Abstract
Background and Objective: The natural flow regime of the river is a very important factor in determining the functions of aquatic ecosystems and their surroundings. The aim of this study is to evaluate the hydrogeomorphological conditions of the Qorichai River in Ardabil Province using the MQI method.
Methodology: In order to achieve this goal, the Geomorphological Quality Index (MQI) method has been used. First, the river network is divided into homogeneous intervals (6 intervals). Then, related morphological indices such as bank stability, channel pattern, cross-section changes, sedimentation potential, and adaptation to the surrounding environment are calculated.
Results and findings: The results showed that the value of the geomorphological quality index in the studied intervals is between 0.77 and 0.27, among which the maximum coefficient is in interval 2 with a score of 0.77 in the good category, which indicates the greater dynamics of this interval compared to other intervals, and the minimum score is in interval 3 with a value of 0.27, which is in the very poor category. Therefore, it was concluded that the Qorichai River is in a poor condition from intervals 3 to 6 and does not have favorable conditions, but on the contrary, it has appropriate dynamics in intervals 1 and 2. Finally, it is suggested that practical measures be taken to protect the river in intervals with unfavorable quality.
