Geomorphic indicators are considered to be prominent tools to learn about the interaction of tectonic processes and geomorphic shapes the earth’s surface. Worth mentioning, this evaluation uses a number of indicators that provide a very thorough concept of the influence of tectonic activity on watersheds. The research area consists of(10) watersheds in Bngird district of Sulaymaniyah province, in addition to that, the aim to determine the efficiency of tectonic activities on the watersheds in Bngird sub-district. The watersheds flow in to the Little Zab River in the northeast, as well as Dukan Lake in the west, by practicing geomorphic indicators, such as (AF) to determine dissimilarity and (SL) to select the length and slopes grades and(SMF) to show the fold of mountain fronts and (VF) to determine the rate of width of the base of valleys to their heights and (T) to know topographic similarity and (HI) Hypsometric curves for measuring the stages of the watersheds, indicate(IRAT)the sum of all the previous indicator results gives a comprehensive view of the tectonic activity for all watersheds in the study area that is their total numbers are (10) watersheds. In the end, the results of this study show that the rate of tectonic activity of all watersheds in the study area is at a moderate level, generality the entire study area has been subjected to tectonic activity. In this research, the used the quantitative analysis method and relied on numerical high-resolution satellite images (DEM 12.5) and images (LANDSAT-8) by using (ArcGIS 10.8).
