| The mangroves of Senegal are limited to the inlet of the Casamance - a river with very low discharge - and to the Sine-Saloum. The mineralogical and geochemical analysis of sediments (derived from 30 deep bore-holes) shows the thickness of the mangrove substrate, which overlies the continental terminal formation. Kaolinite and smectite account for over 90% of the clay fraction. The former is derived from the continental terminal whereas the latter is of marine origin. The chemical composition of the mangrove sediments is remarkably stable and clays play an overwhelming role in the preservation of organic matter and pyrite. Since 1968, a drought in Senegal has caused an important increase in the salinity levels of streams and water-tables; a considerable... |

| A pluridisciplinary study was carried out in the south-eastern part of Kalimantan (Indonesia) in a deltaic area close to Banjarmasin town. Upstream from Banjarmasin, Barito river divides into two branches, one of which meets the Kapuas river slightly further to the west, to form the Kapuas Murung estuary. This programme is designed to increase knowledge about the physical and sedimentological processes, physical and chemical properties of the soils, and hydrological and chemical parameters of the Barito estuary. Barito estuary was chosen for two main reasons. First, it constitutes an important waterway for the region, on which Banjarmasin harbour is located; second, the management of the sparsely occupied coastal areas is becoming a priority. The... |
