HEC-GeoHMS: A bacia hidrográfica não pôde ser delimitada a partir do ponto de saída!

Question

<\/HEAD>Eu tive o seguinte problema ao trabalhar com seu programa HEC-GeoHMS. Quero analisar a bacia hidrográfica que drena para o medidor de fluxo do riacho. Então, selecionei na barra de ferramentas do HEC-GeoHMS --> Configuração do Projeto --> Iniciar Novo Projeto. Defini um novo projeto e nomeei um ponto de saída. Então, quis gerar um projeto (--> Configuração do Projeto --> Gerar Projeto). Agora recebo a seguinte mensagem de erro: A bacia hidrográfica não pôde ser delimitada a partir do ponto de saída! Esse problema ocorre no software ArcGIS 10.2.2 e 10.4. Eu segui todos os passos conforme o Capítulo 13 do Manual do Usuário. Existe alguma solução para esse problema? <\/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.
