This dissertation aims to investigate the factors behind flash flooding in Erbil's central district, located in the Kurdistan Region of Iraq, and develop a methodology for assessing flood hazards in the city, despite limited data accessibility. In this thesis, each factor was investigated, including analyzing extreme precipitation events in the last two decades, including their spatial and temporal distribution of rainfall, intensity, and exceedance probability, and examines the impact of changes in Land Use and Land Cover (LULC) on the hydrological response of the Erbil basin. The hydrodynamic model's input data were generated using GIS-based modeling interface. HEC-RAS 2-D software package's suitability was ensured by evaluating two building representation techniques and two mathematical models (Diffusion-Wave Equations (DWE) and Shallow-Water Equations (SWE)) using the Toce River urban flood experimental model. The study utilized a two-dimensional hydrodynamic model (HEC-RAS 2-D) to assess the susceptibility, vulnerability, and socioeconomic impact of flooding in the study area. Using the model, flood hazard maps were created to show the extent of potential flooding in the study area during various rainfall events and return periods. Ultimately, the study concludes that without essential engineering measures, there is an increased probability of flooding in the center of Erbil.
