			====748.7.3.9.4 GEO File (Stream Crossings)====
			GEO files contain geographic information that is imported into HEC-RAS to create the geometric portion of the hydraulic model. If survey data is provided for more than one stream, a GEO file is created for each stream. If additional sections or offset profiles are needed beyond what is available in the GEOPAK to HEC-RAS Converter spreadsheet, create multiple GEO files using the same streambed profile.

			A [http://caddnet/index.php?title=Road_Support_Training#Bridge_Survey GEOPAK to HEC-RAS Converter and tutorial videos] are available. The GEO file(s) and the GEOPAK to HEC-RAS Converter spreadsheet(s) are submitted with the Bridge Survey.
