Accounting for instream lakes when interpolating stream water chemistry observations
geostatistics kriging stream water chemistry
2015/8/14
Direct monitoring of stream water chemistry is an increasingly important tool for securing stream water quality and assessing stream ecological functioning as it relates to overall ecosystem health. S...
Stream water quality associated with a livestock/poultry production operation in Southeastern Manitoba, Canada
coliform bacteria livestock nitrogen phosphorus stream water quality
2015/3/5
Water quality was examined in two parallel streams in southeastern Manitoba that enclosed a small hog and poultry operation with associated waste lagoons and manure spread fields. Nitrate-N (NN), moly...
Assessing the stream water quality dynamics in connection with land use in agricultural catchments of different scales
nitrates land use drinking water reservoir basins GIS
2015/2/4
The ecological status of many surface waters in the Czech Republic is poor, mainly due to still relatively high discharges of N substances especially from agriculture. High nitrate values in the strea...
Annual changes in the chemical composition of stream water in small catchments with different land-use (Carpathian Foothills, Poland)
river water chemistry water pollution nutrient compounds flow tendency
2015/2/4
The aim of the study was to identify the factors that influence annual changes in the chemical composition of stream waters. The research area was located in the marginal zone of the Carpathian Foothi...

Dissolved ion analyses of stream water from bamboo forests: Implication for enhancement of chemical weathering by bamboo
weathering rate plagioclase dissolved ions bamboo stream water
2017/4/11
Dissolved ion analyses of stream water were conducted monthly in three catchments of varying bamboo coverage of
similar geological setting for one year. We found that the concentration of dissolved S...
Differential Gene Expression in Zebrafish (Danio rerio) Following Exposure to Gaseous Diffusion Plant Effluent and Effluent Receiving Stream Water
Zebrafish gene expression metals ethoxyresorufin-o-deethylase
2010/12/22
Transcription of the biomarker enzyme cytochrome P4501A1 (CYP1A1) was significantly elevated in fish exposed to one plant effluent at both the 7 (16 fold) and 14 (10 fold) day time points. Sediment PC...
RELATIONSHIP BETWEEN STREAM WATER TEMPERATURE AND AMBIENT AIR TEMPERATURE
RELATIONSHIP STREAM WATER TEMPERATURE AMBIENT AIR TEMPERATURE
2009/10/29
The water temperature of streams and rivers is required for various
practical purposes and is frequently obtained by calculating the heat
budget. This method is tedious and yields rather inaccurate ...
Relationship between stream water quality and mean basin angle in mountainous drainage basins
mountainous area stream water quality mean basin slope
2009/7/14
The relationship between the stream water quality and mean basin slope was examined in the mountainous region of the Azusa River and Tama River basin. The ionic compositions of stream water are of Ca-...
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
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...
Stream water quality in acid sensitive UK upland areas：an example of potential water quality remediation based on groundwater manipulation
Stream water quality potential water quality groundwater manipulation
2009/6/8
The patterns of variation in water quality for an acidic stream draining plantation forest overlying acidic and acid sensitive gley soils with shale and slate bedrock changed following the introductio...
Characterization of spatial heterogeneity of groundwater-stream water interactions using multiple depth streambed temperature measurements at the reach scale
water fluxes heat conduction-advection streambed temperature
2009/5/15
Streambed temperatures can be easily, accurately and inexpensively measured at many locations. To characterize patterns of groundwater-stream water interaction with a high spatial resolution, we measu...
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...
Winter climate affects long-term trends in stream water nitrate in acid-sensitive catchments in southern Norway
Winter climate acid-sensitive catchments stream water nitrate
2009/4/29
Controls of stream water NO3 in mountainous and forested catchments are not thoroughly understood. Long-term trends in stream water NO3 are positive, neutral and negative, often apparently independent...
