Frequently Asked Questions (FAQ)

What is Hydrological Information System (HIS) ?

HIS is a scientific process of capturing reliable data on the quantity and quality of hydro-meteorological, hydrological and hydro-geological systems on space and time. It basically measures rainfall, climate, river flows, ground water levels and water quality. The system covers everything from the initial measurements through data collation, processing, checking and storage through to dissemination to information users. Hydrological information in India is primarily provided by various agencies of the central and state governments.

Who are the end users of HIS?

Development Planners, Administrators, WRM Departments, Public Works Departments, Rural and Urban Water Supply Departments, Farmers, Public Representatives, NGOs/CSOs, Scientists, Researchers, Academicians, Students, Water Resource Management Consultants, Mining Companies, Industries, Power Generation Companies, Navigation Companies, Developers, Water Utilities, Water Theme Parks, Large Plantations, Horticulture Companies, Agriculture Cooperatives and all who directly or indirectly uses water are the End User of HIS.

Characteristics of new HIS

  • It is collected and analyzed using standardized equipment and procedures for data collection,
  • It employs (computerized) processed and validated databases for efficient dissemination, and
  • It is demand driven, i.e., output is tuned to user needs,
  • It provides for proper institutional support to ensure sustainability.

One of the key objectives of Hydrology Project-II is to standardize the data processing and storing system to provide easy access to the well organized and reliable data. It is very essential to use software which is customized to facilitate data punching operations, carrying out necessary checks while entering the data and maintaining the punched data meticulously in well organized databases. The requirements for such a data entry scheme for surface water data is fulfilled by this "Surface Water Data Entry System" called SWDES.
SWDES is dedicated software developed for use in personal computers in WINDOWS 95/ 98/ NT/ 2000 environment. The software has been developed using Visual Basic for Access with a Microsoft Access 97 back-end database. The software is, in general, very user friendly as it provides sufficient information and comfort while working. It has been specifically designed to fulfill the requirements of the surface water data entry needs. To properly use this software, the user needs to be familiar only with the Windows environment on a personal computer.

HYMOS optimally serves the needs of Surface water authorities - like hydro-meteorological services and water boards - responsible for monitoring network operation and database management. The wide variety of data processing and analysis features make HYMOS very suitable for typical project application in water-related studies, research and consultancy. These projects often require processing of large amounts of data in a limited time frame.
HYMOS is used world-wide in over 30 countries by water authorities, consultants, research institutes and universities. Through continuous feedback from users all over the world during the more than 20 years of its existence, HYMOS developed into a flexible and multi-functional hydrological information system.

What are the fields of application of HYMOS? TOP
  • surface and ground water hydrology
  • meteorology

What is Groundwater Estimation and Management System (GEMS)? TOP

Groundwater Estimation and Management System (GEMS) is a comprehensive solution for groundwater management, developed for the Central Ground Water Board (CGWB), Ministry of Water Resources, and Government of India under the Hydrology Project. GEMS provides tools to effectively compile, visualize, and analyze hydro-geologic and allied attributes of groundwater resources. Its integration with business software of multiple domains makes it a thorough and complete solution for exploration, planning, development and management of groundwater resources.
GEMS is built using MapInfo Professional (GIS), MapInfo Vertical Mapper (spatial interpolation and contouring), SPSS (statistical analysis) and R2V (raster-vector data conversion). MapInfo's solutions offer a unique combination of software allowing customers to map, visualize, profile, compare and act upon information.
GEMS covers geophysical investigations, water quality studies, borehole/well logs, time series analysis of water level, rainfall and other meteorological data, as well as spatial analysis in targeting and estimating groundwater resources. GEMS, with specific alterations, can reasonably meet the needs of the above domains. Available GIS based spatial analysis tools, provided by MapInfo in GEMS such as interpolation, contouring, predictive modeling and forecasting can be effectively used to analyze data of the above domains.

What is WISDOM?

To store the data centrally from all the participating agencies, Central Water Commission (CWC) has developed software for all surface and ground water participating agencies for data storage & dissemination as a centralized procurement under the Hydrology Project. The software has been named as Water Information System and Data Online Management (WISDOM). WISDOM has been installed at all the Data Storage Centers. The software has been developed on MS SQL platform and is of generic nature so as to store the data exported by different data entry and processing software like SWDES, HYMOS, GWDES, GEMS, IMD formats etc. As a matter of fact data from any new software can also be mapped with the WISDOM software without much difficulty. Focus has been to have common software for storage running across all the agencies working in the domain of collection of hydrological and hydro-meteorological data.

What are the main features of WISDOM software? TOP

Main features of the WISDOM software are:

  • Store and administer field and authenticated hydrological data
  • Function as a Library for Hydrological Data
  • Ensure compatible database configuration and protocols by agencies
  • Maintain a professional data security system
  • Generate and maintain Metadata and Catalogue
  • Make authenticated data available for Hydrological Data Users (HDU)
  • Preparation of MIS reports
  • Archival of historical data

What is Hydrology Data User Group (HDUG)?

The Hydrology Project is investing resources in the setting up of a reliable, validated and processed Hydrological Information System (HIS) for the benefit of interested users. An effort has to be made to ensure that the HIS output responds to the needs of the users and it continues to be 'demand driven'. It is in this context that each of the states and central agencies under HP-II involved in assembling the HIS have constituted separate Hydrological Data Users Group (HDUG), representing current and potential users of data. Thus HDUG is a group of individual and or institutional users who are or can be a potential user of Hydrological data.

What is the purpose of HDUG?

The overall purpose of setting up state and central level Hydrology Data Users Groups (HDUGs) is:

  • To provide a common platform for discussions between hydrology data users and data providers.
  • To create awareness amongst users about HIS data and educate them on the potentials and limitations of HIS.
  • To understand, analyze and update information on the changing needs of data users from a macro level perspective.
  • To review and recommend additions/deletions in the data collection networks and related HIS, if appropriate.
What are the eligibility criteria of becoming member of HDUG? TOP

HDUG is a state or national level representative group of current and potential 'large scale' and 'repeat users' of HIS data who have a stake in water resource utilization, assessment and management. The membership of this group is determined by the respective states or central agencies. The recommended membership of HDUG in each state or central agency is approximately 25 to 30 members. The members are drawn from three distinct categories of users namely: Government, Voluntary and Private.

What is the role of HDUG?

The HDUG body will be vested with two broad roles:

  • Advisory role; and
  • Demand supply linkage role
