Understanding the processes controlling groundwater/surface-water interaction is essential for effective resource management and for protecting sensitive ecosystems. Through intensive monitoring of Chalk groundwater, shallow gravel groundwater and surface water in the River Lambourn, UK, using a combination of hydrochemical and hydrophysical techni...

An understanding of non-causal relationships between processes in the air, soil and water compartments of the environment is fundamental to sustainable integrated management. This paper provides an overview of the groundwater sub-compartment and asserts that it exhibits many characteristics of a complex system, especially in relation to a wide rang...

... With limited evidence, it is also impossible to achieve safe water and sanitation for urban and rural settlements (Guppy et al., 2018;Xiao et al., 2019;Yan et al., 2016). The groundwater aquifers exploited for these purposes occur in varied geological contexts (Bernard and Legchenko, 2003;Humphreys, 2001) and may range from simple to highly complex systems (Bloomfield et al., 2008;Chilton and Seiler, 2006). Alluvial aquifers are generally highly susceptible to contamination (Elangovan and Dharmendirakumar, 2013), and climate and hydrological variability (Andrés-Doménech et al., 2015;Kundzewicz et al., 2008), and particularly so because they are strongly dependent on rivers, whether perennial, seasonal or ephemeral, for recharge. ...
... However, surface water and groundwater are interconnected in a hydrological system (Guzm an et al. 2016;Kumar et al. 2009). Surface water bodies such as streams, lakes and reservoirs interact with groundwater in different ways and to different degrees, and such interactions are important for understanding basin hydrological processes (Allen et al. 2010). Therefore, it is particularly important to understand the relationship between surface water and groundwater for the integrated management of water resources in all water-deficient countries. ...
