The data consists of Bresle river and its tributaries water temperature since 1984 collected for the Environmental Research Observatory (ORE) on Diadromous Fish in Coastal rivers (DiaPFC). ORE DiaPFC is a research infrastructure focused on studying the influence of human-induced and environmental changes (mainly agriculture and climate). The River Bresle is 72 km long and has a mean slope of 0,26%. It drains a basin of 750 km2 and flows north-west through the Normandy-Picardy plateau ending into the English Channel at Le Tréport. It lies within a chalky geological zone and is fed from alluvial deposits. The water quality is generally fair, except for the occasional pollution by chronic agricultural run-offs. The mean flow is 7,3m3/s, with the highest mean flow in February (mean = 9,4 m3/s) and the lowest in September (mean = 6.4 m3/s).

Water temperature monitoring network on the Bresle river : The dataset consists of 2 files, one with the description of the monitored sectors and the other with the collected data (Sector, Date, Time, Temperature).
