| Zusammenfassung |
| This paper presents a package of modified temperature-index-based snow
water equivalent models as part of the hydrological modeling system
NewAge-JGrass. Three temperature-based snow models are integrated into the
NewAge-JGrass modeling system and use many of its components such as those
for radiation balance (short wave radiation balance, SWRB), kriging (KRIGING), automatic calibration
algorithms (particle swarm optimization) and tests of goodness of fit
(NewAge-V), to build suitable modeling solutions (MS). Similarly to all the
NewAge-JGrass components, the models can be executed both in raster and in
vector mode. The simulation time step can be daily, hourly or sub-hourly,
depending on user needs and availability of input data. The MS are applied on
the Cache la Poudre River basin (CO, USA) using three test applications.
First, daily snow water equivalent is simulated for three different
measurement stations for two snow model formulations. Second, hourly snow
water equivalent is simulated using all the three different snow model
formulae. Finally, a raster mode application is performed to compute snow
water equivalent maps for the whole Cache la Poudre Basin. |
