Small-Scale Planktonic Structure: Persistence and Trophic Consequences
Persistence Trophic Consequences
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...
Comparisons of local infiltration-excess, overland flow and associated erosion behaviour with river behaviour at the catchment scale
Hydrologic modeling overland flow erosion catchment scale
2015/8/6
Modeling overland flow and erosional behaviour is a very important scientific task today to prevent environmental impacts from human activities as well as physical disasters such as floods and deserti...

Evapotranspiration modelling at large scale using near-real time MSG SEVIRI derived data
Evapotranspiration modelling using near-real MSG SEVIRI
2011/3/15
We present an evapotranspiration (ET) model developed in the framework of the EUMETSAT "Satellite Application Facility" (SAF) on Land Surface Analysis (LSA). The model is a simplified Soil-Vegetation-...

Topographic effects on solar radiation distribution in mountainous watersheds and their influence on reference evapotranspiration estimates at watershed scale
solar radiation distribution mountainous watersheds
2010/12/22
Distributed energy and water balance models require time-series surfaces of the climatological variables involved in hydrological processes. Among them, solar radiation constitutes a key variable to ...
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...
Spatial uncertainty assessment in modelling reference evapotranspiration at regional scale
evapotranspiration regional scale
2010/12/22
Evapotranspiration is one of the major components of the water balance and has been identified as a key factor in hydrological modelling. For this reason, several methods have been developed to calcul...
Observing and modeling the catchment scale water cycle
Observing modeling catchment scale water cycle
2013/9/2
The hydrology community has a long history of using experimental catchments as a test bed for new observation methods and new models. What distinguishes catchment hydrology from neighboring discipline...
Modelling field scale water partitioning using on-site observations in sub-Saharan rainfed agriculture
field scale water partitioning on-site observations sub-Saharan rainfed agriculture
2010/4/7
Smallholder rainfed farming systems generally realise sub-optimal crop yields which are largely attributed to dry spell occurrences during crop growth stages. However, through the introduction of appr...
Parameterization of a coupled CO2 and H2O gas exchange model at the leaf scale of Populus euphratica
Parameterization coupled CO2 and H2O gas exchange model leaf scale Populus euphratica
2010/4/7
The following two models were combined to simultaneously predict CO2 and H2O gas exchange at the leaf scale of Populus euphratica: a Farquhar et al. type biochemical sub-model of photosynthesis (Farqu...
Implementing small scale processes at the soil-plant interface – the role of root architectures for calculating root water uptake profiles
small scale processes soil-plant interface root architectures root water uptake profiles
2010/2/20
In this paper, we present a stand alone root water uptake model called aRoot, which calculates the sink term for any bulk soil water flow model taking into account water flow within and around a root ...

In this paper, we present a stand alone root water uptake model called aRoot, which calculates the sink term for any bulk soil water flow model taking into account water flow within and around a root ...
Chaos in rainfall:variability,temporal scale and zeros
Chaos in rainfall variability temporal scale zeros
2009/12/4
A recent study on rainfall observed at the Leaf River basin reports that the presence of a large number of zeros in the data significantly underestimates the correlation dimension. The present study a...
Large-scale instability of a generalized turbulent Kolmogorov flow
Large-scale instability generalized turbulent Kolmogorov flow
2009/10/30
We present an analytical study of the large scale instability of a generalized turbulent Kolmogorov flow, i.e. a periodic shear flow where the molecular viscosity has been substituted by an eddy visco...
