I have a created a fully 2D rain-on-grid model. I wish to incorporate the baseflow of the rivers as an initial condition in the model. Are there any ways I can add this into the model?
you can insert a base flow hydrograph into the 2D flow area. Use the SA/2D Area BC Lines tool. Say you want a 200cfs base flow. Draw the BC line down the channel and in the flow editor manually enter the flow to assign to the BC line. Start your run time to start how ever long before your rainfall.
