Modelling Rivers

River

Rivers are natural water courses. They have vital contributions to the social and economical welfare of societies living along their course. They provide continuous, usually dependable, flow and supply of water. Accordingly, centralised civilisation began emerging independently along number of river valleys; e.g. the Nile, Tigris and Euphrates, the Indus and the Yellow Rivers. Since then, mankind has been in continuous struggle to understand and live in harmony with this gift/force of nature. Modelling rivers is the modern way to understand their behaviour and is an essential tool to tackle several river problems.

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

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
