At the time, his father, a civil engineer, was the director of the recently established Douro River Basin Authority.

A keen interest in the Earth sciences led him to enroll simultaneously in a geology degree at the Universidad Complutense de Madrid, which he finished two years later. By 1963 he had already completed his two PhDs.He joined the Civil Engineer Corps, serving at the Eastern Pyrenees Basin Authority (1959)(1960), the Geological Survey of Public Works (1960)(1961)(1962)(1963)(1964)(1965)(1966)(1967)(1968)(1969)(1970)(1971)(1972) and the Center of Studies for Land and Environmental Management of the Ministry of Public Works (1980)(1981)(1982). The Ministry allowed him to further his professional specialization in France (1963), Germany (1964) and Israel (1965.Early on, his work delved into conventional hydraulics and engineering geology; however, the focus soon shifted to water planning and, thus, Dr. Llamas became a pioneer in the study of Spain's aquifers. His research emphasized the evaluation,
