Property:Describe length scale and resolution
From CSDMS
This is a property of type Text.
O
0.1 mm and below to ~1 km, depending on the scale of your problem and computational resources. +
C
T
1D
Uppermost 10 m has high resolution gridcells (0.05m).
Below 10 m to 500 m depth, grid cells are coarser (1m). +
H
S
A requirement is high resolution topographic data, typically ~1m resolution. For a detailed discussion of lengthscale and resolution constraints we urge the user to refer to the original manuscript +
E
A set of four examples is provided (eSCAPE-demo - https://github.com/Geodels/eSCAPE-demo) and illustrates the different capabilities of the code from synthetic to regional, to continental and to global scale models. +
G
Adaptive refinement allows using a very coarse grid on the ocean scale (e.g. 2 degree resolution) and several nested levels of refinement down to e.g. 1/3 arc-second (10 meter) resolution in specific coastal regions. +
T
All spatial data should be provided as projected, georeferenced (e.g., UTM) grids or shapefiles where spatial units are given in meters. Data referenced in a geographic coordinate system will return unexpected results. +
S
Alluvial channel morphology is not explicitly modeled; rather, channel width, depth, slope, and discharges of water and sediment are represented as sub-grid characteristics. Each cell contains at most one channel. +

Although the hillslope length and height are specified, these are dimensionless numbers from the perspective of the module. Accordingly, the resolutions supported by the module are primarily constrained by the language in which it is implemented. However, the process of "dimensionalizing" the module's outputs may place practical constraints on resolution. The associated paper discusses this issue. +
G
Analytical solution produces unrealistic results with low elastic thickness and/or very large cells due to the Green's function approximation. +
N
Angular resolution around the radar; gridded data typically have km-nmi-size pixels +
T
Applies to any resolution topographic grid, though is most sensible for grids with resolution from 2 to 50 m. +
R
Assumptions:
The REF/DIF 1 model, in parabolic form, has a number of assumptions inherent in it and it is necessary to discuss these directly. These assumptions are:
# Mild bottom slope.
# Weak nonlinearity.
# The wave direction is confined to a sector ±70 ◦ to the principal assumed wave direction, due to the use of the minimax wide angle parabolic approximation of Kirby (1986b). +
G
At the moment the resolution of the input controls the resolution of the output. This is a global model but can be applied to smaller domains. +
W
Available datasets are for global and continental domains. Realistic high-res simulations for global scale is 6 arc-min and for continental 3 arc-min. Higher resolution datasets are available for both (e.g. 15 arc-sec for Europe). +
G
Cell length - 10 - 100 meters
Cell height - 0.01 - 0.5 meters +
Cell length: 10 - 100 m (typically 50 m)
Cell height 0.01 - 0.5 m (typically (0.1 m) +
C
B
Coastal barrier ~10-100 km length scales, and ~100 m alongshore resolution. Parameterizations not suitable for small-scale (tidal inlet etc) analyses +
