River Inflow Velocity Define

[gegujang@lycos.co.kr]

In Hydrodynamic module,

I want to define velocity of river water as estuarial mouse input boundary.

As like below is defined by me. Is it right? and In Hydrodinamic_1.dat file,

where the keyword do I define below result will excuted?



TIME_UNITS : HOURS
SERIE_INITIAL_DATA : 2005 3 1 0 0 0

HOURS Vel_modulus
<BeginTimeSerie>
0.00 1.0
3.00 1.5
6.00 2.0
<EndTimeSerie>

Hi,

You can not define velocity (m/s) in your discharge. You must define flow (m3/s).

To activate the discharges option in the Hydrodynamic module, the keyword is

WATER_DISCHARGES : 1

This connects the Hydrodynamic module to the Discharges module.
In the Discharges data file you must define the location and characteristics of the discharge. Thus, in your case you must define the grid cell that corresponds to your estuary mouth's. This has been explained by Frank in a previous post (http://www.mohid.com/forum/viewtopic.php?t=159)

You can check also in the samples that come with the installation package. Also in the Hydrodynamic module user manual there is information on how to do this.

Hope this helps,
Luis

It's not possible to discharge velocity, like Luis said, but it is possible to associated a momentum to the discharge. Is this what you are looking for?
