Analysis of Hydromorphometric and Hydrological Characteristics of Bazian River A Geomorphological Study

Abstract

Geomorphology, as a branch of natural geography, focuses on river basins as a whole natural unit of actions and shapes. It also studies the hydrological characteristics of rivers, such as determining the amount and velocity of river flow that affects the appearance of several geomorphological features. The Bazian River basin is located between the two lines of latitude (00':27":35°-00': 43":35°) and the two longitude lines (40': 57": 44° - 40': 18": 45°). East, which is located in the southwest of Sulaimani, covers an area of (357.87 km2) which is (2.5%) of the total area of Sulaimani province, its length is (37.58 km), and consists of (6) sub-watersheds. Geologically, the geological structures of the study area all date back to the third and fourth periods. In terms of climate, the area is located in the Mediterranean climate (17.3) Celsius, the area is diverse in terms of altitude, so the highest peak of the waterfall (1429 m), located in the mountain range of Hanjira, and the cantorial line (627 m) is considered the lowest point. The researcher also used the Berkeley equation to find the annual runoff income of the region, according to which the amount reaches (0.628 billion m3) and the accumulation time reaches (1.3 minutes/hour), the value of water response time reaches (1.16 minutes/hour), (1.16 minutes/hrs). Finally, the flood factor Bazyan River is (0.42).
