Application of multi-method approach to assess groundwater–surface water interactions, for catchment management

Abstract: Madlala, T. et al. (2018). Application of multi-method approach to assess groundwater-surface water interaction, for catchment management. AbstractGlobally, the dependence of river systems to delayed discharge of subsurface water to augment flows during dry seasons is well documented. Discharge of fresh subsurface water can dilute concentrated river flow quality during reduced flow. Observed and reported results on the Berg River's declining water quantity and quality are a concern to the regions socio-economi… Show more

“…This introduces further uncertainty in the runoff calculation. However, the discharge of GW into the rivers is considered important in arid and semi-arid areas, as it is part of the non-stationarity of the rain-runoff relationship, and it influences the quality of SW and the well-being of aquatic ecosystems [11,21,22].…”

“…If it is not the case, and the Peninsula Aquifer is contributing signi cantly to base ow, will it ever be possible to adequately represent a fractured aquifer system in distributed models like MIKE-SHE, in data scarce regions such as these? In a study of the Berg River, hydrograph separation analysis indicated that the Berg River is 38% dependent on subsurface water discharges annually (Madlala et al, 2018). This study estimated, on average, 5.4% of inter ow and base ow combined for all four catchments, with overland ow playing a more important role overall (46.2%).…”

“…This could lead to long-term groundwater depletion along with associated changes to the riverine environment [4,5]. River flows can also be affected by changes in stream-aquifer interactions in cases where they depend on groundwater discharge [6,7].…”
