yes you are correct. The blue data presents boundary with zero velocity value. The reason I've chosen Kriging is that I think there is a spatial relation between blue and red data points but as I had written I want to ignore only the spatial relations between blue points.

Hi, I would like to model the velocity of water flow in an open channel by Kriging method(I asked the possibility of using Kriging for this aim before and it seems that this method can be used for every condition). I collected my data on the cross section of the channel and depicted as a point data. The scattered data picture is attached and as you see two red and blue sorts of data(blue data have zero value while red data have nonzero value) and the coordinate of each point data is shown in x,y plane. I try to run Kriging method in ARC GIS10 with one condition which is: the blue points must have no spatial relation with the other blue points. How can I apply the mentioned condition in ARC GIS10?(I think this condition influences on empirical semivariogram and the weights related to the blue point data)

I try to model the velocity of water flow in an open channel.I collected My data on the cross section of the channel and depicted as a point data (x,y are the coordinates of each point in the plane and z value is the respective velocity of water flow at that location). When I visualized my data in arcgis, apparently I can see 4 clusters of points in my data. one of them is horizontal, two of them are vertical and there is one cluster of points in the center of my data cloud. (please find the configuration of my data here: http://i64.tinypic.com/2vt41dv.jpg). So, I would like to know, if I can use Kriging Interpolation method for this configuration of data in order to estimate the unknown velocity values between the known points?? Thanks in advance.
