EXTREME RAINFALLS AS A CAUSE OF URBAN FLASH FLOODS; A CASE STUDY OF THE ERBIL-KURDISTAN REGION OF IRAQ
Abstract
Aim of the study The current paper aims to give a detailed evaluation and analysis of some extreme rainfall events that happened in the last decade in terms of spatial and temporal rainfall distribution, intensity rate, and exceedance probability. Moreover, it examines the effects of each analysed aspect on the resulting flash floods in the studied area. Material and methods In their glossary of meteorology, American Meteorology Society (AMS) subdivided rainfall intensity types into four groups (light, moderate, heavy, and violent). Also, for estimating the exceedance probability, lognormal distribution was applied as a statistical model of the precipitation probability distribution function. Results and conclusions Out of six episodes, five of the analysed events were classified as heavy rainfall. However, the duration of those heavy rainfall events was not more than two hours. Four events of maximum daily rainfall (for a 39-year dataset) were rated at 1–10% of exceedance probability. To conclude, the current study can be an initial step in modelling hydrological events in the studied area, and in the process of transforming precipitation into the outflows of urban basins in the future.
