The Birgi River Basin is located in the extreme western portion of Sicily and occupies a total area of about 336 km2. The shape of the area in question is sub-rectangular, with a NE-SW elongation direction and with a north-western appendage formed by the mouth of the Chinisia-Birgi river. Compared to the direction of extension, the area reaches its maximum width, equal to about 27 km, in the central portion; in the northern part, however, the width is significantly reduced, up to about 9 km, in the north-eastern portion. The basins bordering that of the Birgi River are the Lenzi River Basin to the North and the Màzaro River Basin to the South-East. To the North-East the Basin is delimited by the Territorial Area that separates it from the Lenzi Baiata River Basin while to the SW it is delimited by the Territorial Area that separates it from the Màzaro River Basin (052). The basin develops in the extreme north-western portion of Sicily, involving, from an administrative point of view, the territory of the province of Trapani and, in particular, the territories of eight municipalities (Buseto Palizzolo, Calatafimi, Erice, Marsala, Mazara del Vallo, Paceco, Salemi, Trapani). Of these municipalities, no inhabited center falls within the area but only the inhabited nuclei of Ballata (municipality of Erice), Fulgatore and Ummari (municipality of Trapani), Dara (municipality of Marsala). Inside the basin there is the artificial reservoir made up of Lake Rubino, built on the Cuddia stream by means of a barrier of loose material, about 30 m high, with a central sealing nucleus of clayey material. The Rubino reservoir, which has been in operation for several years, is located in the area upstream of the Birgi Basin, on the western side of Montagna Grande, and has a useful design capacity of 10.2 Mm3 of water, with the function of accumulation and modulation of natural outflows serving the vast underlying plain. The waters of the Birgi River are mainly used for irrigation, with requests for diversion concentrated in the upper part of its course.-------------------------- -------------------------------------------------- ---List of published data:1) Basin report in digital format (.pdf) 1.1) 50-51 REPORT.pdf 1.2) 20180521_050-051-052-053_Relation2) Cartography in digital format (.pdf) 2.A) Paper of instability in scale 1:10.000 (N.27 tables) 2.A.1) 10D_605080.pdf 2.A.2) 11D_606050.pdf 2.A.3) 12D_606060.pdf 2.A.4) 13D_605100.pdf 2 .A.5) 14D_605110.pdf 2.A.6) 15D_605120.pdf 2.A.7) 16D_606090.pdf 2.A.8) 17D_606100.pdf 2.A.9) 18D_605150.pdf 2.A.10) 19D_605160.pdf 2.A.11) 1D_593130.pdf 2.A.12) 20D_606130.pdf 2.A.13) 21D_606140.pdf 2.A.14) 22D_617030.pdf 2.A.15) 23D_617040.pdf 2.
