The Surface and Groundwater Archives (SAGA) Committee is pleased to announce a two-part webinar series designed to showcase the UK’s most important hydrological data archives, monitoring programmes, and forecasting tools. Together, these sessions will offer valuable insight into the data systems that underpin research, water resource management, and environmental decision‑making across the country.
Hydrological information plays a critical role in understanding how the UK’s rivers, aquifers, and catchments respond to long‑term pressures and extreme events. This webinar series will guide participants through the major national resources that support this work, from long-term archives to real‑time monitoring platforms and seasonal outlooks.
Webinar 1: The National River Flow Archive (NRFA) and National Groundwater Level Archive (NGLA)
Date: 17 March 2026
Time: 12:30 – 13:30
The National River Flow Archive (NRFA) and National Groundwater Level Archive (NGLA) are the cornerstone national repositories for long-term river flow and groundwater level data in the UK.
This webinar will:
• Introduce the scope and purpose of the NRFA and NGLA
• Explain how hydrological data are collected, curated, and quality assured
• Demonstrate how the data can be accessed and used for research, water resource planning, and environmental assessments
• Highlight recent developments and future plans aimed at improving accessibility and functionality of the archives

Webinar 2: UK Hydrological Monitoring and Outlook Tools
Date: 23 April 2026
Time: 12:30 – 13:30
The second webinar will focus on operational tools used for monitoring and forecasting hydrological conditions across the UK.
The session will introduce several key programmes and platforms:
UK National Hydrological Monitoring Programme (NHMP) and UK Hydrological Outlook
These programmes track hydrological conditions across the UK, placing current conditions and extreme events into historical context. They also produce seasonal outlooks that inform drought and flood risk assessments.
An interactive platform providing near real-time data to help users understand current hydrological conditions. The portal includes rainfall, river flow, groundwater levels, soil moisture data, and drought indicators across a range of spatial scales.
This tool supports the development and communication of seasonal outlooks, helping anticipate potential water resource pressures and hydrological extremes.

Who should attend ?
The webinar series is open to a wide audience, including UK Measuring Authority staff, researchers, water resource managers, policy makers, and anyone interested in hydrological data and forecasting.
Join us to deepen your understanding of the UK’s hydrological data landscape and learn how these archives and tools can support research, operational monitoring, and water management.
