Perhaps you can just gut off the cross section points beyond the 100-year high ground? There's also the option of breaking off the cross section beyond the levee and putting it into an offline SA or 2D area, connected by a lateral structure.

I inserted a right bank station levee to prevent my 10 and 25 year water surface elevations from continuing to extend even beyond what topography will allow. However I need to insert another right bank station levee in order to prevent the 100 year from doing the same. Is there any way to accomplish this task?JRnoreply@blogger.comtag:blogger.com,1999:blog-1675184707067447729.post-12593905756282470162018-07-05T01:30:23.924-07:002018-07-05T01:30:23.924-07:00Hi Sir, I am currently working on the assessment o...Hi Sir, I am currently working on the assessment of dike and I find your method interesting and suits my needs, can I ask for a video or screen recording of that project?

The road is about 100 m far from the river and in case of flood it works like a levee for the flow. <br />At certain points, the road is crossed by 4 tunnels (square section about 3.5 x 3.5 meters) which, in case of flood, allows the water to flow under the road and reach the fields on the other side. My question is: "How can I model this tunnels? Are they like culverts?"<br /><br />Thank you so much.<br />Antonio.Antonio Francipanehttps://www.blogger.com/profile/11190616395190447612noreply@blogger.comtag:blogger.com,1999:blog-1675184707067447729.post-39168962878667025732017-05-24T07:56:50.504-07:002017-05-24T07:56:50.504-07:00If you have GIS and are comfortable with it, there...If you have GIS and are comfortable with it, there's not much of an advantage in preparing the terrain in HEC-RAS, other than the convenience of not having to switch between software applications.

I usually prefer doing terrain modifications like this in GIS and simply adding new data-sets. I feel that the manageability and editing options-tools of 3D shapefiles is much better for this purpose, than that of a river reach. <br />cheers,<br />martonmandarinhttps://www.blogger.com/profile/15427097765423693526noreply@blogger.comtag:blogger.com,1999:blog-1675184707067447729.post-58986310129338750512016-07-22T16:13:23.922-07:002016-07-22T16:13:23.922-07:00Make sure you are "adding a new cross section...Make sure you are "adding a new cross section", not copying an existing cross section.

However, you could do a lot of work with n values in 2D areas by reading/writing to the geometry file. The new version of RAS 5.0 beta allows for spatial definition of Manning's n values directly in the geometry schematic. These are presumably then stored in the geometry text file, which can be read from/written to via code (VBA or otherwise). Chapter 4 in my book talks about reading and writing to the geometry text file from a programming environment.

I ask this mostly with varying overland Manning's values in mind. I recently used RASController with VBA to vary cross section Manning's n values in a 1D model. Having also recently worked on analyzing the impacts of a new development with RAS 5.0, I wondered if this had come up at all.jmaynard90https://www.blogger.com/profile/09918348236822151730noreply@blogger.com
