Wetland ecosystems make up approximately 6% of the Earth’s land surface (OECD, 1996). However, wetland habitats have been extensively altered over the years by commercial and residential development. As a result, some aquifers are literally dying due to habitat destruction, excessive drainage, flooding, or water quality degradation. In freshwater wetlands, hydrology plays a key role in vegetation dynamics. In turn, vegetation affects soil water balance through growth dynamics, transpiration and interception. The strong coupling between vegetation and surface/sub-surface water leads to important feedbacks between hydrology and ecosystem processes. Understanding better these main wetland components and processes would help guide efforts in the protection and restoration of wetlands.

This PhD research takes the Honghe National Nature Reserve (HNNR) in China as the research object and focuses on the simulation of wetland hydrodynamics with fundamental consideration to the physics of surface/sub-surface water flow processes. The results of this thesis will contribute to the following aspects:

Water Cycle and Climate

Water, food and energy security and environmental safety are key challenges to our societies. Better water resources management requires a fundamental understanding of the water cycle, water climate and water ecosystem interactions and impacts of human activities in the Earth’s climate system. Quantitative earth observation, hydrological modelling and data assimilation provide a powerful combination to quantify hydroclimatic variables for effectively addressing water management issues across the globe.
