Subject: Re: Roots detection in soil
Dear Massimo
With regard to the effects of vegetation on the stability of slopes, I would
like to mention that it is commonly believed that vegetation, if selected
carefully and managed properly, can have considerable stabilising effects on
surface movements and shallow seated instability, up to 4m deep. However,
for deeper seated instability, the beneficial effects of vegetation are
generally regarded as insignificant or minimal.
The subject is widely discussed in literature and you may find the following
sources useful:
Coppin, N J and Richards, I G (1990). Use of Vegetation in Civil
Engineering. CIRIA.
Greenwood, J R, Morgan, R P C and Short, J N (1996). Bio-engineering: a
field trial at Longham Wood Cutting, M20 Motorway. CIRIA Special Publication
128.

Subject: Roots detection in soil
I am looking for a reliable method to estimate the average depth of
penetration of some trees' roots in the soil. This is to evaluate the
potential use of some trees species to stabilise shallow landslides. Has
anyone experience on this subject?
Thanks in advance,
Massimo Schinelli
