The impacts of conifer harvesting on runoff water quality：a regional survey for Wales
runoff water quality Wales regional survey
2009/6/5
Major, minor and trace element chemistry of runoff at stormflow and baseflow from 67 catchments (2 to 5 ha in area) has been determined to investigate the effects of clear felling and replanting of co...
Use of deuterium to understand runoff generation in a headwater catchment containing a dambo
dambo runoff headwater catchment
2009/5/27
Dambos, seasonally saturated wetlands, are widespread in headwater catchments in southern Africa and play an important role in the regional hydrological cycle. However, the processes influencing runof...
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...
Rainfall-runoff modelling in a catchment with a complex groundwater flow system：application of the Representative Elementary Watershed (REW) approach
Representative Elementary Watershed Rainfall-runoff groundwater flow system
2009/5/18
Based on the Representative Elementary Watershed (REW) approach, the modelling tool REWASH (Representative Elementary WAterShed Hydrology) has been developed and applied to the Geer river basin. REWAS...
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 ...
Mapping mean and variance of runoff in a river basin
runoff river basin catchment area aggregation time
2009/5/13
The study presents an approach to represent the two first order moments of temporal runoff variability as a function of catchment area and aggregation time interval, and to map them in space. The prob...
Vectors of subsurface stormflow in a layered hillslope during runoff initiation
subsurface stormflow layered hillslope runoff initiation
2009/5/13
The focus is the experimental assessment of in-situ flow vectors in a hillslope soil. We selected a 100 m2 trenched hillslope study site. During prescribed sprinkling an obliquely installed TDR wave-g...
Distributed hydrological modelling of total dissolved phosphorus transport in an agricultural landscape, part I: distributed runoff generation
Soil Moisture Distribution and Routing distributed runoff generation
2009/5/13
Successful implementation of best management practices for reducing non-point source (NPS) pollution requires knowledge of the location of saturated areas that produce runoff. A physically-based, full...
Assessing winter storm flow generation by means of permeability of the lithology and dominating runoff production processes
winter storm flow coefficients permeability of the lithology runoff production processes
2009/5/13
In this study two approaches are used to predict winter storm flow coefficients in meso-scale basins (10 km² to 1000 km²) with a view to regionalization. The winter storm flow coefficient co...
Controls on runoff generation and scale-dependence in a distributed hydrologic model
Hydrologic response natural catchments
2009/5/13
Hydrologic response in natural catchments is controlled by a set of complex interactions between storm properties, basin characteristics and antecedent wetness conditions. This study investigates the ...
Formation of runoff at the hillslope scale during intense precipitation
hillslope scale intense precipitation
2009/5/7
On 60 m2 hillslope plots, at 18 mainly grassland locations in Switzerland rain was applied at rates of 50–100 mm/h for between 3 and 6 h. The generated flows were measured, including overland flow, ne...
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...
Transient catchment hydrology after wildfires in a Mediterranean basin: runoff, sediment and woody debris
Transient catchment hydrology Mediterranean basin woody debris
2009/5/6
The transient effect of forest fires on runoff, erosion and yield of woody biomass has been investigated by combining the experimental approach with mathematical models of hydrological processes. The ...
A new data assimilation approach for improving runoff prediction using remotely-sensed soil moisture retrievals
soil moisture retrievals sub-surface flow
2009/4/24
A number of recent studies have focused on enhancing runoff prediction via the assimilation of remotely-sensed surface soil moisture retrievals into a hydrologic model. The majority of these approache...
