Pedotransfer Functions Bring New Life to Earth System Modeling

New Approaches in 3D Geomechanical Earth Modeling

In this paper two new approaches for building 3D Geomechanical Earth Model (GEM) were introduced. The first method is a hybrid of geostatistical estimators, Bayesian inference, Markov chain and Monte Carlo, which is called Model Based Geostatistics (MBG). It has utilized to achieve more accurate geomechanical model and condition the model and parameters of variogram. The second approach is the ...

New generation of hydraulic pedotransfer functions for Europe

A range of continental-scale soil datasets exists in Europe with different spatial representation and based on different principles. We developed comprehensive pedotransfer functions (PTFs) for applications principally on spatial datasets with continental coverage. The PTF development included the prediction of soil water retention at various matric potentials and prediction of parameters to ch...

Technical Note : The Modular Earth Submodel System ( MESSy ) – a new approach towards Earth System Modeling

Generally, the typical approach towards Earth System Modeling has been to couple existing models of different domains (land, ocean, atmosphere,. . .) offline, using output files of one model to provide input for the other. However, for a detailed study of the interactions and feedbacks between chemical, physical, and biological processes, 5 it is necessary to perform the coupling online. One st...

Estimating Hydraulic Conductivity Using Pedotransfer Functions

Multiscale Pedotransfer Functions for Soil Water Retention

Soil hydraulic properties are needed in globaland regionalscale circulation models for hydrologic and climate forecasting. They are also necessary in pointand nonpoint-source contaminant transport models. Prediction accuracy of these models is highly dependent on the quality of the model parameters. Collecting the required soil hydraulic parameters by direct measurement at any model grid scale ...
