| Zusammenfassung |
| A generic system dynamics watershed (GSDW) model is developed and applied to
five reconstructed watersheds located in the Athabasca mining basin, Alberta,
Canada, and one natural watershed (boreal forest) located in Saskatchewan,
Canada, to simulate various hydrological processes in reconstructed and
natural watersheds. This paper uses the root mean square error (RMSE), the
mean absolute relative error (MARE), and the correlation coefficient (R) as
the main performance indicators, in addition to the visual comparison. For
the South Bison Hills (SBH), South West Sand Storage (SWSS) and Old Aspen
(OA) simulated soil moisture, the RMSE values ranges between 2.5–4.8 mm,
and the MARE ranges from 7% to 18%, except for the D2-cover it was
26% for the validation year. The R statistics ranges from 0.3 to 0.77
during the validation period. The error between the measured and simulated
cumulative actual evapotranspiration (AET) flux for the SWSS, SBH, and the OA
sites were 2%, 5%, and 8%, respectively. The developed GSDW model
enables the investigation of the utility of different soil cover designs and
evaluation of their performance. The model is capable of capturing the
dynamics of water balance components, and may used to conduct short- and
long- term predictions under different climate scenarios. |
