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...
Comparisons of local infiltration-excess, overland flow and associated erosion behaviour with river behaviour at the catchment scale

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...
Using multi-model averaging to improve the reliability of catchment scale nitrogen predictions
multi-model averaging catchment scale nitrogen predictions
2014/12/17
Hydro-biogeochemical models are used to foresee the impact of mitigation measures on water quality. Usually, scenario-based studies rely on single model applications. This is done in spite of the wide...

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...
COMPARISON OF LOCAL INFILTRATION EXCESS, OVERLAND FLOW AND ASSOCIATED EROSION BEHAVIOR WITH RIVER BEHAVIOR AT THE CATCHMENT SCALE
Data Based Mechanistic OVERLAND FLOW LOCAL INFILTRATION EXCESS CATCHMENT SCALE

Modeling overland flow and erosion behavior is a very important scientific task today to prevent environmental impacts from human activities, as well as physical disasters such as floods and desertifi...
The role of spatial variability of soil moisture for modelling surface runoff generation at the small catchment scale
soil moisture surface runoff generation small catchment scale
2009/5/27
A Bayesian approach is described for dealing with the problem of infilling and generating stochastic flow sequences using rainfall data to guide the flow generation process, and including bounded (ce...
High-resolution phosphorus transfers at the catchment scale：the hidden importance of non-storm transfers
total phosphorus non-storm transfers catchment scale
2009/5/18
High-resolution measurements of total phosphorus (TP) concentrations in a stream draining a 5 km2 agricultural catchment (a sub-catchment of Lough Neagh in Northern Ireland) were made every 10 min by...
Soil moisture-runoff relation at the catchment scale as observed with coarse resolution microwave remote sensing
Soil moisture runoff relation catchment scale microwave remote sensing
2009/5/18
Microwave remote sensing offers emerging capabilities to monitor global hydrological processes. Instruments like the two dedicated soil moisture missions SMOS and HYDROS or the Advanced Scatterometer ...
Dynamical process upscaling for deriving catchment scale state variables and constitutive relations for meso-scale process models
catchment scale state variables meso-scale process models
2009/5/15
In this study we propose an uspcaling approach to derive time series of (a) REW scale state variables, and (b) effective REW scale soil hydraulic functions to test and parameterise models based on th...
Modelling the spatial variability of snow water equivalent at the catchment scale
snow water equivalent catchment scale
2009/5/13
The spatial distribution of snow water equivalent (SWE) is modelled as a two parameter gamma distribution. The parameters of the distribution are dynamical in that they are functions of the number of ...
Identifying runoff processes on the plot and catchment scale
runoff processes plot catchment scale
2009/5/7
Rainfall-runoff models that adequately represent the real hydrological processes and that do not have to be calibrated, are needed in hydrology. Such a model would require information about the runoff...
Thresholds, switches and hysteresis in hydrology from the pedon to the catchment scale：a non-linear systems theory
pedon catchment scale non-linear systems theory
2009/5/6
Hysteresis is a rate-independent non-linearity that is expressed through thresholds, switches, and branches. Exceedance of a threshold, or the occurrence of a turning point in the input, switches the ...
Generation of soil moisture patterns at the catchment scale by EOF interpolation
Empirical Orthogonal Function soil moisture
2009/4/28
Spatial patterns of soil moisture cannot be adequately characterized by direct measurement for most practical applications, so interpolation between observations is required. Interpolation of soil moi...
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...
