Identifying Groundwater Recharge Sites through Environmental Stable Isotopes in an Alluvial Aquifer

Identifying Seasonal Groundwater Recharge Using Environmental Stable Isotopes

In this study, the stable isotope values of oxygen and hydrogen were used to identify the seasonal contribution ratios of precipitation to groundwater recharge in the Hualien River basin of eastern Taiwan. The differences and correlations of isotopes in various water bodies were examined to evaluate the groundwater recharge sources for the Hualian River basin and the interrelations between grou...

Identifying flood recharge and inter-aquifer connectivity using multiple isotopes in subtropical Australia

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 ...

Factors Affecting Phosphorous in Groundwater in an Alluvial Valley Aquifer: Implications for Best Management Practices

Many streams in the US are impaired because of high Soluble Reactive Phosphorous (SRP) contributions from agriculture. However, the drivers of ecological processes that lead to SRP loss in baseflow from groundwater are not sufficiently understood to design effective Best Management Practices (BMPs). In this paper, we examine how soil temperature and water table depth influence the SRP concentra...

Development of an Improved Fuzzy Approach to Model Potential Sites for Groundwater Artificial Recharge

Delineation of potential sites for groundwater artificial recharge is an important and challenging task. The purpose of this research is to develop a new data-driven fuzzy approach to model potential sites for groundwater artificial recharge. To achieve this end, the efficient criteria of a proper site for groundwater artificial recharge were first recognized and presented as a conceptual model...
