Summary and Conclusions

• Modeling system centered on TOPMODEL for representation of spatially distributed water balance based upon topography and GIS data (vegetation and soils).
• Capability to automatically set up and run at different model element scales.
• Encouraged by small scale calibration, though physical interpretation of calibrated parameters is problematic.
• Large scale water balance problem due to difficulty relating precipitation to topography had to be resolved using rather empirical adjustment method.
• Results provide hourly simulations of streamflow over the entire watershed.
