    Description: In this study we present a procedure for the topographic classification of Italy, taking advantage of existing high resolution digital elevation models (DEM), with the support of routines embedded in Geographic Information Systems. The proposed method is based on morphometric analyses of a DEM, allowing for hilltop ridge detection, slope computation, identification of reliefs with potential topographic site effects, and topographic classification according to the indications of the current European and Italian seismic codes. The developed procedure can be applied worldwide and has a potential engineering interest for a fast and accurate topographic classification of a site, for both scientific and application purposes. The topographic classification of Italy is tested on several well known cases of topographic amplification and it is adopted for the topographic classification of Italian accelerometric stations.

    Description: The velocity and dynamic pressure of debris flows are critical determinants of the impact of these natural phenomena on infrastructure. Therefore, the prediction of these parameters is critical for hazard assessment and vulnerability analysis. We present here an approach to predict the velocity of debris flows on the basis of the energy line concept. First, we obtained empirically and field-based estimates of debris flow peak discharge, mean velocity at peak discharge and velocity, at channel bends and within the fans of ten of the debris flow events that occurred in May 1998 in the area of Sarno, Southern Italy. We used this data to calibrate regression models that enable the prediction of velocity as a function of the vertical distance between the energy line and the surface. Despite the complexity in morphology and behaviour of these flows, the statistical fits were good and the debris flow velocities can be predicted with an associated uncertainty of less than 30% and less than 3 m s-1. We wrote code in Visual Basic for Applications (VBA) that runs within ArcGIS® to implement the results of these calibrations and enable the automatic production of velocity and dynamic pressure maps. The collected data and resulting empirical models constitute a realistic basis for more complex numerical modelling. In addition, the GIS implementation constitutes a useful decision-support tool for real-time hazard mitigation. Copyright © 2008 John Wiley & Sons, Ltd.

    Description: A suitable index is proposed to evaluate the natural short–medium-term recovery capability of vegetation in burnt areas. The study area covers 2450 km2 in western Tuscany (Province of Pisa, Italy). This region is characterized by a typical Mediterranean climate and is subject to fire damage during the dry summer season. Damage is mitigated where a natural rapid regrowth of vegetation prevents soil erosion, supporting the return to a natural pre-fire state. The Vegetation Resilience After Fire (VRAF) index is based on the vegetation association, soil type and geology, and on morphological features such as slope and aspect. The results are proposed as georeferenced maps defining areas with different vegetation resilience for both high and medium burn severity. The VRAF maps estimate the natural ability of vegetation to recover after fire, and suggest where human intervention is required to improve this capability. The VRAF index was checked by monitoring vegetation regrowth after fire in three burnt areas over a five-year period using spectral signatures, the feature space and the NDVI derived from remote sensing data. This analysis indicates that the high values of the VRAF index correspond to a recovery period of almost three years. Field surveys were performed to further test the results. On the whole, the VRAF index is a good parameter for assessing the capability of vegetation to recover in northern Mediterranean areas.

    Description: The field of impact assessment is becoming increasingly important in a wide variety of applied disciplines. Some of the examples discussed in this book include air and noise pollution, terrestrial ecology, landscape, socio-economic impacts, traffic, hydrogeology and coastal waters. The authors come from the School of Planning at Oxford Brookes University. The book grew out of a project to evaluate the pros and cons of using expert systems (ES) and geographic information systems (GIS) to a task that had traditionally been carried out by experts without the benefit of GIS. The book caught my eye, because of my own interest in applying ES and GIS to mineral resource assessment. The accepted wisdom is that expert systems are useful and applicable in situations where a task can be carried out by an expert in a matter of a few hours. The task must be well defined, with well-established procedures for its solution. There should be agreement among experts on how the problem should be solved. The solution should not be based on "common sense", because this generally implies that the problem is too broad and diffuse to be encoded with rules. Although impact assessments have been around for some time, particularly in North America, it is a relatively new process and the definition and codification of assessments has not reached a generally accepted state. Furthermore, ...
