Map Viewing Service (WMS) of the dataset: Management pools in Charente-Maritime

As part of irrigation management, the Charente-Maritime department is divided into 17 management basins.
In these basins, measures to limit or suspend the collection of surface or groundwater shall apply.
An annual departmental framework decree lays down measures to limit or suspend water use in the department over the period from 1 April to 30 September.
For each basin thus defined, irrigation management rules are established, based on indicators triggering gradual measures.
There are 3 levels per indicator (piezometer or gauge station):
— alert threshold: 1st decrease in the volume of sampling allowed
— intermediate threshold: 2nd decrease in the volume of sampling allowed
— cut-off threshold: discontinuation of irrigation levies

作为灌溉管理工作的组成部分，滨海夏朗德省（Charente-Maritime）被划分为17个管理流域。
在上述流域内，需实施限制或暂停抽取地表水与地下水的相关措施。
一项年度省级框架法令规定了该省在每年4月1日至9月30日期间限制或暂停用水的相关措施。
针对上述划定的每个流域，均依据触发分级管控措施的监测指标制定了灌溉管理规则。
每个监测指标（测压管（piezometer）或水位监测站（gauge station））下设三级管控阈值：
—— 预警阈值（alert threshold）：首次缩减允许的灌溉取水量
—— 中级阈值（intermediate threshold）：第二次缩减允许的灌溉取水量
—— 断流阈值（cut-off threshold）：完全停止灌溉取水
