Hi all,
Long-time GIS user, but first-time water resources/H&H workflow question. I’m working on a project where consultants are developing separate HEC-RAS models for different drainage basins in our city, each producing flood surface results for various design storm events. Once all the modeling is completed, there’s a desire to generate a single multidimensional .crf layer of water surface elevations that represents the combined results of all models. The end goal is to create a smooth, time-enabled flood animation/analysis layer for our ArcGIS ecosystem.
I understand that consultants can export individual water surface .tif rasters for each model timestep, but this results in a very large number of files to manage, and I’d like to avoid unnecessary raster wrangling if possible.
My main questions:
- Is it possible for ArcGIS Pro to import native HEC-RAS output results (e.g., the RAS Mapper results folder or the simulation *.hdf file) directly, without requiring hundreds of exported TIFFs?
- If so, what is the best workflow to convert those native HEC-RAS outputs into a single multidimensional .crf suitable for time-enabled visualization and analysis?
- Are there best practices or considerations when combining outputs from multiple, separate HEC-RAS models into one coherent time-enabled raster layer?
Any guidance would be greatly appreciated. Thanks!
