| Zusammenfassung |
| Maps of areas with different vulnerability degrees are an integral part of
environmental protection and management policies. It is difficult to assess
the intrinsic vulnerability of karst areas since the stage and type of karst
structure development and its related underground discharge behaviour are
not easy to determine. Therefore, some improvements, which take into account
dolines, caves and superficial lineament arrangement, have been integrated
into the SINTACS R5 method and applied to a karst area of the south-eastern
Murge (Apulia, southern Italy). The proposed approach integrates the SINTACS
model giving more weight to morphological and structural data; in particular
the following parameters have been modified: depth to groundwater, effective
infiltration action, unsaturated zone attenuation capacity and
soil/overburden attenuation capacity. Effective hydrogeological and
impacting situations are also arranged using superficial lineaments and
karst density. In order to verify the reliability of the modified procedure,
a comparison is made with the original SINTACS R5 index evaluated in the
same area. The results of both SINTACS index maps are compared with karst
and structural features identified in the area and with groundwater nitrate
concentrations recorded in wells. The best fitting SINTACS map is then
overlaid by the layout of potential pollution centres providing a complete
map of the pollution risk in the area. |
