Are you looking for Soil Bioengineering? Ou, em português,  Engenharia Natural?

It is my offer: search "Sathananthan" and "Indraratna" as author of some paper, related to preloading and drainage of clayey soil. 

Also, I have an article in production about them and will release it as soon as possible.

I have some articles about the behavior of embankment and earth dams during construction and first impounding. Firstly I evaluated the instrumentation data, then numerical analysis has been conducted by FLAC software and finally both results have been compared by back analysis.

The result of settlement , pore water pressure and stress in clay core was evaluated in some dams like: Gavoshan rockfill dam, Shirin-dare earth dam and siah Sang embankment dam. All of this research would be available at my profile.
