Hi to all,

I'm studing a slope stability with a phreatic surface. I want to understand some parameters to define the flow through surfaces that are a little incomprehensible for me now.

1.)To define the the flow through a Drainage only surface i have to define a Ks (that Abaqus Manual name: seepage coefficient). How i Can define it?

2.) Also to define a surface pore fluid flow also i have to define the a pore pressure that is named as " some reference valure of pore pressure" and have symbol "uw infinite" §33.4.7. Can someone descrive better this value?

Any help will be appreciated!

Thanks
