Introduction

HBV light is a widely used model in hydrology that simulates daily discharge by incorporating daily rainfall, temperature, and potential evaporation as input parameters. This model is an adaptation of the original HBV (Hydrologiska Byråns Vattenbalansavdelning) model, which was developed in the 1970s by the Swedish Meteorological and Hydrological Institute. The HBV light model is a simplified version of the original HBV model, making it more accessible and easier to use for researchers and practitioners in the field of hydrology.

Key Features of HBV Light

Precipitation Simulation: HBV light simulates precipitation as either snow or rain, depending on the temperature threshold. This is a critical aspect of the model, as it allows for the accurate representation of the hydrological cycle in different regions.
Daily Discharge Simulation: The model uses daily rainfall, temperature, and potential evaporation as input parameters to simulate daily discharge. This allows for the accurate representation of the hydrological cycle at a daily time step.
Simplified Structure: HBV light has a simplified structure compared to the original HBV model, making it easier to use and understand for researchers and practitioners in the field of hydrology.

How HBV Light Works

HBV light works by using a combination of input parameters to simulate daily discharge. The model uses the following steps to simulate daily discharge:

Precipitation Simulation: The model simulates precipitation as either snow or rain, depending on the temperature threshold.
Potential Evaporation: The model calculates potential evaporation based on temperature and other input parameters.
Daily Discharge Simulation: The model uses daily rainfall, temperature, and potential evaporation as input parameters to simulate daily discharge.
