This research intends to analyse the architecture and the shape of the Sicilian qanats in their historical evolution in the Palermo’s plain, and in this context the conceptual schemes that characterize the various underground traditional water and distribution systems from the late Ancient age to early part of the 20th century are illustrated. Not...

Context 1
... richness in water resources of Palermo plain is represented by groundwater in the calcarenitic layers of its subsoil that contains a series of aquifers supplied directly by the rains that fall on the plain and from indirect contribution of underground water flows that overflow from the hydro-structures limestone of the mountains that surround it (Fig. 1). These constitute a huge reservoir, mainly of the karstic type, whose potentiality has been estimated to exceed one million cubic meters per year. The structure favourable of the mountainous geological formations, consisting of fissured dolomitic calcareous, is capable of draining and collecting the rainwaters of various ...

... for porosity, variable 10 -5 -10 -3 m/s; 2) A main aquifer formed by carbonate substratum rocks (limestone and dolomites) that constitute important hydro-structures in connection with the surrounding mountain ranges (Mounts of Palermo). They are permeable rocks for cracking and karst, with variable permeability values of 10 -1 -10 -3 m/s. On the Fig. 1 are indicated with the letters A, B, C, the main calcareous hydro-structures, primary hydric contribution of the qanat systems of Palermo. The carbonatic corps D and E (Mount Pellegrino and Mount Gallo) do not constitute active hydro-structures: they are sites of marine intrusion because of their geological structure and intense ...

... location of the list order numbers is shown on the hydro-structural map (Fig. 1). As you can see, so far, have been catalogued n.54 water systems, according to the types shown in Table 1, with the exception of the wells with blind galleries that have not been located, the ingruttati, the wells connected and the qanat are indicated and numbered 1. Out of a total of 54 inventoried systems of only 16, we have known ...
