Urban water quality and hydrometric data for a range of urban developments in in the south of England. Water quality has been obtained from fortnightly-monthly sampling of river water using a Manta 2 sonde, and includes the parameters: ammonium, DO, pH, specific conductivity, temperature and turbidity. Rainfall was measured using a number of 2mm tipping bucket raingauges across the urban sites and through QC deriving a 15min time series of rainfall in millimetres for each site. Flow in cumecs was derived from in-situ stream channel measurements of velocity and depth using ultrasonic flow monitoring gauges.
