Hydrometeorology division (HMET) is mandated to carry out studies related to hydrometeorology, hydrology, water resources and applied statistics.In its early stages, the division made significant strides in the water resources sector by pioneering an innovative electrical analogy approach in offering solutions forprobable maximum flood estimation, seepage, subsurface flows and flood routing. With the advent of computer technology, the division seamlessly transitioned to incorporating advanced mathematical modeling techniques and developed some specific model tailored to water resource applications.

The division is also engaged in the research projects related to extreme value analysis of meteorological parameters, estimation of design flood discharge, flood frequency analysis, assessment of water availability, low-flow analysis, rating curve analysis. The division is involved in data analysis of various projects catering to hydrology as well as hydraulic modeling by adopting stochastic, probabilistic approaches and optimization techniques.

HMET has ventured into surface weather data collection by establishing Automatic Weather Station (AWS) and testing and calibration sensors at CWPRS campus under National Hydrology project and also has been disseminating the real time data. Along with this, the scientists of this division have been involved in training more than 1000 personnel in the field of AWS and sensor calibration through national and international workshops.

Broad areas of expertise

Collection, processing and analysis of hydro-meteorological data (i.e. rainfall, temperature, wind, evaporation, stream flow, etc.)
Review of design flood for minor and major dams using suitable rainfall-runoff models
Hydrodynamic modeling for prediction of high flood levels in river network, backwater studies and preparation of inundation maps
Evaluation of low-flows using statistical approach
Assessment of water availability
Estimation of sediment yield and sediment rate
Area drainage studies and determination of safe grade elevation
Optimization of rain gauge and stream gauge networks
Testing and calibration of meteorological sensors

Significant Contributions

The division has been hosting website www.hydromet.cwprs.co.in for real-time weather data visualisation, graphical data analysis, and historical data base management for seamless access from any part of the world.
The division has contributed in framing the terms of references for Real time stream flow forecasting (RTSFF) and reservoir operation system (ROS) for Indira Sagar project and Omkareshwar project in the Narmada Basin
Significant studies of this division include area drainage studies for BARC, NTPC, TPCIL, Tata Power, backwater studies for Padalse weir, Tapi river and Pranahita river, flood estimation studies of Ghaggar, Sutlej, Chenab, Poonch river, hydrological assessment for linear waterways for railway line project between Araria and Galgalia, Bihar.
