Hydrology Project – II is a follow up action project of World Bank Aided Hydrology Project – I, wherein infrastructure for collection of data was established.

Under Karnataka Surface water component of HP-II, majority of the works pertained to establishment of real time data acquisition system

ACHIEVEMENT:

Hosting of Website for Real time telemetric data.

The real time data transfer system has been established for transfer of Rainfall data from all 1010 raingauge stations through SMS

using GSM Technology to the Central Server located at Bangalore. The system is working satisfactorily for the last 3years.

The data is hosted on the website:www.karunadu.gov.in/karhp, data is also available in 117.218.106.122/cehp

The data can be viewed Basin wise, District Wise & taluk wise for any particular period.

A facility to download data in excel and pdf format is also made available in the website.

The total cost involved in setting up this data transfer system including the cost of mobile instruments, 2 central servers, software

etc. worked out to about Rs.30lakhs, whereas if telemetric raingauges had been established it would have been about 5 to 6 crores.

This low cost approach has been appreciated by the World Bank

16 Automatic Weather Stations have been established under HP-II.

Weather data from these stations is received every 30 minutes & data is transmitted via GSM/GPRS technology

The data is hosted on the website:www.karunadu.gov.in/karhp

Weather data can also be viewed in the following addresses: - 117.218.106.122/wrl – Data received from 11 stations - 117.218.106.188/weatherweb - Data received from 5 stations

Real Time Data Acquisition System for measurement of Levels & flows in major rivers of Karnataka has been established using :

* Radar sensor - 12 locations * Bubbler sensor - 1 location * Acoustic Doppler Current Profiler - 7 locations

The data is hosted on the website :117.218.106.122/rtdas

WORK UNDER PROGRESS : * Supply & Installation of Radar level sensors for

measurement of levels in 15 reservoirs is under progress. * Contract has been awarded and installation will be

completed shortly.

At one of the locations viz KRS dam site the radar level sensor has already been installed and data is being received.

A link to www.karunadu.gov.in/karhp web site is provided on GIS platform showing all water resources information.

The cost of softwares like arc view, arc GIS ,etc is about Rs 5 lakhs to Rs 12 lakhs.

Without using such special software, engineers can view the water resources information on this website.

The overall purpose of the project is to develop an open source Web based platform for the departmental personnel as well as to public to view with security privileges on the web portal.

The developed software on Web GIS system is hosted on Departmental Server 117.218.106.122:8087/webwris
