Dataset Direct Download Service (WFS): 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.河道（watercourse）的维护作业与运行活动会对周边自然环境造成影响，相关活动受法规规制。在河道内，仅符合常规维护定义的作业可无需事前备案即可开展。 超出常规维护范畴、需实施更大规模作业的河道内工程，需根据《水法》提交事前申报或授权申请文件。朗德省的河道测绘图已在国家行政服务部门官网发布，该测绘图为动态演进工具，每年4月完成更新。
