.
