Savanna rangelands provide diverse communities across southern Africa with livestock and wildlife-based livelihoods, as well as extensive ecosystem services. Historical usage patterns, however, are increasingly challenged by widespread degradation. W...

Determining the source water and active root depth of woody plants using a deuterium tracer at a Savannah site in northern Stampriet Basin, Namibia (2023)
Journal Article
Uugulu, S., Wanke, H., & Koeniger, P. (2024). Determining the source water and active root depth of woody plants using a deuterium tracer at a Savannah site in northern Stampriet Basin, Namibia. Hydrogeology Journal, 32(1), 189-201. https://doi.org/10.1007/s10040-023-02747-x

Woody plants play a significant role in the global water cycle through water uptake by roots and evapotranspiration. A deuterium tracer was used to assess the active root depths for Salvia mellifera and Boscia albitrunca in the Ebenhaezer area (weste...

Vadose zone water stable isotope profiles for assessing groundwater recharge: Sensitivity to seasonal soil sampling (2023)
Journal Article
Boumaiza, L., Chesnaux, R., Drias, T., Stotler, R. L., Skrzypek, G., Gillon, M., …Stumpp, C. (2023). Vadose zone water stable isotope profiles for assessing groundwater recharge: Sensitivity to seasonal soil sampling. Journal of Hydrology, 626(Part A), Article 130291. https://doi.org/10.1016/j.jhydrol.2023.130291

Groundwater recharge is widely recognized as being the most important parameter for the sustainable management of water resources. In semiarid environments, groundwater recharge can be quantified using the piston displacement method (PDM). From a sin...

How are microplastics incorporated in fluvial sedimentary structures (2023)
Presentation / Conference
Beaumont, H., Ockelford, A., & Wanke, H. (2023, July). How are microplastics incorporated in fluvial sedimentary structures. Presented at International Conference on Fluvial Sedimentology

It's predicted there will be ~1.3 billion-tonnes of microplastics (MPs) in the environment by 2040, with rivers transporting 95% into the ocean; this is much higher than previously thought. MPs pose a threat to aquatic ecosystems and could become par... Read More about How are microplastics incorporated in fluvial sedimentary structures.
