Good day
My name is Essy, am currently working on a project, and I want to determine the current and future Water demand and supply for Tugela catchment in South Africa. However am experiencing problems, The catchment has more than 1 gauge station, and when I am trying to calibrate the stream flows I am experiencing problems because while adjusting the hydrological parameters for one gauge station, the other one statistics parameters are also changing. I need help with calibrating more than one gauge station.

Another problem is there are mines and bulk industries around the catchment but I cannot determine the annual activity level, annual activity rate and consumption because there is little to no data available. This problem is also experienced with livestock data

Another problem is, there is a transfer out within the catchment how do I put that into Weap.

How do I project future Water demand and supply, using Weap?

Thank you
