NEW INFORMATION TECHNOLOGY AND ITS CAPACITIES FOR MODELING OF GEOSYSTEMS

open access: yesГеодинамика и тектонофизика, 2015
Numerical solution of the Navier-Stokes equations for free and forced convection in solid and porous media is challenging as an evolution equation for pressure is lacking. An information technology is proposed on the basis of a new system of hydrodynamic

Lake formation, characteristics, and evolution in retroarc deposystems: A synthesis of the modern Andean orogen and its associated basins [PDF]

open access: yes, 2015
Lake deposystems are commonly associated with retroarc mountain belts in the geological record. These deposystems are poorly characterized in modern retroarcs, placing limits on our ability to interpret environmental signals from ancient deposits.

Integration of geological and geophysical data of different quality into the stochastic description of aquifers [PDF]

open access: yes, 2003
Many of the present problems in hydrogeology such as old waste disposal sites and the risk of the infiltration of contaminated riverwater concern the protection of groundwater. Solutions of qualitative and quantitative, site-specific groundwater problems

Ensemble Estimation of Historical Evapotranspiration for the Conterminous U.S.

open access: yesWater Resources Research, 2023
Evapotranspiration (ET) is the largest component of the water budget, accounting for the majority of the water available from precipitation. ET is challenging to quantify because of the uncertainties associated with the many ET equations currently in use,

Repair of Geological Models Based on Multiple Material Marching Cubes

open access: yesMathematics, 2021
In this paper, we present a multi-domain implicit surface reconstruction algorithm for geological modeling based on the labeling of voxel points. The improved algorithm sets a label for each voxel point to represent the type of its geological domain and ...

3D Modeling of Tunnel Engineering based on Geological Body [PDF]

open access: yes, 2012
3D geological modeling has involved the complexity of two aspects: data and models. 3D geological modeling of the tunnel project real environment needs to fully abstract data, the entity model needs to be decomposed into the geometric model, property ...
