  abstract = {{I}n arid central {A}ustralia, the similar to 1.14 {M} km(2) endorheic {L}ake {E}yre {B}asin ({LEB}) experiences sporadic floods, and contains saline shallow groundwater. {I}n this basin, where on-ground physical and chemical data are very sparse, new observations of major ion chemistry, stable isotopes (delta {H}-2, delta {O}-18, delta {C}-13), radiogenic isotopes ({H}-3, {C}-14) and remote sensing ({MODIS}) data were used to investigate groundwater recharge and salinisation processes in 2006-2007. {I}n {J}anuary 2007 there was a large and intense local rainfall event, followed by flooding to the normally dry {L}ake {E}yre resulting from heavy rainfall in the northern {LEB} that took similar to 2 months to arrive at {L}ake {E}yre. {G}roundwater chemistry from this study show no evidence of recharge from the floodwaters or the local rainfall; however this does not preclude the process. {L}ow transit times and low infiltrating volumes may mean that the recharge event has not yet been detected. {O}ver the longer term, the stable isotope chemistry indicates that groundwater is predominantly diffusely recharged during heavy local rainfall events (>100-150 mm/month), and radiogenic isotopes reflect an older shallow groundwater efficiently mixing with recent (decadal) recharge. {T}he high total dissolved solids ({TDS}) of regional shallow groundwater (up to 52.5 g/{L}) is intrinsically linked with these recharge processes; where infiltrating diffuse rainfall is evaporated, and heavy rainfall events transport saline pore water (saline due to evaporation in the unsaturated zone) to the groundwater system. {T}he high {TDS} of shallow groundwater beneath the dry {L}ake {E}yre bed (up to 322 g/{L}) is also controlled by evaporation. {H}owever, although evaporite minerals are prolific in the lake area, the non-conservative behaviour of {B}r in pore water limits analysis of the role of halite mineral dissolution and precipitation reactions controlling groundwater salinity. {E}vaporation-driven salinisation of shallow groundwater in arid central {A}ustralia is distinct from the transpiration-driven salinisation of groundwater in the {A}ustralian {M}urray {B}asin (located in a semi-arid climate), and results in relatively high groundwater salinity values compared with many other large arid zone endorheic basins across the world.},
