Abstract

This paper discusses the spatial and temporal rainfall characteristics in UAE. The country is divided into for climatic regions including the east coast, mountainous area, gravel plains, and the desert foreland. Available data, from 42 rain gauge stations, were used to develop relations among the four climatic regions and define the changes in the rainfall pattern during the last decade. The double mass curve technique was used to investigate the homogeneity of the data. Statistical moments of annual rainfall events were estimated for all stations. The 24-h annual maximum and the mean annual rainfall data for the four regions were analyzed for estimating the expected rainfall at different return periods using different methods. The rainfall data are presented using the intensity-duration-frequency curves which were derived from the point rainfall frequency analysis and the possible occurrence of flash floods in the different areas is discussed. It is concluded that the four regions have similar rainfall patterns but with significantly different magnitudes. The results of this study serve as a baseline data for all hydrological studies including design of dams, rehabilitation projects and mitigation of possible flood hazardous.
