| Outline of Final Research Achievements |
Global hydrological cycle is affected by human activities such as irrigation, dam reservoir operation, groundwater pumping and domestic and industrial water consumptions. This study incorporated the land surface model including the dynamic human impact modules such into an Atmospheric General Circulation Model. Results showed that amount of irrigation water demand was approximately 3133 km3/yr which is comparable to observation and previous approaches based on land surface offline simulations and statistical models. The incorporation of the human impact modules into the AGCM showed reasonable sensitivity for surface air temperature against an original AGCM without those modules, and this is comparable to a previous study which adopts the impact of irrigation activity by surface water and heat fluxes as lower boundary conditions for AGCM.
