“…This is particularly the case in alluvial aquifers where total recharge is often dominated by flood-related influxes (e.g. Workman and Serrano, 1999). In these alluvial systems, recharge rates are commonly elevated during floods, as a result of (1) the enhanced permeability of the creek bed during the flood, due to scouring of the clogging layer by high velocity flows (e.g.…”

Abstract. An understanding of hydrological processes is vital for the sustainable management of groundwater resources, especially in areas where an aquifer interacts with surface water systems or where aquifer interconnectivity occurs. This is particularly important in areas that are subjected to frequent drought/flood cycles, such as the Cressbrook Creek catchment in Southeast Queensland, Australia. In order to understand the hydrological response to flooding and to identify inter-aquifer connectivity, multiple isotopes (δ 2 H, δ 18 O, 87 Sr / 86 Sr, 3 H and 14 C) were used in this study in conjunction with a comprehensive hydrochemical assessment, based on data collected 6 months after severe flooding in 2011. The relatively depleted stable isotope signatures of the flood-generating rainfall (δ 2 H: −30.2 to −27.8 ‰, δ 18 O: −5.34 to −5.13 ‰ VSMOW) were evident in surface water samples (δ 2 H: −25.2 to −23.2 ‰, δ 18 O: −3.9 to −3.6 ‰ VSMOW), indicating that these extreme events were a major source of recharge to the dam in the catchment headwaters. Furthermore, stable isotopes confirmed that the flood generated significant recharge to the alluvium in the lower part of the catchment, particularly in areas where interactions between surface waters and groundwater were identified and where diffuse aquifer recharge is normally limited by a thick (approximately 10 m) and relatively impermeable unsaturated zone. However, in the upper parts of the catchment where recharge generally occurs more rapidly due to the dominance of coarse-grained sediments in the unsaturated zone, the stable isotope signature of groundwater resembles the longer-term average rainfall values (δ 2 H: −12.6, δ 18 O: −3.4 ‰ VSMOW), highlighting that recharge was sourced from smaller rainfall events that occurred subsequent to the flooding. Interactions between the bedrock aquifers and the alluvium were identified at several sites in the lower part of the catchment based on 87 Sr / 86 Sr ratios; this was also supported by the hydrochemical assessment, which included the modelling of evaporation trends and saturation indices. The integrated approach used in this study facilitated the identification of hydrological processes over different spatial and temporal scales, and the method can be applied to other complex geological settings with variable climatic conditions.

“…There are many works done on water movement in alluvium fan in the world (e.g., Mizutani and Oda, 1983;Li et al, 2008;Hidalgo and Cruz-Sanjulian, 2001;Mizutani et al, 2001;Chkirbene et al, 2009;Yuan et al, 2011;Vanderzalm et al, 2011;Tsuchihara et al, 2011). In this study, groundwaters and river waters in the Sho river fan were geochemically analyzed to determine the water flow and quality of groundwater in order to assess the potential use of the groundwater for Geo-HP.…”

“…Common features of arid land include fragile ecological environments, low and irregular precipitation, high temperatures, and high evaporation rates. Because of the scarcity and uncertainty of surface water supply, groundwater is a significant part of the total water resource in arid lands, and plays an important role as water supply for drinking and irrigation (Nativ et al 1997;Edmunds et al 2003;Vanderzalm et al 2011;Keesari et al 2014). Use of groundwater resources has increased dramatically in the past few years owing to drought, a rapidly growing worldwide economy, and increasing worldwide population.…”

“…Common methods in this respect include the chloride mass balance method, use of hydrogeochemical tracers (minor or trace metals), and determination of isotopic composition. These techniques can be used to identify sources of groundwater and estimate the contribution of each member (Vanderzalm et al 2011;Al-Charideh and Hasan 2013;Schulz et al 2013;Eissa et al 2014). In arid regions, where there is little precipitation but strong evaporation, hydrogeochemical indicators and stable isotopic groundwater compositions can be effectively employed to trace recharge sources and quantify relative evaporation (Nativ et al 1997;Vanderzalm et al 2011;Yangui et al 2011;Singh et al 2012;Ahmed et al 2013;Lapworth et al 2013).…”

Understanding sources of recharge and mechanisms for hydrogeochemical evolution of groundwater in the Shule River basin, an arid inland river basin in northwestern China, is essential for successful water resource management. Sources of water and associated groundwater recharge processes were investigated using hydrogeological, hydrogeochemical, and isotopic methods. The study area was divided into three parts: Changma, the Shule valley, and the Beishan area. The hydrogeochemical and isotopic analysis results show that groundwater in Changma mainly originated from precipitation in the Qilian Mountains. Lateral flow from Changma is the primary recharge mechanism, while direct recharge by infiltration of precipitation can be neglected in the Shule valley. Minerals within the aquifer material (e.g., halite, calcite, dolomite, and gypsum) dissolve into water that recharges the groundwater system. Therefore, strong linear relationships were found between Na ? and Cl -and between Ca 2?
