Dataset Direct Download Service (WFS): Generators of easements PM4 (water retention areas) in Corrèze

PM4_GENERATEUR_SUP_S The PM4 easements relate to water retention areas, stream mobility zones, and so-called ‘water management strategy’ areas and relate to the following: — the creation of temporary retention areas for floodwater or runoff, by means of improvements to artificially increase their storage capacity of such waters, in order to reduce floods or runoff in downstream areas; — the creation or restoration of the mobility areas of the minor bed of a watercourse upstream of urbanised areas in areas known as ‘mobility areas of a watercourse’, in order to preserve or restore its essential hydrological and geomorphological characteristics; — preservation or restoration of “strategic areas for water management” defined by the plan for the sustainable management and management of water resources and aquatic environments of a water management and management scheme (SAGE). This resource describes the PM4 easement generators, namely: — areas of flooding or runoff downstream of temporary flood or runoff retention areas; — the mobility areas of the minor bed of a watercourse; — wetlands identified as strategic areas for water management in a SAGEPM4_GENERATEUR_SUP_S PM4地役权（PM4 easement）涉及蓄滞洪区、河道流动区域以及所谓的“水管理战略区域”，具体涵盖以下内容： — 通过人工改造提升蓄水容量，构建洪水或径流临时蓄滞区，以降低下游区域的洪水与径流风险； — 创建或修复位于城市化区域上游、被划定为“河道流动区域”的河道浅滩流动区域，以保留或恢复其核心水文与地貌特征； — 对由水管理方案（SAGE）中的水资源与水生环境可持续管理计划所界定的“水管理战略区域”进行保护或修复。 本资源所述为PM4地役权的涵盖范畴，具体包括： — 临时蓄滞洪区下游的洪水或径流淹没区域； — 河道浅滩的流动区域； — 被SAGE界定为水管理战略区域的湿地。
