“…Indeed, the performance of the model obtained in calibration as well as validation respects the conditions of Van Liew et al [49] and Moriasi et al [43]. Moreover, the performance remains very close to the work of Schuol et al [37] and [30].…”

“…The last adjustments of this phase concerned the calculation of potential SWAT is a complex model with many parameters that make it difficult to optimize. Indeed, it includes 629 parameters on which it is possible to adjust to have a good performance of model [5] [30]. In addition to these parameters, several uncertainties may arise during the SWAT model implementation.…”

The city of Bouaké, the second biggest city of Côte d'Ivoire, experienced a water shortage in 2018 that lasted four months due to the drying up of the Loka reservoir, which supplies two-thirds of the city. The challenge of the Loka reservoir is that it is located in an ungauged basin where very few hydrological studies have been carried out, despite the recurrent problems of access to drinking water. In the purpose to better understand the phenomena that caused this temporary drying of the dam, the methodology implemented was based on agro-hydrological modeling with SWAT using a regionalization technique of a nearby watershed. The model performance was assessed using three statistical indices (the Nash-Sutcliffe coefficient (NS), the coefficient of determination (R 2 ) and the percentage of bias (PBIAS)) and the visual appreciation of hydrographs for monthly series. The statistical indices appear satisfactory with a NS and R 2 ≥ 0.6 both for calibration and validation, and a PBIAS of −11.2 and −3.8 respectively for calibration and validation. The hydrological modeling of Loka basin has shown the impact of climate change already reported by some authors as well as anthropization. Thus, while the reservoir records a decrease in its water volume estimated at 384,604 m 3 each year, the water demand undergoes an increase of 122,033 m 3 per year.
