When using the [[WMS:Time Computation Arcs|Node -> Flow Arcs]] command in the '''Feature Objects''' menu, only the portions of the stream that are part of the flow path from the selected point to the outlet get converted to time computation arcs. If you wish to compute the lag time between consecutive outlet points then you will need to convert the remaining stream portions to time computation arcs. This is the purpose of the '''Streams -> Flow Arcs''' command. Not all streams are converted when using this command, only those stream segments that connect outlets. This command works for either TIN or DEM feature object stream segments.

When using the Node → Flow Arcs command in the Feature Objects menu, only the portions of the stream that are part of the flow path from the selected point to the outlet get converted to time computation arcs. If you wish to compute the lag time between consecutive outlet points then you will need to convert the remaining stream portions to time computation arcs. This is the purpose of the Streams → Flow Arcs command. Not all streams are converted when using this command, only those stream segments that connect outlets. This command works for either TIN or DEM feature object stream segments.
