Trouble exporting data from ArcMap to Hec-Ras

[Adrian]

Hello! I have recently started working with Hec-Ras and will use it to simulate the potential re-suspension of deposited sediments when altering the current minimum discharge downstream a dam to a more dynamic flow (ecological flow scheme). So im just playing around with Hec-Ras to learn in and have encountered some problems:

1: I have created a stream in arcmap using HEC geo-RAS. The stream then looks like this

When i import the data to Hec-Ras, it comes up like this and everything seems fine

But when i import the exported file to Hec-Ras, the stream looks like this

Why is this? Why doesnt Hec-Ras import the stream as it were in ArcMap? If anyone could help me out id be very grateful.

I also have a problem when creating a terrain in RAS Mapper. The created terrain in Ras mapper looks like this

But when i try to open it in Hec-Ras geometric data, the colours are wrong:

As sson as i have changed anything in the terrain symbology, it goes back to default. Does anyone know how to fix this? Thank you in advance!
