Dataset: High resolution hydrometric and sewer system monitoring of an urban catchment with complex flood risk

This dataset provides high density hydrometric and sewer system data collected under the Blue Heart project (Blue Heart, 2026) from 497 gauges across a 78 km2 urban catchment in the UK, including from rainfall gauges, fluvial water level gauges, groundwater monitoring boreholes, road gullies and in-sewer level sensors. This data is supplemented by metadata describing the sensor network, shape files providing detail on the catchment topography and layout of the fluvial and sewer systems, and additional air and water temperature data providing contextual environmental conditions.
