If the movie does not play in this window, download it (AVI, 2.12 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 7. Depth-averaged point velocity distributions for the 100-year flood event through the proposed Roc Roe Bayou bridge opening with additional forestation. This scenario simulated the bridge opening 425 feet downstream from the existing bridge. In this simulation, floodplain vegetation was added to the fields upstream and downstream of the opening (increasing Manning's n by 67%) and riprap was added around the left abutment. This animation illustrates slower velocities around the left abutment with the fastest depth-averaged velocity occurring in the middle of the channel. This decreased the maximum depth-averaged point velocity by 38% from the initial proposed Roc Roe Bayou bridge opening.
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
