Objectives and Model

Results and Analysis for 2 basins

The Flinders River (Glendower)

1. Actual evapotranspiration was estimated from potential one differently in wet and dry season .

2. Simulation using parameter sets determined for P1, P2, P3 show stable results .

3. That for P5 show unstable results, which probably influenced by a big flood in 2002 .

4. Low discharge is not reproduced well by any parameter sets.

1. NSE by the best parameter set is around 0.42. The model does not consider snow melt Flow regime is well reproduced from Aug. to Feb. and not from Mar. to Jul. Fraction of soil precipitation is low in P4, which impacts on the best result of flow regime and NSE in P4

Each component of the model o Has DEM data and flow direction to a neighboring element with the steepest

gradient.o Calculates water flow by kinematic wave model.o In mountainous area also consider subsurface flow in kinematic wave model by

discharge-storage relationship. This model has been successfully applied to many Japanese catchments in the temperate

climate with wet conditions. The objective of this research : How applicable this model is for different climate conditions ?
