HydPy-H (HBV)

HydPy implements a very close emulation of the central routines of the famous HBV96 model, introduced by Lindström et al. (1997). As discussed by Tyralla (2013), the results of version 1 application models of HydPy-H and the IHMS-HBV96 implementation of the Swedish Meteorological and Hydrological Institute agree very well for the tested river basins. This documentation focusses on technical aspects of HydPy-H and tries to be as precise as possible regarding the implementation of the process equations. The background of the scientifical development of the HBV96 model is more thoroughly covered in Lindström et al. (1997).

HydPy-H is divided into two base models, which can be used to compile different application models:

• hland (HydPy-H-Land)
• hbranch (HydPy-H-Branch)

So far the following application models are compiled:

• hland_v1 (HBV96)
• hland_v2 (HBV96-SC)
• hland_v3 (HBV96-SC/PREVAH)
• hland_v4 (HBV96-SC/COSERO)
• hbranch_v1 (HBV96)

All these application models are stand-alone models, which can be combined freely with all other models implemented in HydPy.
