Zusammenfassung |
The Mediterranean region is characterized by the presence of small catchments and intermittent water streams. Karst
springs play an important role on the definition of river dynamics either in the temporal or spatial aspects, consequently,
the intermittence of the river is explained by the karst springs regimes. This work aims at understanding the
relationships between the triggering of water flow on karst springs with climatic characteristics, by the example of the
Vène river karst springs (South-east Mediterranean coast of France). Climatic variables were calculated from rainfall
characteristics such as height, intensity, duration, and antecedent cumulated amounts. The analysis of the springs’
hydrographs allowed distinguishing rainfall events that could trigger the water flow on karst springs from rainfall events
that could not trigger them. The results showed that the water flow triggering at the main spring was mainly related to
cumulative rainfall amounts before the occurrence of the triggering rainfall event. This study contributed to a better
understanding of the karst springs responses to climatic factors. |
