17.10 River and floodplain leakage, evaporation and errors

Supporting information

This line item refers to river and floodplain losses including evaporation and seepage that occur within the Perth region.

The volume of river and floodplain losses cannot be quantified accurately due to a lack of available data; however, these losses are considered to be relatively large and its omission may have a material impact on the water balance of the surface water store.
