Geo-Ras Overstromingsvlakte Afbakening met Rasters

Question

<\/HEAD>Ik gebruik ArcGIS 10 en Geo-Ras 10. Ik kan een GIS-project maken, alle gegevens exporteren naar HEC-RAS, mijn onstabiele simulatie uitvoeren en weer importeren in Arc-GIS zonder problemen. Vervolgens stel ik mijn lagen in, importeer de lagen en voer een wateroppervlaktegeneratie uit. Echter, bij de laatste stap, Overstromingsvlakte Afbakening met Rasters, crasht het programma.<\/SPAN> Ik heb nieuwe projecten aangemaakt, alle stappen opnieuw gedaan, bestanden verwijderd, bestanden lokaal opgeslagen, de computer opnieuw opgestart. Ik kan niets anders bedenken dat het probleem zou kunnen veroorzaken. Alle advies wordt gewaardeerd. Ik heb ook een tijdelijke oplossing gebruikt, waarbij ik de TIN minus gebruik om te genereren wat ik nodig heb, maar ik heb veel projecten waarvoor ik dit steeds moet doen en wil dit graag oplossen.<\/SPAN> Nick<\/SPAN><\/BODY><\/HTML>

I am using ArcGIS 10 and Geo-Ras 10. I am able to create a GIS project, export all data to HEC-RAS, run my unsteady simulation, and import back into Arc-GIS just fine. I then set up my layers, import the layers, and do a water surface generation. However, on the last step, Floodplain Delineation Using Rasters, the program crashes.

I have created new projects, redone all steps, deleted files, saved files locally, restarted the computer. I can't think of anything else that would cause the issue. Any advice would be appreciated. I have also done a work around, using the TIN minus to generate what I need, but I have many projects that I need to continually do this for, and would like to figure this out.

were you finally able to resolve the issue??? am facing a similar problem.

If anyone else has given up and wants to use a work-around, I've had success with taking the TIN produced in the "Water Surface Generation" step and intersecting it with the ground surface TIN using "Surface Difference" in the 3D Analyst Tools -> Terrain and TIN surface toolbox.

Best of luck.

I am having the exact same problem in GeoRas10 and ArcGIS 10 (even using the same work-around), but haven't found any solutions yet. For whatever it is worth, as recently as July 2012 I was successfully generating floodplain delineations using GeoRas10 and ArcGIS 10, but now returning to the process a couple months later, the final "Flood Plain Delineation Using Rasters" step doesn't work.

I might have missed something, but I wasn't able to find anything in  h2obuilding's suggested thread that is relevant to HEC-GeoRAS tools.
