hec geo ras error

NargizRasulova — Fri, 12 Oct 2012 09:54:12 GMT

Hello everyone,
I'm working with Hec-Ras and HecGeoRas extension for ArcGis 9.3 version and using it for doing inundation map.

I am having problem with the next step. When I select the "Downstream Reach Lengths" (Ras Geometry>XS Cut Line Attributes), I get the following error message:

CalcXSReachLenghtsWK20001:Linetype attribute not populated for flow path feature OID=1

Can anyone help what's the problem?
Thanks

In the flowpath shapefile you need to set which flowpath line is the left, channel and right. On the GeoRAS toolbar there is a icon with 3 parallel lines pointing down. Click on that and then each of your flowpath lines setting the appropriate value.

Thanks, but these commands were given. The above problem was still...

Could you post a screen shot of the flowpath file attribute table? What I posted before should have fixed that error since all it is saying is that for your first flowpath entry the linetype hasnt been filled out.

I also noticed that your screenshot you posted before had a file name in Cyrillic...Sometimes geo-ras has weird issues with versions of arc other than the english version. You could try switching to english(if it isnt already) and try that. It has worked for people in the past.
