Krey, did I really just watch you flood the Grand Canyon? :) Cool demo.

This was very helpful, thanks for sharing! I´d appreciate if you showed how to add shapes and polygons on the cloned terrain. Best regards

Hello Krey, In a time of video (23:50) you spoke about terrain modification for removing water surface form Dam accumulation, getting from Lidar (if someone want to make dambreak model). My quation is: Did we have some easies trick to remove water surface or we must use Terrain modification layer with multipoint polygon tool? (in second case we need a "meny meny" of polygons to make assumption of natural terrain before dam to be buildet)

Hi Krey, just wondering if you have any suggestions to fix my problem. I am running a 2D flow area (10x10 mesh) with channel terrain modifications (model runs fine without them) and variable time step method. The model keeps going unstable and not too sure what to try next. Using a 30s computational interval and max/min courant numbers of 2 and 0.75 as the terrain is in a steep sided narrow river environment so the velocities are relatively high. Cheers in advanced :)

Please help The issue I am facing is "has a weir elevation lower than the cells they are connected to for 2D Area Perimeter 1 This is not allowed in HEC-RAS: "

What if i added a high ground (as a dam) in the river and the app didn't identify it? the water flows as if there's no high grounds. what did I miss? can you help, please? thanks in advance!

i'm sorry but it's normal that doing a modification (high ground) the elevation of the vertices is lower than the terrain over i'v put it? just for an example, one vertex has elevation of 16.03 vs terrain in the same point of 16.67

Dear sir, why you need to resample from original srtm dem 30m to 100m resolution? and how to resample it in ras mapper?

Do i need to re-run the simulation when doing terrain modification or i just need to associate the modified terrain to the existing simulation file? thanks!
