The Hydrology Project (HP) has been central to efforts in India to improve the planning, development and management of its water resources, as well as flood forecasting and reservoir operations in real-time. The project ̶ having completed two phases (Phase I from 1996 to 2003 and Phase II from 2006 to 2014) ̶ has established the backbone of a comprehensive Hydrological Information System (HIS) in India, providing scientifically verified, uniformly accepted and widely accessed hydrological records covering all aspects of the hydrological cycle. Following on the success of the first two phases of the project, the Department of Economic Affairs (DEA), Ministry of Finance, Government of India, has requested World Bank assistance for a follow-on Project (HP-III).
Apart from improving and standardizing the country’s hydro-meteorological and geo-hydrological monitoring systems, HP-I and -II have been instrumental in promoting a paradigm shift from relatively isolated water resources development towards comprehensive planning, development and management of water resources in a river basin context. The Hydrology Project has also established a platform for water agencies in India to learn from each other, and encouraged them to modernize existing hydro-meteorological monitoring systems, move from manual to Real-Time Data Acquisition Systems (RTDAS), and develop tools for integrated water resources planning and management, to enhance the productivity and cost effectiveness of water-related investments. For the first time in the country, in three river basins, climate forecasts have been integrated with stream flow forecasts and reservoir operations, leading to significantly improved forecasting lead times which allow additional time to prepare for flood management and improve reservoir operations
HP-I covered nine states and six central agencies and HP-II was implemented in 13 states and eight central agencies, predominantly in Central and Southern India. HP-III will be implemented across India in all states and union territories
