Application of Regional Hydrological Modelling:

Results for Present Climate under RICCAR

Ghasem Alavi & SMHI Staff Swedish Meteorological and Hydrological Institute

HYPE model: Hydrological Predictions for the Environment:

Developed 2005 to 2008 at SMHI, based on the widely applied HBV concept

Aimed at catchment-scale water and nutrient modeling

Process-based (water and nutrients)

Components: soils, rivers, lakes and reservoirs

Daily time-step

Management: dam regulation, irrigation, and fertilization
