From CSDMS
This is a property of type Text.
W
Main inputs are bathymetry, riverine sediment discharge time-series, and ambient wave and current time-series. Critical velocity for sea bed erosion, bottom drag coefficient and critical bulk Richardson number can also be adjusted. +
D
M
Many, see Mudd et al. (2009) ECSS v 82(3) 377-389 +
W
Marsh vegetation and mudflat sediment characteristics
Backbarrier basin width
Reference wind speed
Tidal range
Reference sediment concentration +
Maximum gradient windspeed 10 m above water (m/s), Radius of maximum wind (km), Pressure difference between eye and ambient (mm Hg), Forward speed of hurricane (m/s), Maximum number of nodes in x direction (postive east), Maximum number of nodes in y direction (positive north), Space step in x direction (m), Space step in y direction (m), X location of eye (m), Y location of eye (m), Storm direction (degrees counterclockwise from east) +
S
Maximum number of timesteps over which winds computed, X-dir. position of storm center at beginning, Y-dir. position of storm center at beginning, Storm velocity (m/sec), Storm direction (degrees counterclockwise from east), Pressure at eye (Pascals), Pressure at edge (Pascals), Radius of maximum storm winds(m), Storm radius (m). +
F
Measured or artificially generated wave and current forcing. Floc diameter, density. Downslope gravity. Vertical grid mesh. Erodibility. Parameters for Bingham rheology. +
M
Microsoft Excel tables +
R
Minimum requirements include a river network with link id, downstream link id, upstream drainage area, link length, and link slope. All of these are attributes are included as part of the National Hydrography Dataset Version 2 Plus (NHDV2Plus). +

T
Model Inputs:
* Project file: Text description of application and input file names and paths.
* Catchment (watershed) data file: Watershed and subwatershed topographic index—ln(a/tan B) distributions and the following parameters:
** The mean soil surface transmissivity
** A transmissivity profile decay coefficient
** A root zone storage capacity
** An unsaturated zone time delay
** A main channel routing velocity and internal subwatershed routing velocity
To use the infiltration excess mechanism, a hydraulic conductivity (or distribution), a wetting front suction and the initial near surface water content should be added.
The initialization of each run requires an initial stream discharge and the root zone deficit.
* Hydrological input data file: rainfall, potential evapotranspiration, and observed discharge time series in m/h
* Topographic index map data file: the topographic index map may be prepared from a raster digital elevation file using the DTM-ANALYSIS program. This file includes number of pixels in X direction, number of pixels in Y direction, grid size, and topographic index values for each pair of X and Y. +
S
C
Model setup: grid extent and resolution, time stepping and duration.
Environmental inputs (from global datasets, automated methods): bathymetry, seawater bottom temperatures, benthic irradiance, seafloor hardness, ocean wave climate
Organism characteristics (automated from Knowledge Base): dimensions, construction, reproduction and survivorship +
B
Modify input parameters directly in Matlab script
Inputs include initial conditions, upstream flow conditions, bifurcation geometry, bypass fraction, sea level (optional), differential subsidence rate (optional) +
D
Modify parameter values in Matlab code directly:
Water/Sediment discharge;
Grid size and grid parameters;
Basin geometry;
Input sand/mud ratio. +
P
Modify parameters in example input file deltaRCM.yaml included in repository. Run with example script run_pyDeltaRCM.py.
Modify water/sediment discharge (as number of parcels), grid size and spacing, basin geometry, mud/sand ratio, etc +
M
Multiple parameter files, initial conditions matrices +
D
No files required. Sediment composition, vegetation parameters, SLRR, run time, grid size, water and sediment discharge and other similar parameters can be modified directly within the code. +
G
Note: See also the GEOMBEST++ Users Guide, section 6
A minimum of four excel files are required to run a GEOMBEST-Plus simulation: an “erosionresponse” file, an “accretionresponse” file, a “run#” file, and a “tract#” file. If the simulation involves a single coastal tract then the files must be titled “erosionresponse”, “accretionreponse”, “run1” file and “tract1.” Caution: Note that the run# and tract# files will have the same name (tract1, run1, etc., see below) for all simulations and so attention to organization is critical. +
