Spill Modelling on a Stream using Arc Hydro

Discussion created by tenzinrubling on Sep 6, 2012
Hello all,

I am trying to model a potential spill in a creek from an underwater pipeline using ESRI ArcGIS 10 and Arc Hydro 10.
I currently have LiDAR data for the area, the stream polyline, flow rate, shore type, shore width, and substance thickness.

What other datasets do I need in order to model this using Arc Hydro 10 tools?
What are the steps involved?

Any help with this is appreciated!
