[R-sig-Geo] Spatial interpolation of river network observations

[Ulrich Leopold]

Dear all,

I would like to interpolate 17 pollution observations in a storage lake
in 3 dimensions (x,y,z).

As I understand variogram analysis and kriging are not straightforward
as we are dealing with non-euclidean (hydrologic) distances and
down-stream direction.

Could someone point me to some algorithms which can roughly estimate the
3d pollution body accounting for hydrologic distances?

Attached is a file which shows the sampling locations and the storage lake.

Thanks very much.

Best regards,
Ulrich
