I want to generate a canal going from point A to B with a given slope.
The canal should be on the underlying DEM.
Is there any way to do this with the tools in ArcGIS 10 or do I have to do it manually?
I also have Qgis, Globalmapper and BricsCAD (with GeoTools) available if that helps in any way.
It's about an irrigation canal. We start at a dam with a given elevation. Now we go along the hill with a constant slope of let's say 0.1% downhill up to my endpoint (or end area). So eventually the endpoint is defined by the slope too. However I could figure out where the end point is and just linearly interpolate in between the two points then. The canal should be on the surface of the DEM.
We're talking about a canal on a hillside / in a valley so there is plenty of natural slope. The canal goes along the hillside from the start to the end of the valley. Basically following the contour lines but slightly sloping downwards in order to have some flow.
