Abstract
The study of the hydrological analysis of the flood fans between the Tayyib and Jabab rivers is an important topic in order to reveal the volume of surface runoff in the region as the responsible factor and the basis for the development of the flood fans in the eastern regions of Maysan Governorate, whose area is (4516,145) km2 and confined between two latitude circles (55 32). (32 ° - 35 ° 32) north and longitudes (20 47 ° - 30 46 °), whose climate is characterized by high temperatures in summer and low in winter, the study relied on the analytical method and the quantitative method in the study of the hydrological analysis of fans, depending on the land cover and hydrological classifications of the fans. In the light of the interpretation provided by the topographical maps of the scale of 1/000/50 and 1/000/100 and the space visuals of the Landsat8 sensor for the study area for the year 2016, some standards were used, including what is known as the SCS_CN method, where the two sensing techniques were used. After the geographic information systems to obtain accurate information about the quality of the land cover in the region, which included many of them, for the purpose of extracting the value of (CN), which expresses the amount of permeability of surfaces to water, which Ranging from (0 - 100), the preconditioning soil moisture index (CN), the maximum potential for water retention coefficient after the start of runoff (S), the initial recovery index (la), the depth of runoff measurement criterion Q, and the estimation criterion Runoff volume (QV).
