general network of support diffusers.
S2 with the implantation of native species consists of a low-density shrub (lantana
camara) plantation established in a semi-shaded area by existing consolidated trees
(citrus aurantium, jacaranda mimosaefolia and celtis australis). S3 consists of a mixed
plantation of shrubby Mirato rose and trees (fraxinus angustifolia, prunus cerasifera).
Both are alternated with a mixed Kikuyo and English ray-grass pavement-plant at
50%, considering at the level of calculation of the garden coefficient Table 9, the
differentiation in three hydro-zones, which is defined as a delimited garden area
containing a series of plants with similar water needs, and therefore, an overall water
behaviour.
From the natural balance derived from the rainfall available in the area and the
water requirements of the group of plants that make up each scenario, the annual
irrigation requirements for each hydro-zone are deducted. The hydro-zone of S2 has
