We have to realize a isoconcentration map of percloroethilene plume in the groundwater. The concetrantions are high scattered, in fact they passe to 2600 µg/L to 0 µg/L in a small geografic context (1500x500 circa linear meters). Using kriging algorithm and/or linear triangulation the obtained results are not correct caused by asimmetric shape of the site, so they cause an incorrect contaminant isocontour passed trhough the uncontaminated control point. Definitely, there's a method or an option to appling in the previous used method with the aim to obtained or simulate the distribution?
We have applied yet this methods. Then the results are too wide. Maybe we have to insert some control points manually to define new perimetral constrains?
I would suggest to add manual points with defined concentration to ensure the correct general shape.
Yes. We have selected the linear triangulation method and the results are quite reasonable, even if I think adding points manually is a forced procedure. So thank to you two for your answers
IDW will work if the sampling points are taken closely or in a GRID pattern.
