| Abstract: | It studies the characteristics of water movement in man made sand dune by the method of zero flux potential for the first time, based on making the observation of changes of water content, potential and temperature simultaneously by using neutron moisture meter, tensiometers and electric temperature gauge. It also explains the mechanism of water movement in the irreversible thermodynamic theory of thermal conduction and diffusion. That is very significant for utilizing water in sand dune, transforming desert and controlling disaster environments. |
