Title

Extreme river discharge and associated tide gauge co-occurrences from UK estuaries 1984-2013

Abstract

This dataset contains the dates and magnitudes of extreme river discharge and associated skew surge peaks for UK estuaries between 1984 and 2013. The lag time between the drivers is also provided. Thirty years of river discharge and sea level data for 126 estuaries around the UK were analysed. The river discharge and tide gauge data were used at a 15-minute temporal resolution. A peaks over threshold analysis was completed to identify peaks in the river discharge record which exceeded the 95th percentile. The largest skew surge associated with each extreme discharge event was identified, and saved if this value also exceeded the 95th percentile.

Lineage

Observed total water level (TWL, mODN) data were obtained from 27 class-A tide gauges, which form part of the UK National A-Class Tide Gauge Network, from the British Oceanographic Data Centre (BODC). Skew surge (S, m) was calculated from the detrended TWL. It is the difference between the maximum observed TWL and the maximum predicted TWL based on astronomical tidal constituents for every 12.42-h tidal cycle, and the time of maximum TWL was assigned to each S value. River discharge measurements were obtained from the Environmental Agency, Natural Resources Wales, and the Scottish Environment Protection Agency for 265 rivers across Britain. Discharge (Q) measurements were taken from the most downstream, non-tidal gauges on each river. River gauges were then selected based on two criteria; 1) they recorded 30 years of discharge from 01 January 1984 to 31 December 2013 (with no data gaps), and 2) they recorded a maximum discharge during this period that exceeded 50 m3 /s to identify rivers that could potentially contribute to flooding. This set 30-year period (1984−2013) was selected to ensure consistency between gauges and to maximise the number of gauges with full data included in the analysis. These criteria isolated 126 gauges, located in 126 distinct estuaries. A peaks over threshold analysis was then carried out on these data to identify co-occurrences between extreme river discharge and skew surge peaks. The dates and magnitudes of these co-occurrences were recorded in Microsoft Excel spreadsheets (one for each catchment), and these were converted to .csv files.
