- Abstract
- The hydrogeological features of karstic areas widely cause a low amount of runoff respect
to underground flow. This aspect is particularly relevant where the climate is arid
or semi-arid, as in the case of the low Murge Plateau (Murgia), located in Southern
Italy. The runoff is appreciable only as an effect of very high intensity rainfall for the
high hydraulic conductivity of karstic outcropping rocks. In these conditions the occurrence
of runoff is rare and is often associated to natural flooding of wide portion of
territory; this phenomenon is widespread emphasized by low gradient of ground surface
and by the presence of endorheic areas. The runoff frequency is so low the human
memory can be induced to underestimate the flooding risk and the consequences of
the utilisation of natural flooding areas. Agriculture and land use changes in the latest
decades have generally caused degradation of the karstic environment also due to the
practice of stone clearing and crushing, potentially favouring development of erosion,
desertification and modifying the water cycle. At the same time, other anthropogenic
activities such as hydraulics works, realisation of road and railway crossings, quarries
and the realisation of works and buildings in river and flooding areas have increased
the vulnerability along the drainage network. The contribution highlights the peculiarity
of flooding risk in the case of the selected karstic area, characterising the role of
human effects on the damages caused by more dramatic events. (literal)
