Resumo

El Salt is an episodic waterfall located in the city of Alcoy (Spain), Alicante. The Barxell River Source, has calcium bicarbonate waters and an estimated flow rate of 17,000 m3 / day. It is a potential tufa generator, with an estimated generation capacity of up to 1,240 t / year. The tufa deposits located along Barxell River relates to the geomorphologic evolution of valley. Upstream the active waterfall it found a tufa river terrace T (+20 m). Downstream cascade, several types of tufa deposits links to two stages of geomorphologic evolution of the valley: a) The distal progradation tufa deposits related to a “non-effective to base-level change incision”, described as piedmont or progradation tufa build-ups T-1, T-2 and T-3; and b) The post "incisional base level change" tufa deposits, Font del Quinzet (T-4) tufa barrier, associated with back-lake sediments, and finally active tufa seeps on cliff (T-5).
