第34届国际湖沼学大会专题6：浮游生物动态对内陆水体甲烷通量和排放的影响（Effects of plankton dynamics on methane fluxes and emissions from inland waters）
第34届 湖沼学大会 浮游生物动态 内陆水体甲烷通量 排放影响
2018/1/20
Natural and man-made inland waters represent globally significant sites of methane production and emit annually about 100 Tg of this potent GHG to the atmosphere. On the other hand, a large fraction o...
Remotely sensed latent heat fluxes for model error diagnosis: a case study
latent heat fluxes model error diagnosis case study
2011/3/15
This study shows that remotely sensed ETact is useful in hydrological modelling for the procedure of model calibration and shows it potential to update soil moisture predictions. Comparison of modele...
Analysis of the impact of climate change on groundwater related hydrological fluxes: a multi-model approach including different downscaling methods
groundwater related hydrological fluxes multi-model approach
2011/1/7
Climate change related modifications in the spatio-temporal distribution of precipitation and evapotranspiration will have an impact on groundwater resources. This study presents a modelling approach ...
Ensemble modelling of nitrogen fluxes: data fusion for a Swedish meso-scale catchment
Ensemble modelling nitrogen fluxes data fusion
2010/12/22
Model predictions of biogeochemical fluxes at the landscape scale are highly uncertain, both with respect to stochastic (parameter) and structural uncertainty. In this study 5 different models (LASCAM...
The Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) for estimation of land surface heat fluxes
Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) estimation land surface heat fluxes
2010/4/7
A Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) is proposed for the estimation of surface heat fluxes using Thermal Infrared (TIR) data over sparsely vegetated surfaces. TSEBPS is ...

Fuzzy mapping momentum fluxes complex shear flows limited data
2009/12/4
This study is divided into three parts centred around modelling the complex turbulent fluxes across strong shear layers, such as exist between the channel and floodplain flow in an over bank flood flo...
The Role of Turbulent Heat Fluxes in the Energy Balance of High Alpine Snow Cover
Turbulent Heat Fluxes Energy Balance High Alpine Snow Cover
2009/10/26
Energy balance measurements over a seasonal snow cover were performed
near Davos, Switzerland at 2,540 m a.s.1. The energy fluxes were studied over
dry and melting snow covers. The beginning of snow...
Nitrogen and Phosphorus Fluxes from Finnish Agricultural Areas to the Baltic Sea
Nitrogen and Phosphorus Fluxes Agricultural Areas Baltic Sea
2009/10/26
Nutrient losses from small drainage basins were compared to the nutrient
fluxes in small coastal rivers in order to study the representativeness of the
Finnish monitoring network of small basins, es...
The Effect of River-Ice Break-Up on Suspended Sediment and Select Trace-Element Fluxes
River-Ice Break-Up Suspended Sediment Trace-Element Fluxes
2009/10/26
Ice break-up on northern rivers presents a unique research challenge because of
its dynamic nature and complexity of physical, chemical and biological processes.
Rapidly moving ice, ice jamming, flo...
Fluxes of Water and Energy from Three High Latitude Tundra Sites in Svalbard
Fluxes of Water Three High Latitude Tundra Sites Svalbard
2009/10/23
Measurements of the surface fluxes of radiation, heat and water vapour were
made at three tundra sites near N~-Alesund, Svalbard for the active seasons
(June to September) of 1995 and 1996. In 1995 ...
NITROUS OXIDE FLUXES FROM A CLAYPAN SOIL OVERLYING NITRATE-ENRICHED GLACIAL DRIFT
nitrous oxide glacial-drift aquifer claypan soil
2009/10/19
The closed chamber method was used to assess nitrous oxide (N2O) fluxes from corn (Zea mays, L.) fields during the 1995 growing season. The study area was characterized by a claypan soil overlying a n...
Averaging hydraulic head, pressure head, and gravitational head in subsurface hydrology, and implications for averaged fluxes, and hydraulic conductivity
hydraulic head pressure head gravitational head subsurface hydrology
2009/7/22
Current theories for water flow in porous media are valid for scales much smaller than those at which problem of public interest manifest themselves. This provides a drive for upscaled flow equations...
