The evolution of the coastal aquifer of Belgium

In the unconfined aquifer below the coastal area of Belgium salt water Occurs under a fresh-water layer at depths that vary from 2 to more than 25 m. Radiocarbon dating of groundwater samples set the seawater encroachment in the deep parts of the aquifer back at least in the Sub boreal period. A working hypothesis concerning the evolution of the aquifer is formulated

Morphology of Würm Lateglacial and Holocene deposits in the Flemish valley (North Belgium)

The authors study the Würm Lateglacial evolution of the drainage, the morphology of the Lateglacial coversand ridges and their Holocene alterations. Special attention is drawn to sedimentological structures in relation to the reconstruction of the palaeo-environment and to the process of deposition. Palaeo-environmental and stratigraphical interpretations are based on lithological and sedimentological characteristics and successions. Palynological and 14C datings are being used but are not discussed here
