From Rain into Water Peter Ewins Chief Executive Met Office

Met Office & water management Involved in Water management since the ‘40s Began operational forecasts of soil moisture and run-off on a monthly basis in the early ‘60s Now deliver assessment of ground water status every hour from our operational forecast system

MOSES Met Office Surface Exchange Scheme Soil moisture data derived from radar observations Advanced scientific representation of processes 5km spatial resolution Updated hourly Provides information on soil moisture status Being assessed by Environment Agency for use in producing flow prediction

MOSES Soil moisture deficit from MOSES Darcian flow of soil moisture Deep drainage Surface runoff Evaporation from bare soil, trees, grass, crops, wet canopies etc. Rain, Snow Radiation Roots extract water

Urban drainage modelling Risk based approach to urban drainage modelling

Global River Flow Change (%) Produced by Southampton University in collaboration with the Met Office’s Hadley Centre

Rainfall increase Projected heavy rainfall increase

UK rain radar coverage 1km coverage (50km range) 2km coverage (50km range) 5km coverage (250km range)

Storm Accumulations mm 1km resolution 5km resolution
