Postdoc position on Hydrology

We are offering a 3-year postdoctoral position within the WATERWORKS2014 ERA-NET IMDROFLOOD project. IMDROFLOOD (“Improving Drought and Flood Early Warning, Forecasting and Mitigation using real-time hydro-climatic indicators”) is an international project cofounded by the European Commission and the member countries, and has parters from Spain, Portugal, South Africa, Romania, Moldova and Estonia. The position will […]

Unraveling the HRU water balance in SWAT (III)

End of the story (this continues the previous post). I read one year of data for one HRU from the output.hru in R (), and I applied the water balance equation described in the linked posts. This is basically the following: So, applying the previous equations I got: As it can be seen, the mass […]

Unraveling the HRU water balance in SWAT (II)

In a previous post I dug into the SWAT code for determining how was the water balance computed at the HRU level. This is done at the daily level in the code, but values in the output.hru file are usually given by months. The next question is how to compute a monthly water balance for […]

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 […]
