Study of the relationship between superficial water from lake and underground water, to constraint recharge mechanisms.

Study of the relationship between superficial water from lake and underground water, to constraint recharge mechanisms.

Survey of water level of Azigza lake and meteorological data.

Bathymetric map of Azigza lake.

High-resolution elevation model of Azigza watershed using the RTK-GPS combined with the assessment of topographic map scanned and a bathymetric map of the lake.

The dataset gives the variations of several climatic variables on the 0–10,000 year BP period by increment of 100 year. The variables are reconstructed using pollen data and an inverse vegetation model (BIOME4). The variables are expressed in term of anomalies according to their present reconstructions (0–100 years BP). The resolution of 100 years is certainly not reached for all the pollen diagrams used in the reconstruction. It is rather a maximum resolution. In reality, the time-series at that time step are rather smoothed and it should be unrealistic to interpret events with a length inferior to several centuries.
