Provided a weak uniform countable additivity condition is satised, we show that there are a nite number of orthogonal invariant measures under the usual drift criterion, and
These tasks are: (1) determine the isochrones (contour lines of equal time of ¯ow) to the watershed outlet and the drainage areas that contribute to the isochrones; (2) assess
In order to address this problem in the use of 30- arc-second DEM, we adopt the following procedure: (i) estimate topographic index using the single ¯ow algorithm from the
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
For fBm media, this size dependence can be explained using an eective variance that increases with increasing size of the ¯ow system.. However, the magnitudes of the
The constant ¯ow rate experiments show a signi®- cant reduction of the dispersion coecient in case of an increasing density dierence between the resident and displacing ¯uids..
In order to illustrate that completely different results are possible for the same problem using Standard Galerkin, Petrov-Galerkin and Fully-Upwind Galerkin finite element
