| Zusammenfassung |
The hydrogeological characteristics of roto-translational slides in flysch
are complex, due to the inherent anisotropy and heterogeneity of rock masses
and related deposits. The paper deals with the hydrogeological
characterization of a reactivated roto-translational slide affecting
Cretaceous flysch rocks, located in the northern Apennines of Italy.
Continuous monitoring of groundwater levels, in-situ permeability and
pumping tests, hydrochemical and physical analyses and Uranine tracers were
the adopted prospecting methods.
In this research hydrological monitoring and investigation are summarized in
order to define a hydrogeological conceptual model of the landslide source
area. Results showed that two overlaying hydrogeological units exist at the
slope scale: the first is unconfined, but highly compartmentalized, and
hosted in the fractured and dismembered rock slide body. The second is
confined and lays in the undisturbed flysch below the sliding surface. The
groundwater level in the confined hydrogeological unit is twenty
meters higher than the groundwater level in the uppermost one.
Moreover, the groundwater chemistry characterization revealed a rising of
deep fluids in the landslide area. |
