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...
All scientific work performed so far to find the causality of the acidification of
many Norwegian open waters, have - considerably - increased our knowledge
about precipitation and soil water chemis...
This paper presents a review of groundwater models capable of simulating solute transport
(i.e. advection-dispersion) and equilibrium chemistry processes.
Introductory, basic model components are di...
Equilibrium Speciation Models for Hg,Cd,and Pb in the Gulf of Bothnia and its Catchment Area
Equilibrium Speciation Models Gulf of Bothnia Catchment Area
2009/10/26
Equilibrium speciation models were established for Hg (11), Cd (11) and Pb (11)
in bog-, river- and sea water having a composition corresponding to that of the
Gulf of Bothnia (6%0 salinity). The ca...
Cumulative Semivariogram Models of Trace Elements from Springs in Saudi Arabia
Cumulative Semivariogram Models Trace Elements Saudi Arabia
2009/10/26
Trace elements are rarely distributed in earth's crust and they are invariably in
low concentrations. Due to this low concentration they are not analyzed by
conventional hydrochemical methods but by...
Comparison of simulated forest soil response to acid deposition reduction with two models of differing complexity
forest soil \acid deposition reduction
2009/6/5
Great effort has been dedicated to developing soil acidification models for use on different scales. This paper focuses on the changes in model performance of a site scale soil acidification model (NU...
Predicting long-term recovery of a strongly acidified stream using MAGIC and climate models (Litavka, Czech Republic)
acidified stream acid atmospheric deposition
2009/4/29
Two branches forming the headwaters of a stream in the Czech Republic were studied. Both streams have similar catchment characteristics and historical deposition; however one is rain-fed and strongly ...
