The barrier theme argument is used to specify the location of linear features known to interrupt the surface continuity These features do not have z values Cliffs faults or embankments are typical examples of barriers Barriers limit the set of the input sample points used to interpolate output z values to only those samples on the same side of the barrier as the current processing cell Input sample points that lie exactly on the barrier line are included in the sample set for both sides DHI Software 2000 MIKE SHE Converter 1999B 12 DHI Water amp Environment DHI Institut for Vand amp Milj of the barrier When barriers are specified the processing time is significantly extended Spline The basic form of the minimum curvature Spline interpolation imposes the following two conditions on the interpolant The surface must pass exactly through the data points The surface must have minimum curvature the cumulative sum of the squares of the second derivative terms of the surface taken over each point on the surface must be a minimum The Regularized option modifies the minimization criterion so that the third derivative terms are incorporated into the minimization criteria The Weight argument specifies the weight attached to the third derivative terms during minimization referred to as tau in the literature Higher values of this term lead to smoother surfaces Values between 0 and 0 5 are suitabl
