Gabion Wall

Post by ccolinea »

Dear ENVI-met team,

I would like to modelize a gabion wall :

Do you have an idea of the initial material I should use to create my gabion wall and wich paraleters I should adjust ?
This type of wall is supposed to absorb the wind and thus, improve thermal confort. I would like to quantify this element and make a comparison with a default wall..
Best regards,

Clara

Hi Clara,

I think I would take the brick material as basic material and of course change the albedo because 0.4 is too high. You could then either digitize the wall as very thin building or as SingleWall.

Best regards,
Tim

Hi Tim,
Thanks for your answer. But is there a way to modelize the voids index of gabion wall ? In order to modelize the wind going through the stones ?
Otherwise, while checking the database, I noticed that the sandy soil had a albedo value of 0. Is that normal ?
Best regards,
Clara

Hi Clara,

Yes, albedo of natural soils is modified during the simulation depending on water content and sun position.
Wind going through walls cannot be simulated. You might consider to build the wall alternating between a free grid cell and a cell with the wall and so on.

Best regards,
Tim
