Comparison of Fast Equation Solvers for Groundwater Flow Problemsder to save computer time equation solvers with high efficiency have to be chosen, especially when dealing with time-dependent and non-linear problems. Besides the direct Cholesky or frontal solvers, conjugate gradient techniques have become attractive in the last decade mainly due to improved preco

Modelling Flow and Transport Through Porous Media on Vector Computersrmance vector computers. Based mainly on primitive elements with linear integration law, the system consists of efficient and reliable algorithms working on data structures as a whole. The system has already been implemented on a CRAY X-MP and on a CDC-CYBER 205 and used in some practical studies co

Eulerian-Lagrangian Method for Solving Transport in Aquifersecomposed into advection along characteristic path lines and propagation of the residue at a fixed grid. The method was employed to simulate transport of a conservative pollutant in a hypothetical aquifer, subject to the equivalence of real conditions. Implementation was based on data involving para

The Random Walk Method in Pollutant Transport Simulation to avoid numerical dispersion. The random walk method offers a robust alternative if for reasons of calculational effort discretization requirements cannot be met. The method is discussed for the case of an ideal tracer starting out from the Ito-Fokker-Planck-equation. Features such as chemical rea

Nutrition and the Gastrointestinal System,st reviewed. These findings are attributed to large scale heterogeneity prevailing in natural formations. The spatial variability of hydraulic properties is regarded as random. The theory of transport by continuous, random, motions is presented and it is shown that it can model the field findings. T

Various aspects of field tracer test interpretation are then considered: automatic identification vs manual, comparison between two separate parallel layers and double porosity, the dependence of longitudinal and transverse macrodispersivities on travel time as a mean of accounting for he

Sara E. Monaco MD,Lisa A. Teot MDadient on the advective water flux and of enhanced thermal conduction by the processes of latent heat transfer with the vapor flow. The flow of the vapor is enhanced by its transfer through the water phase following a process of simultaneous evaporation and condensation at the air water interfaces.
