The present conditions of the Dittaino River were investigated by using tools addressing different components of the IDRAIM (stream hydro-morphological evaluation, analysis, and monitoring system) procedure. After the segmentation of the river, the Morphological Quality Index (MQI) and the Morphological Dynamic Index (MDI) were assessed to analyze its morphological quality and to classify the degree of channel dynamics related to progressive changes occurring in the relative long-term (i.e., 50–100 years), respectively. The results show that 45% and 22% of the analyzed reaches (mainly located in highest zones of the hydrographic network) were, respectively, of high and good quality. The MQI class decreased to good and then to moderate in the downstream direction, and two reaches were of poor class. The highest MDI classes were also mainly identified in the highest zones of the hydrographic network. Some limitations (i.e., the elevated number of indicators, as well as their simplification) and strengths (i.e., the easy applicability to a large number of reaches) were identified during the application of the MQI method to the Dittaino River.

意大利西西里岛东部 Dittaino 河的水文形态评估

通过使用解决 IDRAIM（河流水文形态评估、分析和监测系统）程序的不同组成部分的工具，对 Dittaino 河的现状进行了调查。河流分段后，评估形态质量指数（MQI）和形态动态指数（MDI）以分析其形态质量，并对与相对长期发生的渐进变化相关的河道动态程度进行分类（即, 50 –100 年），分别。结果表明，所分析的河段（主要位于水文网络的最高带）分别有 45% 和 22% 为优质和优质。下游 MQI 等级由好转为中等，2 段为差。最高的 MDI 类别也主要在水文网络的最高区域中确定。在将 MQI 方法应用于 Dittaino 河的过程中，确定了一些局限性（即指标数量增加及其简化）和优势（即易于适用于大量河段）。
