Water temperature on the Bresle river and its tributaries (Seine-Maritime and Somme county - France)

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).

本数据集包含1984年起，由沿海河流洄游鱼类环境研究观测站（Environmental Research Observatory on Diadromous Fish in Coastal Rivers，缩写ORE DiaPFC）采集的布勒河（Bresle River）及其支流的水温监测数据。该观测站是专注于人为活动与环境变化（主要为农业活动与气候变化）影响研究的科研基础设施。布勒河全长72千米，平均坡度0.26%，流域面积750平方千米，自西北向流经诺曼底-皮卡第高原，最终于勒特雷波尔（Le Tréport）注入英吉利海峡。该流域地处白垩地质带，水源补给源于冲积沉积物。河流水质整体状况尚可，仅偶尔会受到长期农业径流造成的污染。该河平均径流量为7.3 m³/s，2月平均径流量最高（9.4 m³/s），9月平均径流量最低（6.4 m³/s）。
