The HBV (Hydrologiska Byråns Vattenbalansavdelning) hydrological model is decoupled to allow the user to build his/her own model. This version was developed by the author in IANIGLA-CONICET (Instituto Argentino de Nivologia, Glaciologia y Ciencias Ambientales - Consejo Nacional de Investigaciones Cientificas y Tecnicas) for hydroclimatic studies in the Andes. HBV.IANIGLA incorporates modules for precipitation and temperature interpolation, and also for clean and debris covered ice melt estimations.
