The Auger Collaboration has recently published the energy spectrum of cosmicrays above 1 EeV, which exhibits interesting features. These spectrum featuresprovide an opportunity to investigate the propagation of ultra-high-energycosmic rays (UHECRs). In this study, we have developed a model thatincorporates the dip model for UHECRs in the extragalactic propagation, whileaccounting for the suppression due to diffusion and interactions within thegalaxy. Our model demonstrates excellent agreement with the energy spectrummeasured by Auger and supports a spectral index of 2 for the diffusioncoefficient in the galaxy starting from $5\times10^{18}$eV.
