used in this model. The model was run in a continuous way at the daily timescale. The discharge at the outlet was available for ten years duration in which five years’s discharge data were randomly selected for the calibration purpose. The comparison observed and simulated discharge was based on Nash and Sutcliffe index. Data from other five years were used for validation. The parameter was calibrated using trial and error method. The model demonstrated a good calibration and validation result with the total Nash coefficients being 0.86 and 0.80, respectively. The maximum Nash coefficient in calibration was 0.92, while the minimum value was 0.68. In validation, the maximum and minimum of Nash coefficient were 0.92 and 0.68. Except for one value, the correlation coefficient between observed and simulated discharge was over 0.9 for both calibration and validation periods. The model can generally well reproduce the hydrograph except for some peaks and some baseflow periods. The relative error of the annul runoff volumes between observed and simulated runoff was about 23.1% in calibration period and 34.6% in validation period. The rainfall and runoff both had a great variation by year, while a corresponding relationship was observed between them. The eigenvalues of rainfall and runoff volume had a great inter-annual variation and the average value of annual rainfall was 1238 m and the variation coefficient was 20.2%. The average value of annual runoff depth was 0.52 and the variation coefficient of annual runoff depth reached to 47.0%. There is no big difference in the average of annual runoff volume and daily peak runoff volume between observation and simulation values, but the observed and simulated runoff volume both showed a great inter-annual variation in total runoff volume and daily peak runoff volume. ATHYS model has proven to be able to simulate runoff from Fengle catchment in a continuous way.
