The boundary elements where sources are injected are found by intersecting the SCHISM land boundary and NWM segments.
Ideally, an intersecting element (i.e., a source element or the parent element of the intersection point) should be identified when the intersection point is found.
However, it seems the source/sink element is found by first finding the intersection point, then searching the nearest element center. This is not equivalent to directly locating the intersecting element and could lead to slight misplacement of sources/sinks.
