| Zusammenfassung |
| This study presents the results of a historic reconstruction based upon
documentary sources of precipitation and floods during the last fifty years
of the 16th century in Central Spain. We used data from primary sources
contemporary to the events rather than compilations or secondary references.
These documents belong to the institutions that administered the study area
during the time period of interest and consist of municipal or monastic
minute books and administrative texts from properties belonging to the
nobility and royal family. Direct data that explicitly describe
meteorological or flood-related events are haphazardly distributed
throughout personal correspondence and various reports, and the sizes of
floods or precipitation events can also be deduced from indirect data. We
analysed the qualitative data by transforming them into numerical indices of
intensity/duration for precipitation and intensity/area for floods. We
differentiated three sets of years that presented different hydrological
patterns. The first period, from 1554 to 1575, exhibited regular
precipitation patterns associated with low-intensity floods. The second,
from 1576 to 1584, was characterised by low precipitation levels and few
floods. The third, from 1585 to 1599, showed intense precipitation with
large floods interspersed with long-lasting droughts. We interpret these
results in the context of the environmental and land-use patterns of the
time period studied, which coincided with a period of low temperatures. |
