National Hydrological Monitoring Programme - Hydrological Review of the Year

The National Hydrological Monitoring Programme (NHMP) published an annual review of hydrological events and hydrological conditions within each calendar year until 2010; thereafter the series was superseded by the quarterly UK Hydrological Bulletins. Based on analysis and interpretation of the data holdings of the National River Flow Archive and the National Groundwater Level Archive, the annual reviews placed the year in its hydrological context, focussing on rainfall, evaporation and soil moisture, river flows, and groundwater levels.

The Hydrological Review of the Year is available electronically in various formats:
