# Check 13 - Check of Anaqsim leaky barrier line boundary

**Checks leaky barrier line boundary, interdomain boundary**

This compares two models with uniform recharge within a circular constant head boundary. The two models are identical, but one has a leaky barrier constructed with a leaky barrier line boundary and in the other, the leaky barrier is represented as a separate domain with finite width and the same equivalent resistance as the leaky barrier line boundary.

The plots below are plots of heads near the barrier in the two models and show nearly identical patterns.
