Abstract The development of water resource management plans requires the use of streamflow modeling, especially in poorly monitored basins such as Oued Cherraa in eastern Morocco. Given the inherent challenges of direct monitoring in these areas, modeling serves as a crucial alternative for obtaining flow data. Comprehending the hydrological behavior of a basin is crucial for effectively addressing water-related challenges, such as floods, droughts, and the availability of water for hydropower, irrigation, and domestic needs. Additionally, it facilitates the creation of robust adaptation and preparedness strategies. This study modeled Oued Cherraa Basin using the Soil and Water Assessment Tool (SWAT) through the ArcSWAT interface, version 2012. The software, designated SWAT-CUP2012, which incorporates the SUFI- 2 algorithm for sensitivity analysis, calibration, and validation, was employed to refine the model. The model was calibrated over the 2014–2015 period and validated with 2016 data. The storage time constant for normal flow was most significantly influenced by the deep aquifer percolation (RCHRG_DP), the curve number (CN2), and the calibration coefficient. The outcomes of the calibration and validation processes yielded coefficient of determination (R2) values of 0.66 and 0.63, respectively. Nash–Sutcliffe efficiency (NSE) values of 0.58 and 0.60 were obtained. During the calibration period, the mean monthly flow recorded at the Tazarhine station was 2.077 m3/s. During the validation period, the velocity was 2.016 m3/s. A thorough methodology for calibration and validation was implemented to support the development of an improved model that accurately represents the hydrological processes within Oued Cherraa Basin. This data will be essential for designing effective water resource management and planning strategies in the region.
