Map Viewing Service (WMS) of the dataset: Identification of rivers in the Department of Landes

Maintenance works and operations on a watercourse have an impact on the surrounding nature and are regulated by regulations. In a watercourse, only work that meets the definition of regular maintenance can be carried out without a prior record.
In-water works requiring greater intervention than regular maintenance must be submitted a prior declaration or authorisation file under the Water Act. Watercourse mapping in the Landes Department is published on the State Services website. It is an evolutionary tool updated annually, in April.

水道（watercourse）的维护工程与运维作业会对周边自然生态造成影响，且受相关法规规制。
在水道范围内，仅符合常规维护定义的作业可免于事前备案。
相较于常规维护、干预程度更高的水下工程，需依据《水法（Water Act）》提交事前申报或授权文件。
朗德省（Landes Department）的水道测绘图将发布于国家服务网站，该工具为动态迭代更新平台，每年4月完成更新。
