  abstract = {{A} new precipitation dataset is provided since 2014 by the {G}lobal {P}recipitation {M}easurement ({GPM}) satellite constellation measurements combined in the {I}ntegrated {M}ulti-satellite {R}etrievals for {GPM} ({IMERG}) algorithm. {T}his recent {GPM}-{IMERG} dataset provides potentially useful precipitation data for regions with a low density of rain gauges. {T}he main objective of this study is to evaluate the accuracy of the near real-time product ({IMERG}-{E}) compared to observed rainfall and its suitability for hydrological modeling over a mountainous watershed in {M}orocco, the {G}hdat located upstream the city of {M}arrakech. {S}everal statistical indices have been computed and a hydrological model has been driven with {IMERG}-{E} rainfall to estimate its suitability to simulate floods during the period from 2011 to 2018. {T}he following results were obtained: (1) {C}ompared to the rain gauge data, satellite precipitation data overestimates rainfall amounts with a relative bias of +35.61% (2) {I}n terms of the precipitation detection capability, the {IMERG}-{E} performs better at reproducing the different precipitation statistics at the catchment scale, rather than at the pixel scale (3) {T}he flood events can be simulated with the hydrological model using both the observed and the {IMERG}-{E} satellite precipitation data with a {N}ash-{S}utcliffe efficiency coefficient of 0.58 and 0.71, respectively. {T}he results of this study indicate that the {GPM}-{IMERG}-{E} precipitation estimates can be used for flood modeling in semi-arid regions such as {M}orocco and provide a valuable alternative to ground-based precipitation measurements.},
