Estimation of Aquifer Transmissivity using Kriging, Artificial Neural Network, and Neuro-Fuzzy models
Neuro-Fuzzy interpolation groundwater
2015/1/6
In interpolation of groundwater properties such as transmissivity, due to the unknown distributed values of the variables and heterogenity, the best and the unbiased aspects are frequently difficult t...
Seasonal Variations of Oxygen-18 in Soil Moisture and Estimation of Recharge in Esker and Moraine Formations
Seasonal Variations Oxygen-18 Soil Moisture Moraine Formations
2009/10/28
The use of Oxygen-18 as a natural tracer of soil moisture and estimation of
recharge in different types of soils is presented and discussed. The 8 values ~f
180 in summer and winter precipitation in...
Estimation of Canopy Reservoir Capacity and Oxygen-18 Fractionation in Throughfall in a Pine Forest
Canopy Reservoir Capacity Oxygen-18 Fractionation Pine Forest
2009/10/27
Amount and oxygen-18 content of rainfall and throughfall have been monitored
in a pine forest in Uppsala during summer 1983. It is found that the free
throughfall coefficient, C, the canopy reservoi...
Modelling the Effects of Acid Deposition:Estimation of Long-Term Water Quality Responses in Forested Catchments in Finland
Acid Deposition Long-Term Water Quality Responses Forested Catchments
2009/10/27
A modelling study has been undertaken to investigate long-term changes in
surface water quality in two contrasting forested catchments; Yli-Knuutila, with
high concentrations of base cations and sul...
Estimation of Parameter Uncertainty in the HBV Model
Estimation of Parameter Uncertainty HBV Model
2009/10/23
Usually the HBV model is calibrated by seeking one optimal parameter set that
represents the catchment. From experience we know, however, that it is hardly
poss~ble to find an unique parameter set. ...
Estimation and Scaling of the Near-Saturated Hydraulic Conductivity
Estimation and Scaling Near-Saturated Hydraulic Conductivity
2009/10/23
The hydraulic conductivity in structured soils is known to increase drastically
when approaching saturation. Tension infiltration allows in situ infiltration of
water at predetermined matric potenti...
