If the Water Quality flag is turned off for a watershed, the Water Quality Alternative UI will be hidden from the user. However, any information that the user has already entered for the water quality simulation will not be deleted even if water quality is subsequently turned off for the watershed or the alternative.
To perform water quality modeling in a watershed, ensure that all necessary water quality information is defined in the Water Quality module. Then, to proceed with the simulation, open the ResSim Alternative Editor through the Alternative → Edit menu (Open Alternative Editor).
