Development of a Multivariate Regression Model for Soil Nitrate Nitrogen Content Prediction
linear regression multivariate statistics nitrogen NPS soil moisture spatial analysis visualization
2015/8/11
Although soil nitrate nitrogen (N) is a nutrient source for crop, it could be a potential nonpoint pollution source to the environment when its content remains high with an inappropriate management. S...

Although soil nitrate nitrogen (N) is a nutrient source for crop, it could be a potential nonpoint pollution source to the environment when its content remains high with an inappropriate management. S...
Exploiting the information content of hydrological ''outliers'' for goodness-of-fit testing
information content hydrological outliers goodness-of-fit testing
2010/12/22
Validation of probabilistic models based on goodness-of-fit tests is an essential step for the frequency analysis of extreme events. The outcome of standard testing techniques, however, is mainly dete...
THE CONTENT OF SOME NATURAL RADIOACTIVE ELEMENTS,ESPECIALLY 222Rn,IN SOME POTABLE WATERS IN SWEDEN
NATURAL RADIOACTIVE ELEMENTS Rn POTABLE WATERS IN SWEDEN
2009/10/29
The content of 222Rn in drinking water from 118 wells in southeastern
Sweden has been measured. The radiation dose from 222Rn is completely
dominant in comparison with the dose from other nuclides e...

Variations Water Content Unsaturated Zone Esker
2009/10/29
In this study the changes in water content in the unsaturated zone of a large
esker at T b s j o have been measured with a combined gammalneutron probe.
Periods of heavy rainfall and intense snow-me...
An Attempt to Reduce Nitrate Content in Ground Water Used for Municipal Water Supply by Changing Agricultural Practices
Nitrate Content Ground Water Water Supply Agricultural Practices
2009/10/28
The heavy use of manure and fertilizers has in some parts of Sweden resulted
in unacceptable concentrations of nitrate in ground water used for private and
municipal water supply. In Halland for exa...
Temperature and Salt Content Regimes in Three Shallow Ice-Covered lakes
Temperature Salt Content Regimes Ice-Covered lakes
2009/10/23
A field study on the temperature, salt content, and density regime in three shallow
ice-covered Karelian lakes is presented. The measurements show that the
heat content increases during the whole ic...
Calibration of Time Domain Reflectometry for Water Content in Peat Soil
Time Domain Reflectometry Water Content Peat Soil
2009/10/22
Since peat soil differs from mineral soil in several respects, mineral-soil calibration
functions for time domain reflectometry (TDR) are not necessarily applicable.
This paper evaluates a number of...
A MODEL FOR SITE SPECIFIC ESTIMATION OF THE AVAILABLE SOIL WATER CONTENT AND THE EVAPOTRANSPIRATION IN FOREST ECOSYSTEMS
water balance model EVAPOTRANSPIRATION FOREST ECOSYSTEMS
2009/10/12
A vertical water balance model is presented which calculates a set of different water balance parameters (evapotranspiration, interception, runoff and soil water content) for various land covers and i...
A fast TDR-inversion technique for the reconstruction of spatial soil moisture content
soil moisture TDR-inversion technique
2009/5/18
Spatial moisture distribution in natural soil or other material is a valuably information for many applications. Standard measurement techniques give only mean or punctual results. Therefore a new inv...
Application of a coupled microwave, energy and water transfer model to relate passive microwave emission from bare soils to near-surface water content and evaporation
microwave emission near-surface water
2009/3/25
The paper examines the stability of the relation between microwave emission from the soil and the average near-surface water content in the case of relatively smooth, bare soils, and then considers th...
