CGWB is
a national agency which operates through a regional offices network located in each state
which is coordinated by a national center and headquarters. By and large, all the
activities of the CGWB in the different states are conducted from their region offices. In
some states the regional offices operations are split between two regions and in some
supplemented by unit offices which run assigned activities over their jurisdiction.
CGWB is involved in routine
and specific operations as follows
1. Monitoring of water levels and quality
2.
Exploration & Construction of wells
3. Testing
aquifers for hydraulic parameters
4.
Computation of water balance
5. Resource
and development assessment
6. Water
quality studies
7. Special
projects and applied research
8.
Preparation of hydrogeological atlases
CGWB has been using GWDES (Ground Water Data Entry System)since 1999 for computerisation
of historical data. It was developed by DHV consultants and has MS Access Database at the
back end. Front end has been developed using Visual Basic. Recently data already entered
in GWDES has been converted into dedicated software GEMS.
Later a Hydrological Information System (HIS) at Agency, State and National level for
hydro-meteorological, surface water and ground water quantity and quality data was
established to integrate the countrywide data bases so that they can be disseminated to
the different users. (Figure shows Role of Hydrological Information System) Main
activities are as follows:
1. Assessing the needs of users
2.
Establishment of an observational network
3.
Management of historical data
4. Data
collection
5. Data
processing ,analysis and reporting
6. Data
exchange and reporting
7. Data
storage and dissemination
8.
Institutional and human resource development
In view of above, Regional Office Data Centre (RODC) was set up at Lucknow Regional office
using the state-of-the art technologies for the purpose of processing (Data Processing
Centre), storage (Data Storage Centre) and dissemination of data in a systematic manner.
For this purpose a dedicated software GEMS has been introduced that takes care of all the
requirements of Hydrological Information System.
Similar Data Processing and Storage Centres have been established in different
organizations at several places with a National Data Storage Centre at Faridabad.

(Ground Water Data Entry System)
Dedicated
software GROUND WATER ESTIMATION AND MANAGEMENT SYSTEM (GEMS) . Salient features are given
below:
Groundwater
Estimation and Management System(GEMS) has been developed by M/s Tata Infotech Ltd. for
CGWB.
This
software uses RDBMS (Oracle) as back end software and VC++ as front end. This is essential
for long-term sustainability of the data sets. Necessary features like data security,
protection from data correction and provision of controlled accessibility is part of the
system design. An efficient and user friendly query system helps in data retrieval. GEMS
includes GIS support to visualize and analyse spatial data. GEMS facilitates data entry,
processing, validation and dissemination of periodic or annual report. The data analysis
tool provided in GEMS has all the capabilities of spatial and temporal analysis of
hydrological data. Several methods of multivariate statistics, time-series and
geo-statistics have been provided. Various interpolation techniques including Kriging has
been included. Different modules like grain size analysis, fence diagram for stratigraphic
correlation, water quality data analysis, geophysical profiling/ sounding data handling
and analysis have also been provided. The data-capture module handles all sorts of spatial
data collected from landscape elements from toposheets, satellite data, and attribute data
such as: Well-site details, Geologic, geomorphologic descriptions, Assembly, Aquifer data,
Well-log lithology, geophysical logs, Well performance and hydraulics, Water quality,
Rainfall, Depth of water table and Ground water abstractions. The statistics module of the
application identifies inherent characteristics in the observed data, which is essential
for appropriate model identification and use. Spatio-temporal Data analysis tools have
been provided.
