Using these discharges at the places where the rivers enter the country (for the Rhine is that near the village of Lobith, for the Meuse is that near the village of Borgharen), one may calculate the waterlevel along the river. One should of course take into account the effects of bifurcations, barrages, weirs, etc. In the Netherlands the general waterlevel and discharge pattern is calculated using a one-dimensional computer model with many branches, the detailed waterlevel is calculated with the use of a two-dimensional computer model. The accuracy of these models is in the order of a few decimeters for design circumstances (for those situations the models cannot be calibrated).

Gutmann et al. [3] propose a very generic method, called Vector Field SLAM (VF-SLAM), for modeling continuous vector fields in the SLAM context. The method utilizes bilinear interpolation with an automatically updating coarse (1–2 m) regular grid. As an example, they use infrared-based vector field in a small 2D planar environment (). Approximately decimeter accuracy is achieved. The method is later evaluated in home-sized environments with area of [18].
