Title: Modelling of Integrated Terrestrial and Aquatic systems
Abstract:
A river basin consists of aquatic and terrestrial ecosystems which
are tightly linked at multi-scale. Land
use changes due to the human activities and climate changes can pose serious
threats to the economic development and ecological sustainability at river
basins due to many factors, such as soil degradation, erosion, nutrient runoff,
flooding and draught. The physics and biogeochemistry of a river basin is complicated
as the biogeochemistry can result in a large response to hydrological processes.
In recent years, there has been a significant interest in understanding the
interaction between hydrological and biogeochemical processes in watersheds. In
this talk, I will summarize our recent work on modelling of integrated aquatic
and terrestrial ecosystems and face challenges and opportunities of watershed
modelling and management through coupling hydrological and biogeochemical
processes. We will use Soil and Water Assessment Tool (SWAT) as modelling
framework of watershed hydrology to quantify the impacts of climate change and
agricultural activities on water quality and water resources. Then, we will
integrate the biogeochemical models of agroecosystem into the SWAT model to
enhance capacities of the nitrification, denitrification and soil respiration
of the SWAT. Finally, we will apply the
integrated model into Athabasca river basin (ARB) to test the simulation of
water quality, N2O and CO2 emissions.
