Short summary
In near-stream aquifers, mixing between stream water and ambient groundwater can lead to dilution and the removal of substances that can be harmful to the water ecosystem at high concentrations. We used a numerical model to track the spatiotemporal evolution of different water sources and their mixing around a stream, which are rather difficult in the field. Results show that mixing mainly develops as narrow spots, varying In time and space, and is affected by magnitudes of discharge events.

Understanding the hydrologic cycle in semi-arid landscapes includes knowing the physical processes that govern where and why rivers flow and dry within a given catchment. To gain this understanding, we put together a conceptual model of what processes we think are important and then tested that model with numerical analysis. The results broadly confirmed our hypothesis that there are three distinct regions in our study catchment that contribute to streamflow generation in quite different ways.

Water and food security are vital for improving livelihoods in disadvantaged rural areas. Understanding the water cycle is central to the design of watershed development works intended to improve water security. Better farming practices can help improve food security. It is also vital for social constraints and equity to be considered. Finally, a participatory learning approach is useful for ensuring that watershed development work is effective in producing long-term improvement in livelihoods.

Short summary
Short summary
Catchment response can be influenced by man’s activities as well as natural forces like climate, and understanding how stream flow is affected by such activities is important in a changing world, particularly in developing countries. Data for the Bani River in Africa show a steady decrease in the groundwater component of stream flow. This paper shows that the decrease appears to be driven by increased water use in the catchment, and has resulted in the river ceasing to flow in the dry season.

Short summary
Improving management of water resources requires understanding of the natural and human components and drivers that influence the resources, and how these interact. Development of an integrated modelling process can be useful for gaining and sharing understanding of the impact of the interactions. Here we have developed such a modelling process for the Campaspe basin in northern Victoria, Australia. The model has been used to explore the impact of various scenarios on the water resources.
Improving management of water resources requires understanding of the natural and human...
