Comparisons of local infiltration-excess, overland flow and associated erosion behaviour with river behaviour at the catchment scale
overland flow erosion catchment scale
2015/1/4
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...

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 ...
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
2010/3/5
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 ...
APPLICATION OF GEOTECHNOLOGY TO WATERSHED SOIL CONSERVATION PLANNING AT THE FIELD SCALE
Soil conservation planning India mountainous watersheds
2009/10/12
Soil conservation planning in inaccessible mountainous watersheds is a very tedious and expensive job. Generally, in India most soil conservation programs are carried out with physical reconnaissance ...
THE EFFECT OF DIGITAL ELEVATION MODEL SCALE FACTOR ON SOIL EROSION STUDIES：CASE STUDY IN CAMERON HIGHLANDS, MALAYSIA
digital elevation model SOIL EROSION SCALE FACTOR
2009/10/12
The digital elevation model (DEM) is usually used to express a topographic surface in three dimensions and to imitate essential natural geography. The DEM is a model of the elevation surface, which is...
Applied tracers for the observation of subsurface stormflow at the hillslope scale
subsurface stormflow hillslope scale
2009/7/22
Rainfall-runoff response in temperate humid headwater catchments is mainly controlled by hydrological processes at the hillslope scale. Applied tracer experiments with fluorescent dye and salt tracers...
Scale dependence of the episodic hydrochemical response of nested catchments at Plynlimon
surface water chemistry nested catchments forested catchments
2009/6/8
Previous monitoring of the surface water chemistry of the forested catchments at Plynlimon has concentrated on weekly measurements. Hence, peak values and details of the rapid changes in chemistry occ...
“Blueprint”for the UP Modelling System for Large Scale Hydrology
UP Modelling System Large Scale Hydrology
2009/6/8
There are at least two needs to be met by the current research efforts on large scale hydrological modelling. The first is for practical conceptual land-surface hydrology schemes for use with existing...
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...
An application of a large scale conceptual hydrological model over the Elbe region
scale conceptual hydrological model Elbe region land surface scheme regional scale model
2009/5/26
This paper investigates the ability of the VIC-2L model coupled to a routing model to reproduce streamflow in the catchment of the lower Elbe River, Germany. The VIC-2L model, a hydrologically-based l...
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...
Uncertainty in soil physical data at river basin scale – a review
soil physical river basin scale
2009/5/15
For hydrological modelling studies at the river basin scale, decision makers need guidance in assessing the implications of uncertain data used by modellers as an input to modelling tools. Simulated ...
Estimating spatial mean root-zone soil moisture from point-scale observations
soil moisture point-scale spatial mean
2009/5/15
Root zone soil moisture is a key variable in many land surface hydrology models. Often, however, there is a mismatch in the spatial scales at which models simulate soil moisture and at which soil moi...
