RIVERS: Morphological conditions (IQM) (years 2010-2021)

<p>State assessment pursuant to Legislative Decree 152/2006. The Morphological Quality Index (IQM) is a parametric method that assesses whether human activities affect the natural evolution of a watercourse. The morphological status is assessed by considering geomorphological ‘functionality’, artificiality and morphological variations, which together contribute to the formation of the index. Quality, expressed in five classes, can vary from High to Bad, while when it contributes to the determination of the Ecological Status of river water bodies it is divided into only two classes: ‘High’ and ‘Not High’. Data by basin, body of water, class of belonging. Period 2010-2021.</p>

依据2006年第152号立法令开展的国家评估。形态质量指数（Morphological Quality Index，IQM）是一种用于评估人类活动是否影响河道自然演化的参数化方法。其通过考量地貌‘功能性’、人工化程度与形态变异度三大维度开展河道形态状态评估，三者共同构成该指数的计算基础。该质量等级原分为五级，覆盖从‘优（High）’至‘劣（Bad）’的区间；而当其用于判定河流水体的生态状态时，仅划分为‘优（High）’与‘非优（Not High）’两个等级。数据集按流域、水体及其所属等级进行分类，时间跨度为2010年至2021年。
