Quantitative measurements allow geomorphologists to compare genuinely and reasonably different landforms and compute morphological indices. This is useful in regionally identifying and describing, for example, tectonic activity. Rivers and drainage networks are one of the most important complications that are very sensitive to tectonic variations. The purpose of this study is to investigate the active tectonics of the Dalaki catchment area using geomorphic indices. In this baseline, six indicators of Bs drainage basin, Hyssometric integral Hi, T transverse T-axis symmetry, I-factor, D-drainage index, and SL-Lagardian length are used. In the study of the relationship between tectonics and morphometry in the studied basin, topographic, geological, topographic maps, geology, meteorology, hydrology, satellite imagery from trustees were prepared and after necessary processing for the research purposes Has been used. The results of the study show that the shape of the semi-arid and semi-symmetrical topographic symmetry is high, but the disturbances in the longitudinal profile of the river are high due to different lithology units and numerous fault structures. According to the survey on accurate data, the displacements that caused the fault are only visible on the Gurpi Formation. In this way, the aggregate data and ground evidence in the aquifer basin is semi-active in terms of the dynamics of the internal forces of the earth.
