In order to reach that goal several modifications are made to both methods, those modifications are detailed in the paper. The result is a very accurate tool, specially suited to deal with non linear problems. To show the above an example of coastal sea bed erosion and sedimentation has been implemented and its results and advantages shown in the paper. Natural Neighbor Interpolant Natural neighbors may be defined as follows: For every set V = {^1,^2, • • • ,Pm} of ra different points on E. And for each i on Im is defined the set of Voronoi poly topes related to V. Every pair of points whose Voronoi poly topes have common frontiers, are called Natural Neighbors; for each point there always exists a set of Natural Neighbors Let now V be a set of m different points on E, with ra > n, not contained on a subspace of E of dimmension less than n. An open sphere £ on E is called Covering Sphere related to V, if and only if : i) 8 contains no point of V.

This paper shows modeling of such phenomena that gives some light to the understanding of it and also provides the opportunity to improve the effectiveness of the current procedures.

This version is based in the use of Teodorescu transform and we show the use of its numerical version.

However consequences of such channels are still being studied. Our model intends to be a practical contribution to this subject and is devoted specifically to the channel itself and its surroundings.
