RiverCAD® is a sophisticated river modeling software that completely supports HEC-RAS and HEC-2 within AutoCAD or its own stand-alone CAD environment. RiverCAD makes it even easier to compute water surface profiles for modeling bridges, culverts, spillways, levees, bridge scour, floodway delineation, floodplain reclamation, stream diversions, channel improvements, and split flows. RiverCAD reads and writes data from the latest versions of HEC-RAS and HEC-2.

Allows multiple orthophotos (raster images) to be displayed in the background
Raster image is fully integrated into the drawing, allowing transparent zooming, panning, and printing of the background along with the displayed modeling results
Images can be georeferenced and can be rubbersheeted to accurately match the image to real-world coordinates
Raster image commands include:

Move
Crop
Clear rectangle and polygon
Align
Rotate
Resize independently in X & Y directions

Snap to Raster command that allows you to quickly align a cross-section cut
Supports many raster image formats including:

Georeferenced TIFF (i.e., GeoTIFF)
JPEG
TIFF
GIF
PCX
BMP
