Also known as
Model type Single
Model part of larger framework
Incorporated models or components:
Spatial dimensions 2D
Spatial extent Watershed-Scale, Reach-Scale, Patch-Scale
Model domain Terrestrial, Hydrology
One-line model description A coupled model for infiltration, fluid flow, and sediment transport.
Extended model description The model couples the shallow water equations with the Green-Ampt infiltration model and the Hairsine-Rose soil erosion model. Fluid flow is also modified through source terms in the momentum equations that account for changes in flow behavior associated with high sediment concentrations. See McGuire et al. (2016, Constraining the rates of raindrop- and flow-driven sediment transport mechanisms in postwildfire environments and implications for recovery timescales) for a complete model description and details on the numerical solution of the governing equations.

Describe input parameters [[Describe input parameters model::The following parameters need to be specified (in order) in a file called "input.txt":

nx – number of grid cells in x direction ny – number of grid cells in y direction dx – grid spacing F – Fraction of stream power effective in entrainment manning0 – minimum manning coefficient tend – end time for simulation a – detachability of original soil ad – redetachability of deposited soil h0 – critical flow depth in HR model mtstar0 – shielding parameter in HR model rnum – number of entries in rainfall input file rint – time interval (in seconds) associated with each rainfall intensity in the rainfall input file sclass – number of particle size classes Jentrain – energy expended entraining a unit mass of cohesive sediment

Other required input files: rain.txt: A file containing rainfall intensity in [m]/[s]. The file should contain "rnum" entries. The time interval associated with each rainfall intensity should be specified as "rint" in the input.txt file.

topoin.txt: elevation data for each point in the grid

particlepercentin.txt: A vector containing K entries that specify the percentage of soil consisting of sediment in each of the K particle size classes

particlesizein.txt: A vector containing K entries that specify the representative particle diameter associated with each of the K particle size classes]]

Describe processes represented by the model The model simulates infiltration, fluid flow, and sediment transport. Fluid behavior is influenced by sediment concentration.
Describe key physical parameters and equations The model couples the shallow water equations with the Green-Ampt infiltration model and the Hairsine-Rose soil erosion model. Fluid flow is also modified through source terms in the momentum equations that account for changes in flow behavior associated with high sediment concentrations. See McGuire et al. (2016, Constraining the rates of raindrop- and flow-driven sediment transport mechanisms in postwildfire environments and implications for recovery timescales) for a complete model description and details on the numerical solution of the governing equations.
Describe length scale and resolution constraints The model is designed to be used at the watershed scale or smaller.
Describe time scale and resolution constraints The model is ideal for simulating sediment transport in response to a single rainstorm.
Describe any numerical limitations and issues The Courant number must be less than 1 at all times to maintain stability.
