Effects of Land Use on the Diffuse Load of Phosphorus and Nitrogen
Land Use Diffuse Load Phosphorus Nitrogen
2009/10/28
The diffuse load of phosphorus and nitrogen was studied in 23 small drainage
basins in different parts of Finland between 1965 and 1974. Total phosphorus
and total nitrogen concentrations were analy...
The Application of Radioactive Tracers for Determination of Bed-Load Transport in Alluvial Rivers
Radioactive Tracers Bed-Load Transport Alluvial Rivers
2009/10/28
Radioactive isotopes have been applied for determining the transport rate of
bed load in an alluvial river on the basis of: centroid velocity of the tracer
particles, size and material-transporting ...
River Flow with Excessive Suspended Sediment Load
River Flow Excessive Suspended Sediment Load
2009/10/27
River flows with high volume concentrations (20-50 %) of silty sediments generally
imply that the mixture has non-Newtonian properties. In this study, the
rheological behaviour of mixtures with soli...
Comparison of Sediment Rating Curves Developed on Load and on Concentration
Sediment Rating Curves Load Concentration
2009/10/23
A sediment rating curve developed as a lincar regression on logged values
which is back-transformed must be corrected for the bias introduced by the log
transformation. This article shows that the v...
A GREY SYSTEM MODEL FOR PREDICTING TREND CHANGE OF URBAN WASTE WATER LOAD
Grey System Prediction Model URBAN WASTE WATER LOAD TREND CHANGE
2009/10/19
The present paper introduces a Grey System Prediction Model (GSPM) by incorporating concepts of grey numbers within a grey differential equation framework as a means for predicting trends in urban was...
Glacial effects on discharge, sediment load and water chemistry from a subarctic river basin
glacier permafrost sediment load water balance tank model rating curve
2009/7/14
The subarctic Tanana River basin, Alaska, is occupied by ca. 5.6% glacierized region and the other discontinuous permafrost region. Time series of discharge, suspended sediment concentration (SSC) and...
Hydro-chemical characteristics of river water around Toyama bay and preliminary consideration of nitrate load toward the bay
NO3--N load Stable isotopic ratio Inorganic ion chemistry Tritium activity Toyama bay
2009/7/14
To understand hydro-chemical characteristics of river water and NO3--N load toward Toyama bay through the base flow. The hydrological field survey and analysis of inorganic ion chemistry, stable isoto...
Assessing the model performance of an integrated hydrological and biogeochemical model for discharge and nitrate load predictions
integrated hydrological biogeochemical model
2009/5/7
In this study, we evaluate the performance of the SWAT-N model, a modified version of the widely used SWAT version, for discharge and nitrate predictions at the mesoscale Dill catchment (Germany) for ...
Assessing emission reduction targets with dynamic models: deriving target load functions for use in integrated assessment
emission reduction critical load target load
2009/3/12
International agreements to reduce the emission of acidifying sulphur (S) and nitrogen (N) compounds have been negotiated on the basis of an understanding of the link between acidification related cha...
