Abstract The African continent is rarely the focus of microplastics research, although ubiquity in environment undisputed and still increasing. Due to high production use plastic products partial lack recycling systems many parts continent, it can be assumed that microplastic particles are already present limnic terrestrial ecosystems. Few studies, mainly from South Africa Northern region, show a contamination with microplastics, especially marine environments. This study aims explore...
Semiarid regions are often affected by water scarcity and poor quality. Seasonal changes in precipitation drought events increase the pressure of use on bodies their pollution. In Central Northern Namibia, a high seasonal intra- inter-annual variability caused 5-year lasting period. semiarid region, ephemeral channels pans represent main source, besides institutionalized supply. No systematic analysis its quality has been conducted so far. The states surface waters at end dry season 2017...
Numerous ephemeral rivers and thousands of natural pans characterize the transboundary Iishana-System Cuvelai Basin between Namibia Angola. After rainy season, surface water stored in is often only affordable source for many people rural areas. High inter- intra-annual rainfall variations this semiarid environment provoke years extreme flood events long periods droughts. Thus, issue availability playing an increasingly important role one most densely populated fastest growing regions...
Abstract The aim of this study is the improvement TanDEM-X elevation model for future floodwater modeling by implementing surveyed road dams and use filter algorithms. Modern satellite systems like deliver high-resolution images with a high vertical horizontal accuracy. Nevertheless, regarding special usage they sometimes reach their limits in documenting important features that are smaller than grid size. Especially context 2D-hydrodynamic flood modelling, influence runoff processes, e.g....
Abstract The increasing pressure on freshwater systems due to intensive anthropogenic use is a big challenge in central-northern Namibia and its catchment areas, the Kunene Kavango Rivers, Cuvelai-Etosha Basin, that provide water for more than 1 million people. So far, there no comprehensive knowledge about ecological status only few quality. Therefore, it crucial learn state of ecosystem effects pollutants ensure safe these resources. surface waters three were sampled, bioassays applied...
Abstract The transboundary region of the Iishana system in western Cuvelai Basin, between southern Angola and northern Namibia, is frequently affected by floods at irregular intervals. As a result, predominantly rural, subsistence farming population has experienced crop failures, human, economic losses. To date, very little known about generation floods, flood concentration, stormwater drainage dynamics this region. In study, 2D‐hydrodynamic modeling was applied to reconstruct one latest...
