摘要：
When the stream function is used to describe variable-density groundwater flow, it should be defined in terms of mass flux. The historic use of the stream function describes volume flux and implicitly invokes the Boussinesq assumption. A comparison of the flow equations for mass-based and volume-based stream functions indicates that this assumption can lead to significant errors in the calculated flow field, especially when flow parallels large density gradients.
