Environmental characteristics of water quality in wetlands of the upper Takkobu River
water quality phosphorus
2009/4/1
To gather information about nutrient loadings in wetlands in the basin of eutrophied Lake Takkobu, we investigated water quality in the wetlands of the upper Takkobu River which suffers little or no h...
The role of wetlands in the hydrological cycle
wetlands hydrological functions flood reduction
2009/3/12
It is widely accepted that wetlands have a significant influence on the hydrological cycle. Wetlands have therefore become important elements in water management policy at national, regional and inter...
A standardised method for measuring in situ denitrification in shallow aquifers: numerical validation and measurements in riparian wetlands
denitrification shallowaquifer groundwater modelling
2009/3/12
A tracer test to examine in situ denitrification in shallow groundwater by a piezometer with a packer system used bromide as a tracer of dilution and acetylene (10%) to block the denitrification proce...
Evaporation characteristics of wetlands: experience from a wetgrassland and a reedbed using eddy correlation measurements
wetlands evaporation eddy correlation wet grassland
2009/3/11
Measurements of evaporation were made from July to November 1999 using the eddy correlation method on two wetland types – wet grassland and reedbeds – in south west England. The evaporative water use ...
Modelling CH4 emissions from arctic wetlands:effects of hydrological parameterization
CH4 emissions arctic wetlands effects hydrological parameterization
2010/1/15
This study compares the CH4 fluxes from two arctic wetland sites of different annual temperatures during 2004 to 2006. The PEATLAND-VU model was used to simulate the emissions. The CH4 module of PEATL...
Yangtze Estuary Tidal Wetlands Geographic Information System (YETWGIS) is a comprehensive software system for environmental management and decision of Yangtze estuary tidal wetlands. Based...
Abstract: In western Songnen Plain of China, the saline-alkaline degree of water bodies is high in salt marsh wetlands. Generally, pH is above 8.0, and the hydrochemical types belong to HC...

Characterization of suspended particles in Everglades wetlands
suspended particles Everglades wetlands
2014/4/22
We report the concentration, phosphorus (P) and nitrogen (N) content, and size and chemical fractionation of fine suspended particles (0.2-100 μm) and colloids (3 kilodalton [kDa]-0.1 μm) in the surfa...

An advanced approach for catchment delineation and water balance modelling within wetlands and floodplains
advanced approach catchment delineation water balance modelling wetlands floodplains
2010/1/25
Water balance of wetlands within lowland floodplains is strongly influenced by the temporally variable spatial extent of the interactions between groundwater and surface water. A robust algorithm will...
Role of wetlands and developed land use on dissolved organic nitrogen concentrations and DON/TDN in northeastern U.S. rivers and streams
Role of wetlands developed land dissolved organic nitrogen concentrations DON/TDN northeastern U.S. rivers and streams
2014/5/19
Previous studies have shown that watersheds with significant human development (i.e., urban and agricultural land use) generally have higher concentrations and fluxes of dissolved inorganic nitrogen (...
Seasonal bioavailability of dissolved organic carbon and nitrogen from pristine and polluted freshwater wetlands
Seasonal bioavailability pristine
2014/5/19
We examined the chemical composition and bioavailability of dissolved organic carbon (DOC) and nitrogen
(DON) from two pristine and two polluted cedar bog wetlands across three seasons. Pristine and ...
Interpreting stable isotopes from macroinvertebrate foodwebs in saline wetlands
Interpreting stable isotopes macroinvertebrate foodwebs saline wetlands
2014/5/26
We compared stable-isotope (δ13C and δ15N) and gut-content analyses of macroinvertebrate foodwebs in saline wetlands of the Laramie Basin, Wyoming, USA. Standard assumptions of stable-isotope fraction...
The effect of emergent vegetation on convective flushing in shallow wetlands: Scaling and experiments
emergent vegetation convective flushing shallow wetlands Scaling and experiments
2014/6/9
Many wetlands around the world are characterized by shallow water, dense vegetation in the littoral zones, no significant riverine inflow and minimal circulation. Recent research on the hydrodynamics ...
