EROSION PROFILE OF THE BLUE CLAY BEDROCK ALONG THE IONIAN COSAST OF THE BASILICATA REGION
No full textSea level, sea level changes and changes of the coastline are very important elements used in Engineering Geology for understanding many of the geomorphological and hydrogeological conditions or events.
Sea level is, for instance, the border condition of all coastal aquifers; in hydrogeology, stable sea levels have the same importance as that of marine terraces in geomorphology, because in the appropriate contexts they may mark well developed karst levels or overlapped dolomitization in carbonate rocks. Riverbed profiles also develop according to the final sea level; when it decreases, a strong erosion phase begins.
About 1500 stratigraphies of water wells or boreholes and geophysical logs have been analysed for hydrogeological purposes, with the aim of recognizing the bedrock of the coastal aquifer along the Ionic coastline of the Basilicata region. The data allowed us to draw a 3D surface of the bedrock, which was found to be eroded to a depth of about 100 m b.s.l. at the present mouth of the five main rivers of the region. Some profiles representing these results are shown.
This data may be important in evaluating the recent overall relative movement between the sea and the continent. This relative movement is either inexistent or very small, with reference to the past 18.000 years, if the appropriate max regressive sea level is adopted for this region

No full textA landslide inventory map, which shows the location of landslide phenomena and contains information about movement type, activity, etc., is a basic element for landslide susceptibility and risk assessment. For this reason, the evaluation of the quality, in terms of accuracy and
completeness, of landslide inventory maps is an important issue. In this paper, two landslide inventory maps are compared, in order to determine the corresponding quality, through a direct comparison, aimed to evaluate the degree of cartographic matching between the maps, and the determination of the statistical properties of landslide areas and the comparison between the frequency-area statistics of landslides contained in the two inventories. The two landslide inventory maps at 1:25,000 scale, used for these analyses, have been produced for Daunia region (Apulia, Southern Italy), by the Apulia River Basin Authority; the first, ‘archive inventory’’, by unifying the existing archive inventories; the second, ‘‘surveyed inventory’’, through aerial-photo interpretation and field investigations
