Coupled water and heat studies in subsurface environment

Abstract

The studies on coupled water-heat flow in subsurface environment are over viewed from four matrixes of steady-transient and heat-water as boundary conditions for subsurface system. The effects of groundwater flow on subsurface temperature and reconstructions of the heat or water boundary conditions including histories of surface temperature and groundwater recharge rate are shown. Three dimensional reconstruction of boundary conditions, effects of increase in subsurface temperature on the activities in subsurface biomass, and feedback process between surface warming and subsurface warming through ecosystem are presented as new directions of the studies for coupled water-heat transports in subsurface environment.
