If the movie does not play in this window, download it (AVI, 2.39 Mb) and view with a separate movie player.
If you don't have a movie player that allows fine control over frame advancement and reverse, consider obtaining one. For the Mac and Windows environments, try the free QuickTime viewer from Apple. For Unix systems, try the free xanim viewer.
Movie of Data in Figure 6. Depth-averaged point velocity distributions for the 100-year flood event through the proposed Roc Roe Bayou bridge opening. This scenario simulated the bridge opening in a fielded area, with no riprap present around the left abutment; the new opening is downstream 425 feet from the existing bridge. This animation illustrates an increase in the depth-averaged point velocity through the bridge opening, with the fastest velocity occurring near the left abutment. The maximum depth-averaged point velocity increased 29% from existing conditions.
This movie is part of a paper entitled "Effects of a simulated change in land cover on surface-water velocity distribution at a bridge in southeastern Arkansas" by Barks and Funkhouser, which can be found at http://smig.usgs.gov/SMIG/features_0902/roc_roe.html
