From CSDMS
This is a property of type Text.

D
Very little constraint; runs quickly on large grids. +
F
Wave-current BL, lengthscale ~1 m nearbed, grid size ~1mm; Tidal BL: lengthscale 10 m, grid size 1cm +
E
We use formulations describing rivers at large scale. Complex interactions between physical, chemical, biological and ecological processes that play a relevant role in floodplain construction are not accounted for, as their impacts on floodplain mass balance cannot be quantified. Model parameters should thus be interpreted as averages over a few meander bends, and over several years. +

With Matlab running on my desktop PC I get out of memory errors when I make the domain much bigger than it is at present (250x250). I am working to expand the model domain. I would also like to increase the resolution. (Isn't this what all modelers want to do?) +
C
With reasonable parameter values channel networks with individual channel of ~1000 nodes will take a few to 10s of minutes to analyse. The longer the channel network, the longer the analysis. +
G
With the current version of the code (DNS and no turbulence model) we are restricted to low Reynolds numbers. Up to maximum 10,000. +
S
With the current version of the code (DNS and no turbulence model) we are restricted to low Reynolds numbers. Up to maximum 10,000. +
T
W
B
cell size of the upstream two cells is an intrinsic model parameter, but downstream cell size can be chosen arbitrarily +
Z
T
domain needs to be large enough to capture the boundary layer, and the resolution ( on the order of grain size) should be fine enough to capture the sediment-fluid interaction near the bed level. +
G
global scale (5 to 100 km). gospl can be used with different mesh resolutions enabling better representation of surface processes in regions of interest (e.g., specific basins, continental regions) while using lower resolutions to save memory allocation in other parts (deep marine regions for example). +
