Map Viewing Service (WMS) of the dataset: Works hindering drainage (priority works) in Provence Alpes-Côte-d’Azur

A barrier to flow is a water-related structure that causes a change in surface water flow (in talwegs, minor and major stream beds and marine submersion areas). Only artificial barriers (from human activity) are taken into account.水流阻隔设施是指能够改变地表水径流（涉及深泓线（talwegs）、主次河床以及海洋淹没区）的涉水构筑物。本数据集仅统计源自人类活动的人工阻隔设施。
