Runoff Chemistry at a Mini-Catchment Watered with Unpolluted Precipitation
Runoff Chemistry Mini-Catchment Unpolluted Precipitation
2009/10/28
600 mm of artificial, "unpolluted" precipitation with a chemical composition
of assumed preindustrial quality ((HC] = 9 peql-I. ISO,] = 11 peql-') was
sprayed on a "mini-catchment" (98 m2) over a pe...
Sodium Mobility in a Mini-Catchment Studied with Radioactive Tracers and Artificial Precipitation
Sodium Mobility Mini-Catchment Radioactive Tracers Artificial Precipitation
2009/10/28
Seasalts in the precipitation may lead to a short-term acidification of the
runoff from natural catchments due to ion-exchange reactions. It was decided
to investigate this effect in the Storgama ar...
Equilibrium Speciation Models for Hg,Cd,and Pb in the Gulf of Bothnia and its Catchment Area
Equilibrium Speciation Models Gulf of Bothnia Catchment Area
2009/10/26
Equilibrium speciation models were established for Hg (11), Cd (11) and Pb (11)
in bog-, river- and sea water having a composition corresponding to that of the
Gulf of Bothnia (6%0 salinity). The ca...
Animal Communities in Icelandic Rivers in Relation to Catchment Characteristics and Water Chemistry
Animal Communities Icelandic Rivers Catchment Characteristics Water Chemistry
2009/10/23
Catchment areas of Icelandic rivers are mostly barren or with little vegetation
cover in the highlands, but with heathland and mire vegetation in the lowlands.
Chemical composition and nutrient avai...
Modeling Long-term Streamwater Chemistry in the Berg Catchment,Southwestern Sweden
Long-term Streamwater Chemistry Berg Catchment
2009/10/23
The geocheinical model MAGIC (5.01) was applied to the Berg - Pipbacken
Nedre catchment in southwestern Sweden for the period 1846-2020. The major
objective was to reconstruct historical acidificati...
The Influence of Polluted Water Flows on Hydrological and Hydrochemical Conditions of Purtse Catchment Rivers,NE Estonia
Polluted Water Flows Hydrological and Hydrochemical Conditions Purtse Catchment Rivers
2009/10/23
The correlation between natural (meteorological, hydrological), mining-technological, hydrogeological and geochemical factors in the oil shale mining region in the Purtse catchment area for the period...
Water flow pathways and the water balance within a head-water catchment containing a dambo：inferences drawn from hydrochemical investigations
Water flow pathways hydrochemical investigations water balance
2009/5/27
Dambos, seasonally saturated wetlands, are widespread in headwater catchments in sub-Saharan Africa. It is widely believed that they play an important role in regional hydrology but, despite research ...
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...
Water and nitrogen processes along a typical water flowpath and streamwater exports from a forested catchment and changes after clear-cutting：a modelling study
nitrogen water flowpath
2009/5/18
A two dimensional model, FEMMA, to describe water and nitrogen (N) fluxes within and from a forested first-order catchment (Kangasvaara in Eastern Finland) was constructed by linking the most signifi...
Hydrochemical heterogeneity in an upland catchment：further characterisation of the spatial, temporal and depth variations in soils, streams and groundwaters of the Plynlimon forested catchment, Wales
upland catchment Hydrochemical heterogeneity Wales
2009/5/18
The heterogeneous nature of upland hard-rock catchments in terms of geology, geomorphology, superficial deposits, soil type and land use gives rise to a range of hydrochemical characteristics in strea...

dissolved organic carbon particulate organic carbon organic carbon
2009/4/29
This study investigates for the first time the relative importance of dissolved organic carbon (DOC) and particulate organic carbon (POC) in the fluvial carbon flux from an actively eroding peatland c...
Modelling the effects of climate on long-term patterns of dissolved organic carbon concentrations in the surface waters of a boreal catchment
Dissolved organic carbon artificial neural networks
2009/4/29
Dissolved organic carbon concentrations ([DOC]) in surface waters are increasing in many regions of Europe and North America. These increases are likely driven by a combination of changing climate, r...
