Abstract

Powerful software tools for the sequential and parallel simulation of water and solute transport in strongly heterogeneous porous media are developed based on an extensive discussion of the involved processes, as well as of numerical and implementation aspects.

The tools are applied to study problems involving parameter estimation in heterogeneous porous media, virtual soil systems and dynamic effects in heterogeneous soils. The excelent scalability of the numerical solver for both water as well as solute transport is investigated on BlueGene/P and /Q type supercomputers. As file transfer can be a bottleneck for large-scale simulations it is analysed carefully, obtaining near optimal data transfer rates with data sets of up to 17.5 Terabyte.
