Seep2D help

Recommended Posts

Hi all,

i have constructed a 2D model in GMS for calculation of SEEPAGE.

I have a DAM in which water table on one side is at 171 m and on the other on 169.0 m. In dam there is a jet-grouting sheet which has a very low permitivitty.

I have also 4 layers with such conductivity factor k (from top to bottom):

1) k.1 = 5 x E-5m/s,

2) k.2 = 1 x E-7m/s,

3) k.3 = 5 x E-5m/s

4) k.4 = 1 x E-9 m/s

The situation is shown in the attached picture.

When I run the model i get the result for total flowrate = 0.0000 m^3/s/m. Why? Also i do not get any flow lines? WhY?

I have tried to figure this out, but i cant. So any help is very appreciated.

Thank you, m

Matevz,

You may want to check your units. They should be consistent each time your are entering parameters for the model. The "Edit | Units" dialog should be set up correctly, and these units should be used in each subsequent step.

In the "Seep2D | Analysis Options" dialog, is the "Compute flow lines" check box activated? If not, it should be in order for them to appear.

Regards,

Todd

Hi Todd,

i' ve tried changeing the units. I get flowrate, but still there is no flowlines?!

I've also sent the GPR file with this project to support@aquaveo.com.

Hope you'll get this file...

thank you
