HEC-GeoHMS: Watershedは出口点から区画できませんでした！

Question

<\/HEAD>HEC-GeoHMSプログラムを使用して作業中に次の問題が発生しました。流量計に流れる流域を解析したいと思います。そこで、HEC-GeoHMSツールバーで --> Project Setup --> Start New Project を選択しました。新しいプロジェクトを定義し、出口点に名前を付けました。次に、プロジェクトを生成しようとしました（--> Project Setup --> Generate Project）。すると、次のエラーメッセージが表示されます：Watershedは出口点から区画できませんでした！この問題はArcGISソフトウェアの10.2.2および10.4で発生します。ユーザーマニュアル第13章のすべての手順を実行しました。この問題に対する解決策はありますか？ <\/P><\/BODY><\/HTML>

I was also facing the same problem, but then I have installed Arc-GIS 10.1 and along with the Arc-Hydro tools 10.1 and Hec-GeoHMS 10.1. Also, try to create the input files from Arc-Hydro tools and then proceed directly to the step where you have to create project ("Project Setup"). For that, initially you have to input all the files in the Data Management of the Project Setup toolbar.

One thing that may be contributing to this is the presence of spaces and a potentially restricted character (the dash) in the file paths.  Remedy this for your Flow Direction Grid by adding underscores to Neuer Ordner where there are spaces and just to be safe remove the dash. Check all your other data to see if this is an issue.

Raster processes have much more specific file naming conventions than typical GIS files, so this could be what is causing the problem.  Unfortunately, there is not an explicit error that will come up advising the user that spaces and restricted characters are present and therefore causing a problem.

I had the same problem. Verify your AdjointCatchment, for me it was empty! And not forget that the layers should be save in the Geodatabase.
