I’m working on bridge modeling in QGIS and HEC-RAS, and I have a doubt regarding street-level imagery.

Is there any way to use Street View–type imagery directly inside QGIS and draw or inspect bridge features from there?

I want to:

- visually inspect bridge piers and deck geometry

- estimate approximate clearance/low chord

- identify bridge type and embankments

- compare street-level view with satellite measurements

Basically I’m trying to understand the best workflow when official bridge drawings are unavailable.

What plugins or methods do you recommend for this kind of preliminary bridge geometry estimation in QGIS?

Hi,

I’m currently learning HEC-RAS and trying to improve my practical understanding of hydraulic modelling and flood simulations. If anyone is comfortable sharing some of your old HEC-RAS projects/models (academic, practice, or any professional examples with non-sensitive data), it would really help me assess and improve my workflow and understanding.

I’m especially interested in:

- River/flood modelling projects

- 1D or 2D simulations

- Bridge/culvert modelling

- Terrain preprocessing workflows

- Manning’s n calibration examples

- Real-world project structures and organization

Hello!

I’m working on a river modeling project in HEC-RAS and I'm still a beginner and had a couple of practical workflow questions:

1. What’s the most efficient and accurate way to draw cross-sections perpendicular to the river channel?

   - I’m currently using GIS (QGIS) to digitize them, but ensuring true perpendicular alignment along a meandering channel is tricky.

   - Are there recommended tools, plugins, or workflows (centerline-based, stationing methods, or automated XS generation) that work reliably?

2. How do you accurately determine bank stations in a cross-section profile?

   - Do you rely purely on DEM breaks in slope, field survey data, or visual judgment?

   - Any best practices to distinguish main channel vs overbank areas, especially in flat or subtle terrain?

Would appreciate any tips, workflows, or common mistakes to avoid—especially from people working with GIS + HEC-RAS integration.

Thanks!
