Several floods occurred in Erbil City in 2021 and 2022, which caused disaster in the city. 12 people died, thousands of houses and vehicles were destroyed, and numerous public projects such as electric stations and roads were damaged as well. Specifying reasons and providing suitable solutions are essential for minimizing damages. Thus, this resear...

The goal of this research was to determine the impact of a pooled and flat stepped spillway on energy losses. FLOW3D, which is a computational fluid dynamics (CFD) program, with mesh size of 0.015 mm was used for this purpose. First, the code was tested against an available experimental model data for both water flow depth and inception point posit...

The main features that attract hydraulic engineers for designing stepped spillways are their ability to lose a large portion of the flow energy and add or increase aeration to the flow naturally. Hence, smaller size stilling basin and no aeration device may require. This study aims to find the amount of energy dissipation rate and the location of i...

Using stepped chutes as a structure for controlling flood discharges is applicable for long time. Measuring the depth of flow over that structure is essential for designing of the side walls. The aim of this paper is to determine the free-surface that flows on spillway equipped with non-uniform step sizes. For that purpose, the two-dimensional soft...

The aims of this work were to characterization of industrial wastewaters such as dairy and steel manufacturing wastewaters, possible treatment processes, and reusing the treated wastewater for irrigation purpose was discussed. Fresh wastewater samples were collected from Yörüksüt Dairy Factory and Erbil Steel Company and analyzed for 21 water quali...
