The residence time of ground/ surface water is one of the most important parameters to understand hydrological and mass cycle processes in a watershed. However, residence time information of the water is still lacking to charactrize watersheds with steep topography underlain by young lithology, with a special concern of soil / gravel discharge, solute transport and hydro-geomorphological processes. Generally, we investigate the residence time of the water by applying radionuclides / noble gas tracers showing apparent age as 3H, 36Cl, CFCs and SF6, and/ or conservative tracers like stable isotopes, and need to understand a difference of residence time estimated by different type of tracers in various hydro-geological settings.
In this session, we compare the residence time of ground/ surface water and mass transport processes observed in various types of the watershed, and discuss issues to be solved and future perspectives on water age and mass cycle research topics.
