Nyenje, P.M. (author), Meijer, L.M.G. (author), Foppen, J.W. (author), Kulabako, R. (author), Uhlenbrook, S. (author)The transport of excessive phosphorus (P) discharged from unsewered informal settlements (slums) due to poor on-site sanitation is largely unknown. Hence, we investigated the processes governing P transport in a 28km2 slum-dominated catchment in Kampala, Uganda. During high runoff events and a period of base flow, we collected hourly water...journal article 2014

Hugenschmidt, C. (author), Ingwersen, J. (author), Sangchan, W. (author), Sukvanachaikul, Y. (author), Duffner, A. (author), Uhlenbrook, S. (author), Streck, T. (author)Land-use change in the mountainous parts of northern Thailand is reflected by an increased application of agrochemicals, which may be lost to surface and groundwater. The close relation between flow paths and contaminant transport within hydrological systems requires recognizing and understanding the dominant hydrological processes. To date, the...journal article 2014

(author)Evaporation is a key process in the water cycle with implications ranging, inter alia, from water management to weather forecast and climate change assessments. The estimation of continental evaporation fluxes is complex and typically relies on continental-scale hydrological models or land-surface models. However, it appears that most global or...journal article 2014

Munyaneza, O. (author), Mukubwa, A. (author), Maskey, S. (author), Wenninger, J.W. (author), Uhlenbrook, S. (author)In the last couple of years, different hydrological research projects were undertaken in the Migina catchment (243.2 km2), a tributary of the Kagera river in Southern Rwanda. These projects were aimed to understand hydrological processes of the catchment using analytical and experimental approaches and to build a pilot case whose experience can...journal article 2013

Mabrouk, M.B. (author), Jonoski, A. (author), Solomatine, D.P. (author), Uhlenbrook, S. (author)Serious environmental problems are emerging in the River Nile basin and its groundwater resources. Recent years have brought scientific evidence of climate change and development-induced environmental impacts globally as well as over Egypt. Some impacts are subtle, like decline of the Nile River water levels, others are dramatic like the...journal article 2013

Teklaeb, S. (author), Wenninger, J.W. (author), Uhlenbrook, S. (author)Measurements of the stable isotopes oxygen-18 (18O) and deuterium (2H) were carried out in two meso-scale catchments, Chemoga (358 km2) and Jedeb (296 km2) south of Lake Tana, Abay/Upper Blue Nile basin, Ethiopia. The region is of paramount importance for the water resources in the Nile basin. Stable isotope composition in precipitation, spring...journal article 2013

Hu, Y. (author), Maskey, S. (author), Uhlenbrook, S. (author)Using the Statistical DownScaling Model (SDSM) and the outputs from two global climate models, we investigate possible changes in mean and extreme temperature indices and their elevation dependency over the Yellow River source region for the two future periods 2046–2065 and 2081–2100 under the IPCC SRES A2, A1B and B1 emission scenarios. Changes...journal article 2013

(author)During the last decades, large-scale land use changes took place in the Hailiutu River catchment, a semi-arid area in northwest China. These changes had significant impacts on the water resources in the area. Insights into groundwater and surface water interactions and vegetation-water dependencies help to understand these impacts and formulate...journal article 2013

Euser, T. (author), Winsemius, H.C. (author), Hrachowitz, M. (author), Fenicia, F. (author), Uhlenbrook, S. (author), Savenije, H.H.G. (author)The use of flexible hydrological model structures for hypothesis testing requires an objective and diagnostic method to identify whether a rainfall-runoff model structure is suitable for a certain catchment. To determine if a model structure is realistic, i.e. if it captures the relevant runoff processes, both performance and consistency are...journal article 2013

(author)Adoption of soil conservation structures (SCS) has been low in high rainfall areas of Ethiopia mainly due to crop yield reduction, increased soil erosion following breaching of SCS, incompatibility with the tradition of cross plowing and water-logging behind SCS. A new type of conservation tillage (CT) involving contour plowing and the...journal article 2012

Sutanto, S.J. (author), Wenninger, J. (author), Coenders-Gerrits, A.M.J. (author), Uhlenbrook, S. (author)Knowledge of the water fluxes within the soil-vegetation-atmosphere system is crucial to improve water use efficiency in irrigated land. Many studies have tried to quantify these fluxes, but they encountered difficulties in quantifying the relative contribution of evaporation and transpiration. In this study, we compared three different methods...journal article 2012
