This package adds two new modules (operators) to ANUGA. These are appropriate for reach-scale simulations of flows on mobile-bed streams with spatially extensive floodplain vegetation. The mathematical framework for the sediment transport operator is described in Simpson and Castelltort [2006] and Davy and Lague [2009]. This operator calculates an explicit sediment mass balance within the water column at every cell in order to handle the local disequilibria between entrainment and deposition that arise due to strong spatial variability in shear stress in complex flows. The vegetation drag operator uses the mathematical approach of Nepf [1999] and Kean and Smith [2006], treating vegetation as arrays of objects (cylinders) that the flow must go around. Compared to methods that simulate the increased roughness of vegetation with a modified Manning's n, this method better accounts for the effects of drag on the body of the flow and the quantifiable differences between vegetation types and densities (as stem diameter and stem spacing). This operator can simulate uniform vegetation as well as spatially-varied vegetation across the domain. The vegetation drag module also accounts for the effects of vegetation on turbulent and mechanical diffusivity, following the equations in Nepf [1997, 1999].]] Keywords: sediment transport, vegetation, flood, Name Mariela Perignon Type of contact Model developer Institute / Organization University of Colorado - CSDMS Postal address 1 Postal address 2 Town / City Boulder Postal code 80309 State Colorado Country United States Email address perignon@colorado.edu Phone Fax Supported platforms Unix, Linux, Mac OS, Windows Other platform Programming language Python Other program language Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development Does model development still take place?
