The talks, as the papers in this issue indicate, were divided amongst the following topics: new advances in analytical developments, chemical structure of organic matter, processes
Paleonto- logical and organic geochemical results of this study have provided new evidence for marine transgressional events in the gigantic freshwater lake Songliao during the
When compared to the classical silica gel/alumina column chromatographic method, the neutral alumina procedure, recently validated for the isolation of organic nitrogen fractions
The use of line elements allows the inclusion of well bore storage eects, and also avoids the need of a second iteration step during the solution of the nonlinear ¯ow equation
We used a transient groundwater ¯ow model with particle tracking to show that mixing caused by ¯uctu- ations in recharge rate and lake levels causes vertical transverse dispersion.
However, in unsteady ¯ow, with signi®cant temporal variations in the velocity ®eld in both magni- tude and direction, the element-based algorithm pro- duces large tracking errors with
In this section we describe numerical experiments which we use to compare the Runge±Kutta characteristic methods developed in this paper (using both forward- and back-tracking)
The analytical solution (solid line) is compared with numerical solutions obtained by integrating the covariance function by rules of second-order (dashed line), third-order
