Losses and gains time series (optional)

The following three losses / gains time series can be included:

·         Precipitation

·         Potential evaporation

·         Infiltration

To include losses/gains, enable ‘Include losses and gains’, click on the  button and click Browse... to select an existing time series or click Create a new file… to open the ‘Create a new file’ dialogue.

To create a file with non-uniform values, the file must first be created with a uniform value and then edited in time series editor.

This is done by clicking and selecting ‘Edit in time series editor’.

The losses/gains are included in the water balance calculations and the actual loss/gain in each time step (in terms of volume per time unit) will depend on the actual water level (and thereby surface area) in the reservoir at that time step.

If groundwater is defined in a downstream Catchment, infiltration from the Reservoir will be added to this groundwater. However, with the current imple­mentation the Reservoir has to be a Catchment node as well. Therefore to observe the infiltration from a Reservoir to groundwater, the Reservoir must have an immediate upstream and downstream Catchment (and the latter must have a groundwater model specified).
