Construction project of a dam to impound for irrigation purposes the VillafríaCreek in Santibáñez de la Peña Municipality (Palencia Province, Spain).


The project enclosed construction of a 343 m long loose materials dam.Maximum elevation above foundations reaches some 46.5 m, while the damcrest is 1,117.5 m. long. Crest width of the dike cross section is 8.00 m. wide with1.80H:1.00V outer slopes upstream and 1.60H:1.00V downstream. A 4.0 m wideintermediate berm is located in the downstream slope. The core wall top standsat a 1,116.90 elevation with a 1H:3V slopes in the upstream and downstreamslides, which rest on the waterproof substrate. Both downstream and upstreamof the core and abutting it, 3.00 m. thick granulated materials filters are arrangedwith a gradient similar to that of the mentioned core slopes. The downstreamfilter is actually the dam critical filter. To ensure outflow of water form both thedownstream filter, and leaks that might eventually develop due to thefoundations, the filter is extended downstream at the dam toe throughout thecreek bed width and all the way to the lowest zone. For this reason, a horizontaldrain 12 m. wide and 1.5 m. thick will be set at the toe protected by geotextile. Inthe upstream shell, 6 horizontal draining levels, 70 cm. large, are arranged. Thedownstream shell is protected by a 30 cm. thick topsoil layer. A 7 m. wide roadwill be available on the core wall top. The reservoir total impounding capacity(12 hm³) is achieved at the 1,114.50 m. elevation, which leaves thereby a 3 m.total freeboard below the dike crest.

Both the water intake works and undersluices are designed to enable the creekdiversion during the dam construction works. A rectangular section water intaketower is planned linked to the tunnel, used fot the creek diversion, during theworks first phase, while during the second phase, it is used to house theundersluices. Diameter of the water intake and undersluices ducts is 800 mm.Howell‐Bunger type regulating valves are used that discharge to a stilling bucketfor energy dissipation fitted with Bureau type stop valves. A Creager typespillway of fixed lip and front discharge is planned. It is located in a hill some 310m. away from the dam dike. The spillway crest is located at 1,114.50 m. elevtionand 49 m. long development.

Construction of a new Overhead and Buried Medium Voltage (MV) Power Line isplanned from the site specified for link up to the respective transformerssubstation line bay.
