intro story Coast / Estuary

Coast / Estuary

Coastal systems are among the most dynamic physical systems on earth and are subject to a large variety of forces. The morphodynamic changes occurring to coastlines worldwide are of great interest and importance. These changes occur as a result of the erosion of sediments, its subsequent transport as bed load or suspended load, and eventual deposition. 
 
Estuaries are partly enclosed water bodies that have an open connection to the coast. Estuaries generally have one or more branching channels, intertidal mudflats and/or salt marshes. Intertidal areas are of high ecological importance and trap sediments (sands, silts, clays and organic matter).
Within the Delft3D modelling package a large variation of coastal and estuarine physical and chemical processes can be simulated. These include waves, tidal propagation, wind- or wave-induced water level setup, flow induced by salinity or temperature gradients, sand and mud transport, water quality and changing bathymetry (morphology). Delft3D can also be used operationally e.g. storm, surge and algal bloom forecasting.

error about using space varying wind and pressure in additonal parameters

In my simualtion, I provide the space varying wind and pressure using the addtional parameters in Delft3D-FLOW. When I run it, there is a problem. In the diagnosis file,it is read:
"*** WARNING File will not be created - Inconsistent comm. file times
*** ERROR Flow point outside meteo grid (x-dir) x,y,: -1.0 0.0
*** ERROR Flow exited abnormally "
Could someone help me ?
Thanks in advance!

Hi Ming Zhou,

The full FLOW grid must be covered by the meteo grid.
The error says that there is a point in the FLOW grid (x=-1.0, y=0.0) that is not covered by the meteo grid.

The manual contains detailed information for each type of meteo file that can be used as input. Please read it carefully.

Regards,

Adri

Hi all

I created my meteofiles using excel and converted into ascii file acoording to the Delft3D-WAVE manual. When I try to use I am getting following error.

Error in meteo module: Error reading block in meteo_on_equidistant_grid file in colnr, rownr : 1 3
Stopping WAVE computation.

I am including my meteofiles here. Please help me.

Hi, Everyone

 I got this error when i try to run a flow model with space varying wind

*** ERROR Flow point outside meteo grid (x-dir) x,y,:     914.3     652.2 
it's a little bit confusing because my flow grid didn't last until that position/coordinate

could someone help me to solve this problem

Thanks.

Regards, Giovanni

Hi all,Have any of you solved this problem? Or figured out what those coordinates correspond to?I am having a similar error "Error in meteo module: Flow point outside meteo grid (x-dir) x,y,:      25.9       4.6" despite my grid extents being between 49-56 latitude and -10 - -2 longitude so I don't understand what the flow point corresponds to.
Also based on my understanding of the meteofiles they encompass those areas so I'm guessing it's something fundamental I'm doing wrong.

In my case, part of the flow grid wasn't covered by the meteo grid. It was simple to solve.

The relationship between the two common measures of tropical cyclone intensity, the central pressure deficit and the peak near-surface wind speed, is a long-standing problem in tropical meteorology Upsers
