Velocity calculation in GMS

Recommended Posts

Hello,

Can anyone please tell me that how velocity is calculated from flow data in GMS(not through GUI).

Though I had already referred to the following the link:

https://www.aquaveo.com/blog/2012/05/15/velocity-vectors

,the velocity calculated by me is not matching the velocity obtained through GMS.

I had applied the following for the calculation of velocity:

 V = Q/(saturated_area*porosity);

where,

Q is the flow through a cell face, obtained from ccf file,

Saturated area = (head-bottom_elevation)*cell_width {for unconfined aquifer}

and head is obtained through .hed file.

Thanks in advance. Have a great day!
