“…Some of them are Almonacid de la Cuba dam (Aguasvivas River, tributary of the Ebro River, Figure 1) (Arenillas et al, 1995; Beltrán & Viladés, 1994; I. Hereza, 1996; I. Hereza et al, 2000; J. I. Hereza et al, 1996); Muel dam (Huerva River, Ebro River basin, Figure 1) (Arenillas et al, 2006; Magallón et al, 2016; Uribe et al, 2010, 2012, 2013, 2016); Cornalbo, Proserpina, and Consuegra dams, in the Guadiana River basin (Arenillas et al, 1992, 2007; García‐Diego et al, 1983a, 1983b; Álvarez Martínez, 2007; Álvarez Martínez et al, 2002; Aranda & Sánchez Carcaboso, 2000; Aranda et al, 2006; Giles Pacheco, 2011; Martín Morales et al, 2002; Rodríguez Untoria, 2011); and Alcantarilla dam, in the Tajo River basin (Aranda & Sánchez Carcaboso, 2000; Aranda et al, 1997; Arenillas & Barahona, 2009a, 2009b; Barahona Oviedo et al, 2014; Barahona, 2018a, 2018b; Celestino, 1976; Sánchez Abal, 1977). For this reason, these are the most widely cited dams in the literature on civil constructions (Baba et al, 2018; Jansen, 1983; Mays, 2008, 2010; Schnitter, 1994; Smith, 1970, 1971; among others). These studies focus on construction and styles, and most of them lack rigorous dating, casting doubt on the Roman origin of some of them (Feijoo, 2005, 2006).…”
