Unraveling the HRU water balance in SWAT (I)

There is surprisingly very few information about how to compute the water balance at the hydrologic response unit (HRU) level with the Soil and Water Assessment Tool (SWAT) model. The SWAT theoretical manual does a good job in explaining the different concepts of the hydrological simulation performed in the model, and the SWAT input/output manual […]

Reading SWAT output.hru files in R

The output.hru file is one of the most important output files of the SWAT (Soil and Water Assessment Tool) simulation model. It contains daily or monthly (depending on how you configured your simulation) time series of about 70 variables that are computed within the HRUs (hydrologic response units) of your simulation. The HRUs are the […]
