Key Questions and comments during the morning session
• Following the presentations, a number participants were interested to know whether
groundwater was incorporated into the Water Accounting framework. It was
acknowledged that groundwater is one of the limitations of the current model. It is
not fully accounted for, as the model does not include lateral flow. However, efforts
are being made to address this by integrating SWAT-gflow framework in the model for
the future.
• Participants were also interested in comparing the performance of the model with
other studies conducted in the basin.
• The participants noted that the visualizations of the WA+ outputs were a significant
strength of the framework, they are great and serve as excellent tools for
communication.
• For the Incomati Basin, there is a need for a finer resolution simulation because
previous studies have shown that coarse resolution rainfall data does not capture the
peak rainfall accurately, leading to incorrect results compared to measurements taken
on the ground.
