river merge problem in basin processing using ArcGIS via the Hec-GeoHMS extension

Hello! I use the Hec-GeoHMS 10.1 extension in ArcGIS 10.1. After merging 65 subbasins into one basin, I'm trying to river merge all individual streams unsuccessfully. The message from the above action is: disconnected rivers or rivers meeting at confluence can not be merged. I notice that all individual streams are meeting at a confluence. I would… (Show more Show less)

Sofia, you can manually delete river segments that will not be modeled as routing reaches through an edit session. I think you'll only use River Merge where you'll end up with one single continuous line that does not branch. Hope this helps. Kurt

HEC-GeoRAS Export Error

Using ArcInfo 10 and GeoRAS 10 I am attempting to create my export .xml and .sdf files to create my model. I have gone through the process with the tutorial in the users manual and it worked fine.

How to calculate volume of an open moraine?

I have a DEM of a glacial moraine the experienced a GLOF. I am trying to calculate the volume of drained water but since the basin is opened, I'm not sure if the surface volume tool will work (since the calculation would, in my understanding, take into consideration the downstream valley which would count as "below" the elevation plane assigned in… (Show more Show less)

Arc Hydro vs. Spatial Analyst

I'd like to do a weighted flow accumulation to measure the flow accumulation from impervious surfaces. I've also done some terrain preprocessing with ArcHydro tools (Level DEM and Fill Sinks). Is it important to run additional ArcHydro terrain preprocessing tools (stream definition, stream segmentation, drainage line processing, create… (Show more Show less)

HEC-GeoRAS and HEC-GeoHMS for ArcGIS 10.6

Hello! I know there is a version of HEC-GeoRAS and HEC-GeoHMS for ArcGIS 10.5. I need these two plugins for ArcGIS 10.6. Does anybody know where I can find such versions? I searched in this link, but for version 10.6 doesnt exist yet. Do I have to downgrade the arcgis version? http://downloads.esri.com/archydro/ Thanks

The most updated version of HEC-GeoHMS (10.5.0.7) was published on Aug 30, 2017. I highly doubt there will be future versions developed for HEC-GeoHMS. Whoever wants to use it would have to stick with ArcGIS 10.5 assuming all the tools work as intended. There is a similar question on Research Gate where posters had to downgrade to older…

Hi all! Is anyone else having trouble with the HEC GeoRAS download? I am using this location: yellow.esri.com - /archydro/HecGeoRAS/. I was able to download ArcHydro and HEC GeoHMS with no problems, but GeoRAS is getting stuck at a point in the download and just never finishes. Is there a mirror site or alternate ftp for this? I need the 10.3… (Show more Show less)

Flood Plain Delineation Stream from Point not Producing 3d Line Raster

Hello, I'm working on mapping a flood plain in a flood prone area. I have collected the data necessary (DEM, river feature, and gauge data), compiled it into a TimeSeries table, snapped the gauges to the line, and ran the Stream WSE from Point tool. The tool ran fine, I believe, however, the Line Raster did not appear in my catalog view. I found… (Show more Show less)
