+
Modelling tools differ in the hydrological processes, or water balance elements (fluxes and storages), that they calculate individually, save, and allow users to export for further analyses. The table below covers what each software tool outputs, meaning what can be saved as a timeseries of flow rates, fluxes, or storage volumes or depths, and for what ''spatial scale'' or modelled units these can be output (e.g. output for each grid cell, HRU, subcatchment, or catchment total). Output file formats are covered [[Modelling tool user interfaces#Formats of input and output data|here]].
 
+
</br></br>
 +
The spatial scales at which the software can output values gives an indication of how much external calculation work a user may need to do in order to find out about a flux or store of particular interest. For example, we often wish to know the ET water use of a particular vegetation type, likely to compare with another type. ACRU and SWAT will output AET components for individual HRUs, however if there are multiple HRUs of the same land cover type within the model type, these tools will not compile an area-weighted average for the cover type across the whole modelled area. The user would need to do that manually outside the tool using the individual HRU outputs. MIKE-SHE can do this compilation within the software as the user can specify a polygon that covers the full area of a cover class and the tool will compile fluxes for that polygon.   
 +
</br></br>
 +
'''Note:''' The table differentiates between the case in which a ''tool does not output'' its calculation of a certain flux or storage (Output = "no") and the case in which the ''tool does not explicitly model'' the listed process ("not modelled"), meaning it's not part of the model's calculations. In the case when a tool ''does model'' a process, but ''does not output'' the results of this calculation, the user could potentially consult the tools' user guide and attempt to calculate the process themselves using the algorithm that is applied in the software and other components that can be output. In cases where a calculation would be relatively simple, and based only on other outputs covered in the table, the calculation approach has been given in the table.</br>
 +
For cases where the tool does output a flux but uses a different name for it that has been used in the table row heading, this has been noted in brackets below. For more terminology comparison across tools, see further coverage [[Terminology#Hydrological process and parameter terms across tools|here]]. </br>
 +
Some of the fluxes listed in the table are net totals of component fluxes which are also listed in the table (e.g. total AET or total evaporation & transpiration = canopy interception evaporation + AET from soil + AET from GW + evaporation off water bodies, where applicable). Some tools model and output each separately and may or may not output each individually. Some provide outputs of the total and the components, some just the components and the user would need to sum them if the total was of interest. Some calculate a total of some or all in a single step and output the total.

Modelling tools differ in the hydrological processes, or water balance elements (fluxes and storages), that they calculate individually, save, and allow users to export for further analyses. The table below covers what each software tool outputs, meaning what can be saved as a timeseries of flow rates, fluxes, or storage volumes or depths, and for what spatial scale or modelled units these can be output (e.g. output for each grid cell, HRU, subcatchment, or catchment total). Output file formats are covered here.

The spatial scales at which the software can output values gives an indication of how much external calculation work a user may need to do in order to find out about a flux or store of particular interest. For example, we often wish to know the ET water use of a particular vegetation type, likely to compare with another type. ACRU and SWAT will output AET components for individual HRUs, however if there are multiple HRUs of the same land cover type within the model type, these tools will not compile an area-weighted average for the cover type across the whole modelled area. The user would need to do that manually outside the tool using the individual HRU outputs. MIKE-SHE can do this compilation within the software as the user can specify a polygon that covers the full area of a cover class and the tool will compile fluxes for that polygon.

Note: The table differentiates between the case in which a tool does not output its calculation of a certain flux or storage (Output = "no") and the case in which the tool does not explicitly model the listed process ("not modelled"), meaning it's not part of the model's calculations. In the case when a tool does model a process, but does not output the results of this calculation, the user could potentially consult the tools' user guide and attempt to calculate the process themselves using the algorithm that is applied in the software and other components that can be output. In cases where a calculation would be relatively simple, and based only on other outputs covered in the table, the calculation approach has been given in the table.
For cases where the tool does output a flux but uses a different name for it that has been used in the table row heading, this has been noted in brackets below. For more terminology comparison across tools, see further coverage here.
Some of the fluxes listed in the table are net totals of component fluxes which are also listed in the table (e.g. total AET or total evaporation & transpiration = canopy interception evaporation + AET from soil + AET from GW + evaporation off water bodies, where applicable). Some tools model and output each separately and may or may not output each individually. Some provide outputs of the total and the components, some just the components and the user would need to sum them if the total was of interest. Some calculate a total of some or all in a single step and output the total.
