The summer water balance in a Danish oak forest was studied during a period
of 5 years. Interception reduces rainfall inside the forest by about 15%. Variations
of the saturated soil moisture amount...
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...
The Role of Soil Moisture in the Water-Balance of a Small-Clay Catchment,1967-75
Soil Moisture Water-Balance Small-Clay Catchment
2009/10/27
An eight year run of detailed soil moisture data has been incorporated into
simple water balance calculations in an attempt to estimate actual evapotranspiration.
The value of this data is shown whe...
A Comparison of Water Lag Times for Converging and Plane Surfaces
Water Lag Times Converging Plane Surfaces
2009/10/27
In order to examine the influence of the degree of convergence for converging
geometry on lag time, a comparison of surface water lag times for converging
and plane surfaces is made using the Overto...
Base Flow and Water Supply
Base Flow Water Supply
2009/10/27
The interaction between the base flow created by seepage through the unsaturated
zone in a region between two parallel rivers and the flow caused by the
gaining of water from wells positioned at arb...
Modelling Water Exchange and Transit Times in Till Basins Using Oxygen-18
Water Exchange Transit Times Till Basins Oxygen-18
2009/10/27
The application of hydrological models to data on conservative tracers can
yield information about transit times and storage volumes and may provide an
independent test of the model structure.In thi...
Modelling of Unsaturated Flow in Heterogeneous Soils Part 11:Stochastic Simulation of Water Flow over a Field
Unsaturated Flow Heterogeneous Soils Stochastic Simulation
2009/10/27
Modelling of soil moisture conditions in spatially variable fields is treated using
stochastic methods. Spatial variability of moisture content in a vegetation covered
field is partly caused by fiel...
Modelling of Unsaturated Flow in Heterogeneous Soils Part I:Deterministic Simulations of Water Flow in Soil Profiles
Unsaturated Flow Heterogeneous Soils Deterministic Simulations
2009/10/27
Water flow and solute transport in the upper soil layers are processes which are
of importance in many hydrological and agricultural applications. These processes
are occurring in a medium which has...
Spatial Variability of Soil Water and Evapotranspiration
Spatial Variability Soil Water Evapotranspiration
2009/10/27
Spatial variability in evapotranspiration from a crop covered field exposed to
homogeneous climatic conditions is partly caused by field variability in soil
physical properties and partly by field v...
Variations of 87Sr/86Sr in Water from Streams Discharging into the Bothnian Bay,Baltic Sea
Variations 87Sr/86Sr Ratio Bothnian Bay
2009/10/27
The 87Sr/86Sr ratio in 53 water samples were analysed, 26 from streams in
Sweden, 22 from streams in Finland and 5 from the Bothnian Bay itself. The
brackish seawater of the bay had the isotope rati...

Environmental Impacts Old Mine Tailings Deposit Metal Concentrations
2009/10/27
Variations in metal concentrations in a heavily polluted stream receiving acidic
leachates from an old mine tailings deposit are analysed from a hydrological
perspective. From an extensive data mate...
