In the relation between urban development and the Viennese Danube different periods can be identified from the late 17th to the early 20th century. These periods were strongly intertwined with both the history of the river and the history of the city. Urban expansion into the floodplains is demonstrated in this paper by investigating the island Unterer Werd, next to the city centre. In the late...

During the past decades, large amounts of diffuse cadmium (Cd) and zinc (Zn) contaminated soil material have been deposited in the floodplains of the river Rhine in the Netherlands. As spatial information on soil quality is required at different scale levels covering the whole area, characterisation exclusively based on soil sampling and analysis is time-consuming and very expensive. A quicker ...

-The stochastic pyramid is introduced in landscape ecology in order to propose a spatial organization model of ecological units in river floodplains. It consists in articulating this parallel generator of random patterns with ecological processes. The stochastic pyramid, based on a hierarchy of seed structures, is used to make regions grow in order to obtain random patterns relating to an a pri...
