Increasing concern over the effects of future climate change and the uncertainty of climatic and hydrological predictive models has encouraged many researchers to use documentary sources to determine climate variability at longer timescales. In this sense, research workers have used historical sources whereby different rivers and flood regions were related in order to detect climatic changes or anomalies since the medieval period (CAMUFFO and ENZI, 1992 and 1996; PICHARD, 1995; BARRIENDOS and RODRIGO, 2006). This research shows a broad flooding framework in terms of causality, magnitude, seasonality and frequency (BENITO et al., 2003). The shortage of instrumental records limits an adequate understanding of the relationships between climatology and flood (KNOX, 2000). Archival documents of site and weather patterns are more accurate than natural archives. The record discussed here covers a period of approximately 700 years and provides a safer basis for assessing the natural climate...
Flood frequency and seasonality of the Jucar and Turia Mediterranean rivers (Spain) during the “Little Ice Age”
Using a 700-year database, which includes the Little Ice Age period, flood frequency and the seasonality of 301 ordinary to extreme magnitude floods were probed for two Mediterranean rivers (Júcar and Turia). Of particular interest are the river surveys examining the causes of floods in the 16th and 17th centuries in the Júcar River and the “Fabrica de Murs i Valls” documents describing the flood processes in the Turia River since the end of the 16th century. Periods of higher flooding frequency were elucidated (1579‑1598, 1610‑1633, 1671‑1695, 1770‑1808, 1850‑1908, 1913‑1924 and 1947‑1958). Throughout some of these periods, a change in flood seasonality favouring non-autumnal events was observed. During the last centuries almost all major floods of the rivers Turia and Júcar (1590, 1632, 1776, 1779, 1805, 1864, 1897, 1923, 1949 and 1957) occurred during periods of high‑flooding frequency.
