2009/10/27
Isotope studies in Swedish till basins indicate that stream stormflow is normally
dominated by pre-event water. The rapid response of the groundwater outflow
to infiltration may be explained by a la...
Modeling nutrient in-stream processes at the watershed scale using Nutrient Spiralling metrics
biogeochemical models watershed applications fine-scale deterministic models

2009/7/22
One of the fundamental problems of using large-scale biogeochemical models is the uncertainty involved in aggregating the components of fine-scale deterministic models in watershed applications, and i...
Trends and seasonality in stream water chemistry in two moorland catchments of the Upper River Wye, Plynlimon
stream water chemistry Upper River Wye moorland catchments
font style='font-size:12px;'>
2009/6/8
Stream water chemistry in the Cyff and Gwy subcatchments within the headwaters of the River Wye has been monitored regularly since 1980. In the Gwy, which is a predominantly semi-natural grassland ca...
Towards benchmarking an in-stream water quality model
in-stream water quality model general quality assessment

2009/5/6
A method of model evaluation is presented which utilises a comparison with a benchmark model. The proposed benchmarking concept is one that can be applied to many hydrological models but, in this inst...
Incorporating landscape characteristics in a distance metric for interpolating between observations of stream water chemistry
stream water chemistry landscape characteristics

2009/5/6
Spatial patterns of water chemistry along stream networks can be quantified using synoptic or "snapshot" sampling. The basic idea is to sample stream water at many points over a relatively short perio...
Predicting long-term recovery of a strongly acidified stream using MAGIC and climate models (Litavka, Czech Republic)
acidified stream acid atmospheric deposition

2009/4/29
Two branches forming the headwaters of a stream in the Czech Republic were studied. Both streams have similar catchment characteristics and historical deposition; however one is rain-fed and strongly ...

2009/4/29
This study assesses the major chemical processes leading to acid extremes in a small, moorland stream in mid-Wales, UK, which has been monitored since 1979. Results suggest that base cation (mainly ca...
Using official map data on topography, wetlands and vegetation cover for prediction of stream water chemistry in boreal headwater catchments

2009/4/28
A large part of the spatial variation of stream water chemistry can be related to inputs from headwater streams. In order to understand and analyse the dominant processes taking place in small and het...

2009/4/28
Spatial dynamics of solute chemistry and natural abundance isotopes of nitrate (15N and 18O) were examined in seven locations and at the watershed outlet in 2001 and 2002 in a forest watershed in the ...
