Coupled biogeochemical cycles in riparian zones with contrasting hydrogeomorphic characteristics in the US Midwest
Hydrology Biogeochemistry Riparian zones
2015/1/16
Numerous studies have investigated the fate of pollutants in riparian buffers, but few studies have focused on the control of multiple contaminants simultaneously in riparian zones. To better understa...
The impact of glaciation and climate change on biogeochemical cycling and landscape development
geochemistry phosphorus sediment glacial lake
2015/1/16
Lake cores from Dry Lake, California and Crystal Lake, Illinois were analyzed to identify climate variability and characterize landscape response to glacial/deglacial climate transitions.

Atmospheric inputs of phosphorus and nitrogen to the southwest Mediterranean region: Biogeochemical responses of high mountain lakes
Biogeochemical responses Atmospheric inputs
2014/5/4
We quantified dry and wet deposition of dust, nitrogen, and phosphorus over the southwest Mediterranean region (Sierra Nevada, Spain) and assessed its effects on the nutrient status and the chlorophyl...
Simulation of a Biogeochemical Model in Different Lakes
Simulation Biogeochemical Model Different Lakes
2009/10/22
Eutrophication, caused by nutrients leached from soil and emitted from point
sources, is a well-known problem in many Swedish lakes. There are several
countermeasures that can be used to reduce eutr...
Assessing the model performance of an integrated hydrological and biogeochemical model for discharge and nitrate load predictions
integrated hydrological biogeochemical model
2009/5/7
In this study, we evaluate the performance of the SWAT-N model, a modified version of the widely used SWAT version, for discharge and nitrate predictions at the mesoscale Dill catchment (Germany) for ...
Lacustrine wetland in an agricultural catchment：nitrogen removal and related biogeochemical processes
Lacustrine wetland agricultural catchment biogeochemical processes
2009/4/29
The role of specific catchment areas, such as the soil-river or lake interfaces, in removing or buffering the flux of N from terrestrial to aquatic ecosystems is globally recognized but the extreme va...
Biogeochemical model coupled with hydrodynamic model in lake environment
lake ecosystem biogeochemical model hydrodynamic model
2009/4/2
To study the environmental impact of activities such as forest logging, especially the impact on a lake ecosystem, it is necessary to develop a combined biogeochemical and hydrodynamic model. Here the...
Necessity to consider hydrological controls of biogeochemical cycling when developing a catchment-scale ecosystem model
hydrological controls catchment-scale ecosystem model biogeochemical cyclin
2009/4/2
In order to model the stream water chemistry in a forest catchment, the model should include functions describing both the biogeochemical cycle and the hydrological pathways as the transportation syst...
Biogeochemical model in forest ecosystem：Application and problem of PnET model
nutrient cycling stream chemistry simulation model process-based model carbon and nitrogen dynamics
2009/4/2
Biogeochemical processes are closely related to ecosystem functioning and the change in stream chemistry against various environmental changes. A process-based model that replicates the interaction be...
Physical and biogeochemical controls of microaggregate dynamics in a tidally affected coastal ecosystem
Physical biogeochemical controls
2014/5/4
Tidal flat ecosystems exhibit pronounced tidal currents that cause high loads of suspended matter (SPM) and intense sedimentation. To identify systematic patterns of tidal SPM dynamics and the signifi...
