Einflüsse von Landnutzungsänderungen auf den Wasserhaushalt - Simulation von Landnutzungsszenarien im Hunte-Einzugsgebiet mit WaSiM-ETH
… hat. Es zeigt sich jedoch, dass ein Landnutzungswandel, wie er zwischen 1990 und 2000 stattgefunden hat, im Hunte-Einzugsgebiet nur zu minimalen Zunahmen im Abfluss führt. Die berechneten Szenarien bilden extreme Landnutzungsänderungen ab, die in der Summe aber ebenfalls nur einen …

Floods in the Niger River Basin in the face of global change
In the last decade, the number and dimensions of catastrophic flooding events in the Niger River Basin (NRB) have markedly increased. Despite the devastating impact of the floods on the population and the mainly agriculturally based economy of the riverine nations, awareness of the hazards in …

Spatial and temporal variability of the soil saturated hydraulic conductivity in gradients of disturbance
As land-cover conversion continues to expand into ever more remote areas in the humid tropics, montane rainforests are increasingly threatened. In the south Ecuadorian Andes, they are not only subject to man-made disturbances but also to naturally occurring landslides. I was interested in the …

Saturated hydraulic conductivity in the humid tropics : sources of variability, implications for monitoring and effects on near-surface hydrological flow paths
Large areas in the humid tropics are currently undergoing land-use change. The decrease of tropical rainforest, which is felled for land clearing and timber production, is countered by increasing areas of tree plantations and secondary forests. These changes are known to affect the regional water …

Urban land use detection and change using an enhanced monitoring system with remote sensing tools and GIS in the EUREGIO Meuse-Rhine area
The urban areas of Central Europe changed considerably during the past three decades. The spatiotemporal changes, induced by expansions and conversions, are monitored and registered in cadastral maps and statistical data. These national data-sets are indexed with specific criteria in every single …

Räumlich-strukturelle und zeitlich-dynamische Aspekte des Landnutzungswandels im Dreiländereck Belgien-Niederlande-Deutschland : eine Analyse mittels eines multitemporalen, multifaktoriellen und grenzübergreifenden Geographischen Informationssystems
The landscape of Central Europe has been subject to intensive changes since the beginning of the industrial revolution. The extent, the spatio-temporal structure, the causes, and the effects of this change were investigated for a 1730 km2 case study area situated in the country triangle between …
