I have had a request to create a "point and click" drainage flow for a DEM. The user wants to be able to click on a pixel on a DEM, which then creates a polyline that shows the flow (path of least resistance) to the edge of the DEM. Currently, the existing models stop at a sink. The user wants it to continue pooling, and then continue until it reachest he edge of the map. Is (are) there any existing tool(s) that can do this?

Many thanks!
