Liquid-Vapor-Air Flow in the Frozen Soil

Posted by Yijian Zeng in the category Case Studies

Accurate representing freeze-thaw (FT) process is of great importance in cold region hydrology and climate studies. With the STEMMUS-FT model (Simultaneous Transfer of Energy, Mass and Momentum in Unsaturated Soil), we investigated the coupled water and heat transfer in the… Read more

Case Study 1: The effect of different evapotranspiration methods on portraying soil water dynamics and ET partitioning in a semi-arid environment in Northwest China Different methods for assessing evapotranspiration (ET) can significantly affect the performance of land surface models… Read more

Module development

Posted by Yijian Zeng in the category Module Development

The STEMMUS was designed as such that different modules can be “plug-in” easily. Currently, the freezing-thawing module is under development. The further development will be carried out to include biogeochemical cycle, and interactions with groundwater flow. Figure… Read more
