Tracer data demonstrate that waters in aquifers are often much older than the stream waters
that drain them. This contrast in water ages has lacked a general quantitative explanation …

The analysis of transit/residence time distributions (TTDs and RTDs) provides important
insights into the dynamics of stream‐water ages and subsurface mixing. These insights have …

Many studies underline the importance of groundwater assessment at the larger, ie global,
scale. The groundwater models used for these assessments are dedicated to the global …

ABSTRACT Simulation–optimization (S–O) is a well‐regarded method for solving
groundwater (GW) management problems. Although S–O has significantly improved the …

The granitic aquifer of the area under investigation serves as an important source of water
supply for the inhabitants. However, information about groundwater renewability and …

Groundwater is a vital source of water for humanity, with up to 50% of global drinking water
and 43% of irrigation water being derived from such sources. Quantitative assessment and …

The effective deep recharge to the Hutton Sandstone, a major confined aquifer of the Surat
Basin, Australia, has been quantified for the first time with the aid of environmental tracers. A …

Tritium dating requires a good understanding of the tritium and water inputs into hydrologic
systems, including their main trends due to latitudinal, seasonal and altitudinal effects …

This study investigates the water circulation using tritium measurements in local
precipitation, shallow dug wells and thermal springs of the Tural-Rajwadi area, which is one …

The radioactive isotope of hydrogen, known as tritium (3 H), is very often used as a dating
tool in hydrogeological studies, since it enters the water cycle as part of the water molecule …
