Session 3B Multiprocesses Analysis, Modeling, and Product Application in Arid and Semiarid Regions

Monday, 7 January 2019: 2:00 PM-4:00 PM
North 126BC (Phoenix Convention Center - West and North Buildings)
Host: 33rd Conference on Hydrology

This session focuses on multiple processes analysis and simulation including but not limited to water, energy, carbon and nitrogen cycles in arid and semiarid regions, where water resources and ecosystems are vulnerable to climate change. To investigate the biogeophysical and biogeochemical cycles, the impact of reservoir regulation, irrigation, groundwater pumping, crop planting, fertilization, deforestation and afforestation, are tested, analyzed, and compared from offline land surface modeling and land-atmosphere coupled simulation to those based on reanalysis product, remote sensing, and in situ observations. Furthermore, accuracy, uncertainty, and error analysis for each individual terrestrial component is useful for physical processes understanding and data product application. The temporal scale covers from hourly to inter-decadal scales, and spatial scale covers from local, watershed, regional to global scales. In addition, applications of these data products and multi-scale hydroclimate modeling to drought/flood mechanism, monitoring and prediction, agricultural and water resources management, and long-term trend analysis are also welcome.
