Small-Scale Planktonic Structure: Persistence and Trophic Consequences
Persistence Trophic Consequences
font style='font-size:12px;'>
2015/8/6
Most conventional sampling methods limit our ability to resolve planktonic distributions over vertical scales less than a few meters. Estimates of in situ biological rates also are limited by equipmen...
Lateral structure of uniform flow
Lateral structure uniform flow
font style='font-size:12px;'>
2009/12/4
The concept of uniform flow is traditionally associated with a cross-section-integrated description of channel flow. In some analyses of flow in wide channels, it may be appropriate to adopt a depth-i...
A 3D CFD model analysis of the hydraulics of an outfall structure at a power plant
3D CFD model analysis hydraulics outfall structure power plant
font style='font-size:12px;'>
2009/12/4
A practical application of a three-dimensional (3D) computational fluid dynamics (CFD) model to an outfall structure of a power plant is presented in this paper. The outfall structure, used for discha...

Correlation Structure and Time Scale of Simple Hydrologic Systems
Correlation Structure Time Scale Simple Hydrologic Systems
font style='font-size:12px;'>
2009/10/29
Correlation structure of river runoff is a complicated set of different persistence
phenomena in the watershed itself and in the meteorological input to the watershed.
Correlation functions and time...
Uncertainty in parameterisation and model structure affect simulation results in coupled ecohydrological models
parameterisation vegetation structure ecohydrological models
font style='font-size:12px;'>
2009/10/10
In this paper we develop and apply a conceptual ecohydrological model to investigate the effects of model structure and parameter uncertainty on the simulation of vegetation structure and hydrological...
The dominant role of structure for solute transport in soil：experimental evidence and modelling of structure and transport in a field experiment
soil field experiment solute transport
font style='font-size:12px;'>
2009/5/13
A classical transport experiment was performed in a field plot of 2.5 m2 using the dye tracer brilliant blue. The measured tracer distribution demonstrates the dominant role of the heterogeneous soil ...
Geostatistical investigation into the temporal evolution of spatial structure in a shallow water table
spatial structure shallow water table
font style='font-size:12px;'>
2009/5/13
Shallow water tables near-streams often lead to saturated, overland flow generating areas in catchments in humid climates. While these saturated areas are assumed to be principal biogeochemical hot-sp...
The Integrated Catchments model of Phosphorus dynamics (INCA-P), a new approach for multiple source assessment in heterogeneous river systems: model structure and equations
modelling water quality phosphorus
font style='font-size:12px;'>
2009/3/17
A new model has been developed for assessing the effects of multiple sources of phosphorus on the water quality and aquatic ecology in heterogeneous river systems. The Integrated Catchments model for ...
A nitrogen model for European catchments: INCA, new model structure and equations
modelling water quality nitrogen
font style='font-size:12px;'>
2009/3/17
A new version of the Integrated Nitrogen in Catchments model (INCA) was developed and tested using flow and streamwater nitrate concentration data collected from the River Kennet during 1998. INCA is ...
Assessment of spatial structure of groundwater quality variables based on the entropy theory
transinformation correlation spatial structure
font style='font-size:12px;'>
2009/3/12
Fundamental to the spatial sampling design of a groundwater quality monitoring network is the spatial structure of groundwater quality variables. The entropy theory presents an alternative approach to...
