Toward developing a high-resolution regional land surface eco-hydrological model for global change adaptation
Abstract
High-resolution regional earth system model (RESM) is targeted at providing essential information for adapting to the changing environment. However, most RESMs have deficiencies in representing synergistic effects of different types of human activities (e.g., reservoir regulation and irrigation, land use and land cover change, urbanization) on biogeophysical and biogeochemical processes. Here, we are developing a high-resolution regional land surface eco-hydrological model for a new generation of RESM over East Asia, and investigating the compound impacts of human interventions on water cycle and hydrological extremes. This presentation will introduce the progresses in: 1) the integration of high-resolution surface datasets including ESA CCI 300m land cover, GLASS 6km LAI data and Landsat 30m images for LUCC and urbanization modeling; 2) the development of a quasi-three-dimensional land surface hydrological model for explicitly describing the effects of lateral surface and subsurface flows on regional water and energy cycle, especially at high- or hyper-resolution; and 3) the incorporation of water resources management modules including reservoir regulation and irrigation. In addition, the applications of the high-resolution land surface modeling to attribute hydrological changes over headwaters region and downstream areas will also be presented.
