Periodical Monitoring of Ground Water levels –
- Ground water is a dynamic resource, which replenishes periodically by with precipitation every year. To have a watch on the behaviour of ground water, there is a system of periodical monitoring of ground water level in four scheduled periods (Jan./Apr./Aug./Nov.) In a year through 2000 odd Permanent Hydrograph Stations (PHS) scattered over different parts of the State. On the basis of such data, the periodical reports were compiled and circulated to aware the developmental agencies and masses as a whole. This data is very helpful in predicting the ground water situation in different regions as well as long term prospective planning.
-
During the financial year 2011-2012 both the wing of Engineering and Geological completed all the works in scheduled periods.
District wise distribution of Permanent Hydrograph Station is given below:- Sl No District Number of Permanent Hydrograph Station 1 Pascim Medinipur 216 2 Purba Medinipur 232 3 Bankura 238 4 Purulia 133 5 Howrah 87 6 Birbhum 82 7 Burdwan 203 8 Kolkata 65 9 Hoogli 129 10 North 24 Parganas 125 11 South 24 Parganas 79 12 Nadia 191 13 Murshidabad 114 14 Malda 43 15 Uttar And Dakshin Dinajpur 42+36 16 Darjeeling 49 17 Jalpaiguri 70 18 Coochbehar 54 Total 2188
NOTE:
A comprehensive study can be made if a record of fluctuations of ground water
levels is obtained along with the records of rainfall. For such purpose, an instrument named “Automatic Water Level
Recorder” have already been installed at 6 districts at
- Burdwan Agri-Irrigation Bunglow Campus, Burdwan,
- Chinsurah Agri-Mechanical Bunglow Campus, Hooghly,
- Suri Agri-Irrigation Bunglow Campus, Birbhum,
- Domjur Block Office Campus, Howrah,
- Administrative Building of W.R.I.D&D, Jalpaiguri
- Administrative Building of W.R.I.D&D, Coochbehar.
This instrument gives a continuous record of fluctuations of the groundwater levels
