Use of mean residence time and flowrate of thermal waters to evaluate the volume of reservoir water contributing to the natural discharge and the related geothermal reservoir volume. Application to Northern Thailand hot springs

摘要

Tritium-based mean residence time, tau(w), and flowrate, Q(w), of thermal waters from eleven different sites of Northern Thailand were used to evaluate the volume of reservoir waters contributing to the natural discharge, V-w, and the volume of the related geothermal reservoirs, Vres, assuming steady-state conditions and using simple relationships.
