Three (ATelier Hydrologique Spatialisé (ATHYS), Hydrologic Modeling System (HEC-HMS), Soil Water Assessment Tool (SWAT)) with characteristics employed for continuous approach. The calibrated validated using observed daily rainfall streamflow data 4 years (2004–2008) 3 (2009–2011), respectively. multi-criteria model comparison (R², NSE, RSR, PBIAS) showed all three are capable reproducing flows. SWAT performed well over both periods (NSE = 0.76 calibration), improvement validation 0.84). A good agreement also HEC-HMS outputs, approximately stable NSE 0.77 0.78 calibration phases, ATHYS value 0.67 during calibration, decrease 0.06 towards period. other performance criteria confirmed these findings. Additionally, results suggest semi-distributed conceptual particularly suitable given their physical heterogeneity. Generally, integration may be resources assessment OLW.
