英文摘要	The Integrated Multi-Satellite Retrievals for Global Precipitation Measurement (GPM-IMERG) could be an alternative solution to the data lack problem. In this regard, this work examines the ability of this satellite-based rainfall products to simulate the flow in a Moroccan ungauged basin (Bourrous) by using the Soil Conservation Service-Curve Number (SCS-CN) model. We first applied this simulation in a nearby gauged basin (Ghdat) in order to validate it over a 17-year period. The datasets used in this study range from 2000 to 2017. The results, using ground-based rainfall, gave Nash-Sutcliffe criterion between 0.4 and 0.89 for almost all events. The mean relative bias on peak flow and volume are - 16.6% and 17.7%, respectively. We then assess at daily scale the GPM Level 3 IMERGD Early and Final dataset with a spatial resolution of 10 x 10 km. 3IMERGD-F outperforms 3IMERGD-E in terms of correlation and bias. These datasets are used to simulate flood events in the Ghdat basin. Using the 3IMERGD-E product, the comparison between simulated discharges and observations at the gauge station shows an underestimation of both the peak flow and the volume with a mean relative bias of - 33.42% and - 26.56%, respectively. With 3IMERGD-F, these biases become - 42.46% and - 33.74%. After the transposition to the ungauged Bourrous basin, the maximum peak flows estimated by 3IMERGD Early and Final are 168.4m(3)/s and 157.8m(3)/s, respectively. This study has thus shown the contribution of GPM Early and Final products in the estimation of flow rates in ungauged basins.
