Significance of the File

contains general input data for the simulation of bed load transport for the numerical models TRIM-2D and TRIM-3D

File-Contents (in Catchwords)

  1. steering parameters for the simulated physical processes which are related to bed load transport (with/without bed load transport, with/without hiding effects between different sediment sizes, with/without sediment balance at the bottom, with/without morphodynamic evolution)
  2. rate of sea level rise and rate of land rise
  3. number of sediment fractions
  4. type of transport formula used (vanRIJN, BAGNOLD)
  5. parameters for the characterization of sediments
    • percentage of the fraction related to the total sediment mass
    • density
    • porosity
    • characteristic diameters D50 and D90
    • transport efficiency (BAGNOLD)
    • angle of deposition (BAGNOLD)
    • exponent for the transport formula (vanRIJN)
    • factor describing the influence of bed forms
    • factor for gravitational bed load transport
