)::Union{SedimentTransportModel, Nothing}

Initialize sediment transport model parameters.

Arguments

• model::ModelData
  • The model data container containing the model parameters and arrays.

Keyword Arguments

• iuse_downhill_diffusion::Int64
  • Integer flag that activates sediment transport model with downhill diffusion (0 = off, 1 = on). If option is set to off uniform erosion and deposition rates will be used
• subaerial_slope_diffusivity::Float64
  • Subaerial slope diffusivity in m^2/s. Typical value used in the literature is 0.25 m^2/yr (7.9e-9 m^2/s) (e.g. Andres-Martinez et al., 2019; Armitage et al., 2015)
• precipitation_rate::Float64
  • Precipitation rate in m/s used to calculate water flux in drainage basins for fluvial transport diffusivity model. Precipitation rate (m/s). Used to calculate water flux in drainage basins. Typical value used in the literature is 1 m/yr (3.2e-8 m/s) (e.g. Andres-Martinez et al.; 2019; Huffman et al., 2009).
• subaerial_transport_coefficient::Float64
  • Subaerial discharge transport coefficient. Used to calculate effective subaerial fluvial transport diffusivity that includes slope diffusivity, precipitation rate and downstream distances. Typical values used in the literature are 1e-4 (low transport) to 1e-2 (high transport) (e.g. Andres-Martinez et al., 2019; Armitage et al., 2015).
• submarine_slope_diffusivity::Float64
  • Maximum submarine slope diffusivity in m^2/s used in diffusivity model that decays exponentially with water depth. Typical value used in the literature is 100 m^2/yr (3.2e-9 m^2/s) (e.g. Andres-Martinez et al., 2019; Kaufman et al., 1991).
• submarine_diffusion_decay_depth::Float64
  • Submarine diffusion decay depth (m). Typical value used in the literature is 1000-2000 m (e.g. Andres-Martinez et al., 2019; Kaufmanet al., 1991; Perez-Gussinye et al., 2020).
• transport_timestep::Float64
  • Transport timestep (s). Typical value used in the literature is 1000 years (3.1536e10 s) (e.g. Andres-Martinez et al., 2019).
• pelagic_sedimentation_rate::Float64
  • Pelagic sedimentation rate (m/s). Typical value used in the literature are 0.3 mm/yr (syn-rift) to 0.01 mm/yr (post-rift) (e.g. Perez-Gussinye et al., 2020)
• pelagic_sedimentation_rate_reduction_factor::Float64
  • The pelagic sedimentation rate is divided by this factor after the specified pelagic sedimentation rate reduction time.
• pelagic_sedimentation_rate_reduction_time::Float64
  • Time in Myr after which the pelagic sedimentation rate is reduced by the pelagicsedimentationratereductionfactor.
• iuse_compaction_correction::Int64
  • Integer flag activating compaction correction during sediment transport where newly deposited sediment thickness and pre-existing sediment thickness are corrected for compaction.
