Hydrological dataset from the Green Roof Experimental Site in Genoa (Italy)

The Green Roof Experimental Site in Genoa (Italy) is essentially a flat roof on three different levels, with an overall surface area of approximately 1000 m2 covered with grass-herbaceous plants. In May 2007 a new substrate system was realized, on the central portion of this green roof, consisting of two halves with a total extension of about 350 m2. The new solution consists of a protection layer (300 g/m2 geotextile), a drainage layer (realized by lapillus for a depth of 15 cm), a filter layer (100 g/m2 geotextile) and a growing medium with mixed soil (lapillus, pumice, zeolite and 200 l/m3 of peat) for a depth of 20 cm. The Green Roof Experimental Site in Genoa is a modern technological system fully equipped with sensors for on-site meteorological, hygrometric and flow rate measurements.
