The National Hydrology Project (NHP) is a Central Sector Scheme launched in 2016 by the Ministry of Jal Shakti. It aims to improve the extent, quality, and accessibility of water resources information and to strengthen the capacity of water resources management institutions in India. It is a follow-up to the Hydrology Project I and II, which were implemented between 1995 and 2014.
Objectives and Scope
The project focuses on creating a robust, real-time, and web-enabled water information system to support evidence-based decision-making for water resource management.
- Establishing a nationwide Hydrological Information System (HIS).
- Improving the institutional capacity of central and state implementing agencies.
- Developing tools and systems for water resource assessment, flood forecasting, and drought monitoring.
- Enhancing data reliability and availability for all stakeholders, including researchers and policy planners.
- Promoting the use of modern technology, such as satellite-based sensors and automated data acquisition systems (ADAS).
Key Components of NHP
The project is structured into four major components designed to modernize water data management.
- In-situ Monitoring System: Deployment of automated weather stations, piezometers for groundwater monitoring, and telemetry-based water level sensors in rivers to ensure real-time data collection.
- Data Acquisition and Management: Development of standardized data storage systems to archive historical and real-time hydrological and meteorological data.
- Water Resources Operation and Planning Systems: Creation of analytical tools and decision-support systems for reservoir operation, flood management, and irrigation scheduling.
- Institutional Capacity Building: Extensive training programs for technical staff and professional development for water sector experts to manage modern digital infrastructure.
Implementation and Funding
NHP is implemented through a decentralized framework involving central agencies and state-level departments.
| Feature | Details |
| Funding Pattern | 100% Centrally Funded (Central Sector Scheme). |
| World Bank Support | Supported by a World Bank loan under the Program-for-Results (PforR) mechanism. |
| Implementing Agencies | Central Water Commission (CWC), Central Ground Water Board (CGWB), and various State-level water departments. |
| Timeframe | Originally launched for 8 years; currently under extension to complete pending works. |
Major Technological Initiatives
NHP leverages advanced digital platforms to democratize water data access.
- India-WRIS (Water Resources Information System): A single-window information system for the country’s water resources, providing data on river basins, reservoirs, groundwater levels, and water quality.
- e-SWIS: An automated system for the collection and transmission of hydrological data from remote stations directly to the central server.
- Flood Early Warning Systems (FEWS): Development of state-specific flood forecasting models to reduce disaster risk and improve preparedness.
- Aquifer Mapping Tools: Integration of data from the National Aquifer Mapping and Management (NAQUIM) program to visualize groundwater trends across different geological formations.
Significance for Water Governance
- Data-Driven Policy: Provides the scientific basis for allocating water across sectors, including agriculture, industry, and domestic consumption.
- Climate Change Adaptation: Enables better monitoring of water cycle fluctuations, which is crucial for addressing the impacts of climate change on water security.
- Inter-State Cooperation: Standardized data formats facilitate better management of trans-boundary river issues between states.
- Transparency: By making data publicly available on the India-WRIS portal, the project enhances accountability in water governance.
Key Trivia and Facts
- NHP is recognized as the largest water sector project in India in terms of geographical and institutional reach.
- The project emphasizes the shift from “Manual Monitoring” to “Automated Real-time Monitoring” of hydrological parameters.
- The data generated under NHP is widely used for research purposes by universities, NGOs, and planning institutions.
- It supports the government’s broader “Digital India” initiative by transforming water resource data into a digital public asset.
- The project includes a specific focus on “River Basin Modeling,” which helps in simulating river flow under different climatic and usage scenarios.
