The Morphological Quality Index (MQI) and the Morphological Quality Index for monitoring (MQIm) have been applied to eight case studies across Europe with the objective of analyzing the hydromorphological response to various restoration measures and of comparing the results of the MQI and MQIm as a morphological assessment applied at the reach scale, with a conventional site scale physical-habitat assessment method. For each restored reach, the two indices were applied to the pre-restoration and post-restoration conditions. The restored reach was also compared to an adjacent, degraded reach. Results show that in all cases the restoration measures improved the morphological quality of the reach, but that the degree of improvement depends on many factors, including the initial morphological conditions, the length of the restored portion in relation to the reach length, and on the type of intervention. The comparison with a conventional site scale physical-habitat assessment method shows that the MQI and MQIm are best suited for the evaluation of restoration effects on river hydromorphology at the geomorphologically-relevant scale of the river reach.
形态质量指数（MQI）和监测用形态质量指数（MQIm）已应用于欧洲的八项案例研究，旨在分析各种恢复措施对水生生境形态的响应，并比较 MQI 和 MQIm 作为在河段尺度上进行形态评估的结果，与传统的基于地点尺度的物理生境评估方法。对于每个恢复河段，这两个指数都应用于恢复前和恢复后的条件。恢复后的河段还与相邻的退化河段进行了比较。结果表明，在所有情况下，恢复措施都改善了河段的形态质量，但改善的程度取决于许多因素，包括初始形态条件、恢复部分与河段长度的关系，以及干预的类型。与传统的基于地点尺度的物理生境评估方法的比较表明，MQI 和 MQIm 最适合于评估恢复措施对河流水生生境形态的影响，这是与河流河段的地貌相关尺度。
