Scientific challenge: 

At times of flood and drought, water managers need good estimates of current and future rainfall amounts and soil wetness. The Joint Centre for Hydro-Meteorological Research (JCHMR) brought together the research skills of the Met Office and the Centre for Ecology & Hydrology to work at the interface of weather and flow forecasting, especially to support flood warning and water resource management.

Project overview: 

The JCHMR brought Met Office and Centre for Ecology & Hydrology scientists together on one site at Wallingford in Oxfordshire.

Their research produced rainfall monitoring and forecasting models, and improved estimates of soil wetness.

They incorporated models of 

  • Catchment response to rain and snow,
  • Routing of flow down river channels,
  • Interaction of tide, surge and river flood in estuaries.

JCHMR researchers also looked to quantify forecast uncertainty as an aid to storm and flood warning.
