Pande, S. (author), Uhlenbrook, Stefan (author)The challenge of sustainable development is enshrined in the ambitious 2030 Agenda for Sustainable Development of the United Nations. The 17 goals and its various targets are unique with water being one of the cross cutting themes. Taking examples of past water dependent societies in a comparative setting, this paper challenges the new field of...journal article 2020

Hassaballah, K.E.A. (author), Abbas Mohamedali, Y. (author), Omer, Amgad (author), Uhlenbrook, S. (author)Understanding the spatiotemporal dynamics of surface water in varied, remote and inaccessible isolated floodplain lakes is difficult. Seasonal inundation patterns of these isolated lakes can be misestimated in a hydrodynamic model due to the short time of connectivity. The seasonal and annual variability of the Dinder River flow has great...journal article 2020

Mabrouk, Marmar (author), Jonoski, Andreja (author), Essink, Gualbert H.P.Oude (author), Uhlenbrook, S. (author)The Nile Delta Aquifer (NDA) is threatened by salt water intrusion (SWI). This article demonstrates an approach for identifying critical salinity concentration zones using a three-dimensional (3D) variable-density groundwater flow model in the NDA. An innovative procedure is presented for the delineation of salinity concentration in 2010 by...journal article 2019

JIMENEZ RODRIGUEZ, C.D. (author), Coenders-Gerrits, Miriam (author), Uhlenbrook, S. (author), Wenninger, J.W. (author)The implementation of afforestation programs in arid environments in northern China had modified the natural vegetation patterns. This increases the evaporation flux; however, the influence of these new covers on the soil water conditions is poorly understood. This work aims to describe the effect of Willow bushes (Salix psammophila C. Wang...journal article 2019

Mabrouk, Marmar (author), Jonoski, Andreja (author), Oude Essink, Gualbert H.P. (author), Uhlenbrook, S. (author)As Egypt's population increases, the demand for fresh groundwater extraction will intensify. Consequently, the groundwater quality will deteriorate, including an increase in salinization. On the other hand, salinization caused by saltwater intrusion in the coastal Nile Delta Aquifer (NDA) is also threatening the groundwater resources. The aim...journal article 2018

Kok, D.D. (author), Pande, S. (author), van Lier, J.B. (author), Ortigara, Angela R.C. (author), Savenije, Hubert (author), Uhlenbrook, S. (author)Phosphorus is a nutrient necessary for the development of crops and is thus commonly applied as fertilizer to sustain agricultural production. It occurs naturally, in indefinite quantities of uncertain quality in phosphate rock formations, but also accumulates in urban and livestock wastewater wherefrom it is often lost as a pollutant....journal article 2018

Okello, Aline M.L.Saraiva (author), Masih, Ilyas (author), Uhlenbrook, S. (author), Jewitt, Graham P.W. (author), van der Zaag, P. (author)The variability of rainfall and climate, combined with land use and land cover changes, and variation in geology and soils makes it a difficult task to accurately describe the key hydrological processes in a catchment. With the aim to better understand the key hydrological processes and runoff generation mechanisms in the semi-arid meso-scale...journal article 2018

Ortigara, Angela Renata Cordeiro (author), Kay, Melvyn (author), Uhlenbrook, S. (author)In 2015, UN Member States adopted the 2030 Agenda for Sustainable Development, including Sustainable Development Goal 6 (SDG 6): "Ensure availability and sustainable management of water and sanitation for all". Commonly known as the 'water goal', SDG 6 went well beyond the limited focus on water supply and sanitation in the Millennium...journal article 2018

Digna, R.F.M.O. (author), Castro-Gama, Mario (author), van der Zaag, P. (author), Mohamed, Yasir A. (author), Corzo, Gerald (author), Uhlenbrook, S. (author)The Eastern Nile Basin is facing a number of transboundary issues, including water resources development, and the associated impacts. The Nile Basin, particularly the Eastern Nile Sub-basin, is considered as one of a few international river systems of potential conflicts between riparian countries. The Eastern Nile is characterized by the...journal article 2018

(author), van der Krogt, Wil (author), Corzo, Gerald (author)The Eastern Nile riparian countries are currently developing several reservoir projects to contribute to the needs for energy and food production in the region. In the absence of formal mechanisms for collaboration, the transboundary nature of the Eastern Nile basin makes water resources development challenging. The large seasonal and...journal article 2018

Kok, D.D. (author), Pande, S. (author), Ortigara, Angela Renata Cordeiro (author), Savenije, Hubert (author), Uhlenbrook, S. (author)Despite Africa controlling the vast majority of the global phosphate it also faces the greatest food shortages - partially due to a lack of access to the fertilizer market. A more accessible source of phosphorus comes from wastewater flows, which is currently lost through the discharge to open surface waters. Analysing the potential...journal article 2018

(author)rban catchments in sub-Saharan Africa (SSA) are increasingly becoming a major source of phosphorus (P) to downstream ecosystems. This is primarily due to large inputs of untreated wastewater to urban drainage channels, especially in informal settlements (or slums). However, the processes governing the fate of P in these catchments are largely...journal article 2014
