Collecting, transporting and storing water in karst settings of southern Italy: Some lessons learned from ancient hydraulic systems

The karst landscapes of southern Italy, even though they show a lack or scarce presence of water at the surface, host a variety of ancient hydraulic works realized to collect and store water resources, to the advantage of the local settlements and for agricultural purposes as well. Ancient populations were forced to gain a deep knowledge of the territory in order to exploit the few available water resources, and developed for this aim several techniques, reaching a high level of capability to collect, transport, and distribute water, even at long distances. Many areas in southern Italy still nowadays present hydraulic works of remarkable interest and historical value, which are briefly described in the present paper, together with other features used for water storage in karst. Studying these ancient works, and safeguarding them, should be a priority aimed at educating the young generations toward a sustainable use of the water resource. © IWA Publishing 2013

InterPACIFIC project : comparison of invasive and non-invasive methods for seismic site characterization. Part I : Intra-comparison of surface wave methods

The main scope of the InterPACIFIC (Intercomparison of methods for site parameter and velocity profile characterization) project is to assess the reliability of in-hole and surface-wave methods, used for estimating shear wave velocity. Three test-sites with different subsurface conditions were chosen: a soft soil, a stiff soil and a rock outcrop. This paper reports the surface-wave methods results. Specifically 14 teams of expert users analysed the same experimental surface-wave datasets, consisting of both passive and active data. Each team adopted their own strategy to retrieve the dispersion curve and the shear-wave velocity profile at each site. Despite different approaches, the dispersion curves are quite in agreement with each other. Conversely, the shear-wave velocity profiles show a certain variability that increases in correspondence of major stratigraphic interfaces. This larger variability is mainly due to non-uniqueness of the solution and lateral variability. As expected, the observed variability in V-s,V-30 estimatesis small, as solution non-uniqueness plays a limited role
