Einzugsgebietsfläche stromaufwärts vom Punkt

Question

<\/HEAD>Hallo. Ich muss die Fläche des stromaufwärts gelegenen Einzugsgebiets von Schnittpunkten zwischen einer vorgeschlagenen Trasse und Oberflächengewässern berechnen. Ich habe die ArcHydro-Tools noch nie verwendet und wurde von der USGS StreamStats-Website darauf hingewiesen und frage mich, welche Methode am besten geeignet ist, um diese Informationen zu erhalten. Ich schätze jede Hilfe – nur ein Hinweis in die richtige Richtung, um anzufangen. Ich verwende ArcGIS 10.4. Vielen Dank!<\/P><\/BODY><\/HTML>

Hello everyone. Well, it turns out the the StreamStats ended up working which saved me TONS of time. I think I must've been trying to use the application as they were finalizing v4 development because the last day I tried using it everything came together.

I appreciate everyone's help and input. Thanks!

Another helpful tool set can be found using HEC-GeoHMS. This is a free ArcMap tool that has the basics of the Arc Hydro tool.

The geoprocessing tools for Arc Hydro are in this tool but they are somewhat simplified. That is, you could use the GeoHMS tools just like the Arc Hydro tools. GeoHMS was created by ESRI for the US Army Corps of Engineers Hydraulic Engineering Center (HEC). It has additional tools to build HEC-HMS models, something I suppose you don't need. When you install HEC-GeoHMS it will also install the compatible Arc Hydro tools.
