Identification of IOTA Watercourses (Installation and Construction) in the Bouches-du-Rhône department

The Environmental Code, L215-7-1, defines a water course by its natural bed, its source having a sufficient flow rate for most of the year, and its flow cannot be permanent given local hydrological and geololic conditions.

IOTAs are subject to declaration or authorisation under Article R214-1 et seq. of the Environmental Code according to their impact on aquatic environments. These impacts
are listed in several headings of a nomenclature.

《环境法典（Environmental Code）》第L215-7-1条将水道（water course）定义为拥有天然河床、全年多数时段径流量充足，但受当地水文与地质条件限制，其径流无法常年持续的水体通道。
各类IOTAs需根据其对水生环境的影响程度，依照《环境法典》第R214-1条及后续条款的规定进行申报或取得授权。相关影响已被列入某一分类命名体系的多个条目之中。
