How to assign top elevation to drain nodes ?

[Hila]

Hi,

I have a long drain arc, with many nodes, in my model. How do I assign grid top elevation to drain nodes in GMS 8 ?

Thanks,

Hila

Hila,

Create a tin around the drain arc. Interpolate the desired elevation data to the tin. You can select the tin elevation as drain bottom elevation in the attribute table of the drain coverage.

Redistribute Vertices (right click polygon arc) before creating the tin.

There is also a seepage face boundary condition that you can apply in the conceptual model. It will assign the grid top elevation as the drain elevation.
