How do I fix an edge-of-field bioreactors tool error? I believe “sheds_poly” corresponds to the polygon feature class of the drainage areas of each bioreactor site, which is an internal calculation of the tool. I tried saving the output Bioreactor shapefile to a new file geodatabase (.gdb) to see if perhaps there was not enough memory in the current file geodatabase, but the same error resulted. Only 1 field boundary was identified in this particular watershed as requiring tile drainage. Any thoughts?

The ‘sheds_poly’ must be at least 10 acres. If there are no polygons left after removing the small ones in the feature class, the repair_Geometry method will likely fail. We should put a test in theRead More…

What is the unit of measurement for the NRCSWidth in the Riparian Function Tool Outputs?

The NRCS Width is in meters. It’s determined by converting the local runoff from hectares to sq meters, multiplying by 0.02 (2% of the contributing area to the buffer as recommended by NRCS) and then dividingRead More…

I am working to hydro-condition a watershed that has a heavily developed area. Sometimes water goes into storm ponds so I leave that impeded flow alone, but sometimes water flows into underground systems where I can’t find the output. In that situation, how should I handle incorrect impeded flow?

Is the urban area at the mouth of the stream or in the middle of the watershed? If it the urban area has no agricultural areas between itself and the mouth of the stream, no agRead More…

I am working on the Precision Conservation Practice Siting Tools and have run my files through the Depression Identification Tool. Now, I am trying to go through each polygon to see which are true or artificial depressions and having trouble. How do I know which should be deleted?

Images from the user: The first image is of some depressions that appear to be the result of drainage ditches. The second image looks like it is a true depression. Do you think this is correct?Read More…

My boundary and buffer polygons keep getting deleted. In the hydro-conditioning process I am running the D8 Processing Tool, running the PD Flow Network, running the Depression Depth Tool, adding cutlines feature class, creating cutlines and then running the Manual Cutter Tool. Afterwards, when I run the PD Flow Network or the Depression Depth Tool after making edits my boundary and buffer lines get deleted. Why is this happening?

I suspect that as part of your editing process you are inadvertently deleting features from the watershed boundary (bnd) and buffered boundary (buf) feature classes. If you set the feature class that you intend to editRead More…
