Hi Luis, Thank you for your reply. I am alredy running the model using a Manning coefficient. But what I would like to know is how is the Manning coefficient used for calculating the bottom stress. I would imagine is something like: T=rho.g.n^2.u^2/h^1/3 where, T is the bottom stress, n is the Manni...

Hi, I am working with a 2D model and I have been imposing the rugosity as an absolute value (zo), using the logaritmic law. However, I wonder how can the model use a logaritmic law in a 2D configuration. A 2D model calculates the vertical integrated velocity, does it use this velocity to calculate t...

### Variable Wind in time and space

Hi,
I generated a wind field with an ascii file and I would like it to change the intensity with time. Is it possible to give as an input a time function for the intensity?
Regards,
Mariana

### HDF5Extractor for Linux

Hi,
I would like to know if the tool HDF5Extractor is compiled in Linux?
If that's the case, would you mind sending us the files to compile it?
Kind regards,

### Inverted Barometer

Hi, I have seen in the Mohid wiki (http://www.mohid.com/wiki/index.php?title=InvertedBarometer) that there is an application to modify the water level time series in tide gauge locations according with the inverted barometer effect. Could you please send me the Inverted Barometer executable? Thank y...

### ConvertToHDF5 - Mercator files

Hola Luis, Once again we are trying to use the Mercator results as OBCs for our hydrodynamic model. The Mercator people sent us the following files: ext-mask_float.nc ext-mesh_hgr_float.nc ext-mesh_zgr_float.nc ext-PSY3V2R2_1dAV_20070501_20070502_gridT_R20070502.nc ext-PSY3V2R2_1dAV_20070501_2007050...

### Tide Potential

Hi,
I would like to know which are the terms added to the balance equations when Tide Potential is set to 1 in the Hydrodynamic.dat file cause nothing is said in the Hydrodynamic or MOHID manual about it.
Best regards,

### Box Integration

Hi, I am modeling a domain with 12 thousands cells and I would like to compare the results (water levels mainly) of several simultions over the whole domain. As 12 thousands cells means far too many points of comparison I was thinking to integrate the results in different regions defined by boxes. T...

Hi Francisco,
Thank you for your reply but I am only introducing the tide at the boundary of the domain. I was using one tidal gauge for each cell and it didn't work. We tried skipping one cell every two cells (i.e. reducing the number of tidal gauges to one half) and it worked.
Cheers,

### Tide gauges from FES

Hi,
I have been doing some tests with the tidal input and I found that when I insert too many tidal gauges (1200 points approx.), the simulation does not run. Is there any limit on the number of points for the tidal gauges?
Thank you, cheers,
Mariana
