maybe there is a problem with the auto-adjustment of dowstream lengths?]]> http://www.bossintl.com/forums/showthread/s/1/threadid/16648.html Tue, 16 Mar 2010 10:24:49 -0600
changing the date format worked...

now hopefully this new date format won't mess up another software!]]> http://www.bossintl.com/forums/showthread/s/1/threadid/16632.html Tue, 16 Mar 2010 09:40:21 -0600 I did some modifications to the regional settings in my windows seven system.
I'm not sure but i think it's the solution for all french HECRAS users.
Yannb : you have to install both french and english regional settings and setup your regional settings (specifically the date format MM/dd/yyyy).
Tell me if it work and if not you can contact me directly at [email]sgaiji@yahoo.fr[/email].

when i try to run stephane's file i get the same error he does during the post process.

note: i also use a french operating system.

i guess i'll model my reservoirs as sections rather than storage area for dambreaks!

edit: i just tried to run the example for dambreak provided with hec-ras and it yields the same error]]> http://www.bossintl.com/forums/showthread/s/1/threadid/16632.html Tue, 16 Mar 2010 04:09:58 -0600 Ever since I upgraded to Hec-Georas 4.2.92 for ArcGIS 9.3 i have the following errors while trying to export data:
1) When running the Elevation tool in Stream Centerline Attribute Tools or XS Cutline Attribute : Error 91 "object variable or with block variable not set".
2) When trying to export RAS data:
- classic export works but once import in HEC-RAS 4.1, when trying to view the cross sections, it says no data plot
- new export method does not work at all: C
:\Program Files\HEC\HEC-GeoRAS\bin\NewRasControl.xml does not exist!
I would appreciate some help.]]> http://www.bossintl.com/forums/showthread/s/1/threadid/16651.html Tue, 16 Mar 2010 03:47:47 -0600

Thanks]]> http://www.bossintl.com/forums/showthread/s/1/threadid/16645.html Mon, 15 Mar 2010 23:17:57 -0600 I created a model in Hec Ras 3 which aligned with the picture I had loaded in. I recently switched to HECRAS 4 which has now skewed all my cross sections so they aren't perpendicular to the alignment any more. I haven't changed my skew or downstream reach lengths. Does anyone know what might have caused this or what I can do to fix it?

2:
My model involves ramping rates of an upstream boundary condition (Power station). When I do my transient analysis, the calculation runs fine. But the data doesn't show up anywhere, all I can see is the results of the various profiles I ran for steady state analysis. When I go to the animations, The program shows all the diferent steady state profiles instead of the transient case.

Any help would be a god send!]]> http://www.bossintl.com/forums/showthread/s/1/threadid/16650.html Mon, 15 Mar 2010 15:40:21 -0600
You can not have special characters is directory pathnames or file names (you have a special character in your pathnanme - "...Documents/joão/GIS/..."). This is an issue on the HEC-HMS known problems page. Try saving the project to a directory that has no special characters in the pathname.

After I interpolate the corss sections, they appear in the geometry data page just how I want them.

However, after I go into the channel design/modification page and insert new templates into the template column and click the "Create a Geometry File with these Modifications," and click ok, and I go back to the geometry data page, the interpolations seem to have moved down the river and get pushed closer together too. The 3-D image verifies that that corss sections have moved. Also, it is only the interpolated cross sections that have moved, not the original ones. I am attaching a picture that show what the cross sections look like after I hit the "Create a Geometry File with these Modifications" button. You can see how the cross sections are bunched together when they should be spread out evenly.

So, I am just wondering if I am doing something wrong, and if I am, how can I fix this problem?

Thanks so much]]> http://www.bossintl.com/forums/showthread/s/1/threadid/16648.html Fri, 12 Mar 2010 10:54:09 -0700 Operations Decision -> there is an allowance for 1 month time setp.

I am trying to develop a ResSim model to determine reservoir sizing. When trying to run a simulation, the maximum time step model allows me to use is 1 DAY. Can we run the model at 1 MONTH time step?

I know that we could run the model with monthly time step in HEC-5 but I can not seem to find it in ResSim.

In the reservoir editor ->Operations Decision -> there is an allowance for 1 month time setp. But I believe this is only for operations decision.

Any help in this regard is highly appreciated.
