The Hydromet Division at New Delhi was established in 1971 for providing the necessary technical and operational support to various Central / State Govt. Organizations and other agencies in the field of Hydromet Design Flood Forecasting, Hydromet, Glaciological Studies.

            The main activities in this discipline are continuous built up of rainfall statistics, hydrometeorological studies for different river catchment with a view to estimate Standard Project Storm (SPS), probable Maximum precipitation (PMP), Time distribution of rainfall storm, Intensity-frequency Analysis of rainfall which is used by design engineers for construction of Dams, railways and road bridges, culverts etc. for different central and state organizations, Public Undertakings like National Thermal Power Corporation (NTPC), National Hydro-electric Power Corporation (NHPC) and Private Agency on their request.

            It also provides meteorological support for flood warning and flood control operation of the field units of Central Water Commission. Hydromet Division also participates regularly in glacier expedition to take meteorological observations to conduct snowmelt studies.

            The main unit are;

1) Rainfall Monitoring Unit

2) Design Storm Unit

3) Storm Analysis Unit

4) Glaciology Unit

5) Flood Met. Unit

6)  International Hydrological Programme

            In addition to these activities Division is implementing hydromet component of World Bank assisted Hydrology Project to improve Hydrological Information System in 13 participating states.

            Division is maintaining Central Hydromet Observatory (CHO) for the purpose of creating awareness amongst school children in the field of Hydro-meteorology.

            Division is also providing advices to National Disaster Management Authority(NDMA), National Water Development Agency(NWDA), Brahmaputra Board, Dam Safety Organizations of Central Water Commission, National Institute of Hydrology(NIH) etc. and is participating in inter-programmes as Asian Water Cycle Initiatives(AWCI), Monsoon Asian Hydro Atmospheric Scientific Research and Predictive Initiatives(MAHASRI), Asian Monsoon Year(AMY) organized by Tokyo University, US-AID Project of Ministry of Home Affairs as Nodal Agency etc.  Division also provides inputs to Commission of Hydrology and Working Group of Hydrology (RA-II) of World Meteorological Organization.  Division has brought out 13 hydromet monographs covering various aspects of Hydro-meteorology.  Hydromet Manual is one of them elaborating Standard Practices of Hydromet Analysis.  Division is actively engaged in Research and Development and produced research papers in the field.

            There is a Hydrology Section at Pune for rainfall registration and rainfall climatology established in 1946 and five small Hydromet Units at the five Regional Centres for organization and inspection of raingauge stations.
