Event Details

A special seminar on hydrology, environmental water science, isotope analysis and dating by Dr Makoto Kagabu, Faculty of Environmental Science, Nagasaki University.

Unfortunately this event has been cancelled for the foreseeable future.

Nagasaki is located at the western end of Japan, and has long prospered as a gateway to Western culture. However, for geographical location related reasons, in recent years there have been multiple environmental problems such as transboundary environmental pollution from the Asian continent. My laboratory aims to elucidate the flow mechanism of groundwater and spring water by water quality analysis and isotopic measurement techniques.In addition, we can also estimate the age of groundwater by using anthrophogenic environmental tracers (e.g. Chlorofluorocarbons, Sulfur hexafluoride, artificial sweeteners etc.).

The age of groundwater is an important parameter to determine whether our water use is sustainable or underground water is being'mined. Dating underground water is also important to establish if the water sources were recharged in pre-industrial times and the changes and challenges that have occurred in recent times.
