Inorganic and Organic Matter Urban Estuary Aarhus Harbour Estuary
2009/10/27
The nverine supply of suspended inorganic and organic sediment, its temporal
and spatial distribution and its exchange with the bay, were estimated for an
urban estuary (Aarhus Harbour Estuary, Denm...
Environmental Impacts of an Old Mine Tailings Deposit—Metal Adsorption by Particulate Matter
Environmental Impacts Old Mine Tailings Deposit Metal Adsorption
2009/10/27
The distribution of metals (aluminum, manganese, iron, copper, zinc, cadmium
and lead) between suspended particles and solution phase has been
studied by analysis of time series data in a stream rec...
The aim of this paper is to discuss the concept of potential evaporation and its
use in runoff models. The potential evaporation for forest is defined on basis of
estimated minimum canopy resistance...

Optical Properties Dissolved Organic Matter Finnish and Estonian Lakes
2009/10/22
The main objective of the present study is to test various methods for describing
the absorption spectra of coloured dissolved organic matter (CDOM) and to
determine the numerical values of some opt...
Landscape scale patterns in the character of natural organic matter in a Swedish boreal stream network
Landscape scale patterns natural organic matter stream network
2009/9/11
This paper defines landscape-scale patterns in the character of natural organic matter (NOM) and tests for relationships to catchment soil, vegetation and topography. The drainage network of a boreal ...

A system for sewage water treatment in a primary sedimentation pond was investigated using a reactor tank equipped with cylindrical reactors which had porous photocatalyst coated with TiO2 around an u...
Environmental factors affecting sedimentation of organic matter in Lake Takkobu, Kushiro Marsh
sediment organic matter
2009/4/1
In this study, the vertical profiles of C and N of sediment cores at 3 offshore stations were examined to better understand the environmental factors affecting the sedimentation of organic matter in t...
Hydrological characterisation of stalagmite dripwaters at Grotte de Villars, Dordogne, by the analysis of inorganic species and luminescent organic matter
stalagmite dripwaters luminescence
2009/3/24
Five stalagmite drip-waters in the Grotte de Villars, Dordogne, have been monitored from early 1997 to early 1998, for variations in discharge, major inorganic species and dissolved luminescent organ...
Nitrogen dynamics in the shallow groundwater of a riparian wetland zone of the Garonne, SW France: nitrate inputs, bacterial densities, organic matter supply and denitrification measurements
riparian zone nitrate removal spatial variations
2009/3/12
This study highlights the role of interactions between surface and sub-surface water of the riparian zone of a large river (the Garonne, SW France). Information is given about the role of surface wate...
