Spatio-temporal modeling of 210Pb transportation in lake environments

---

Abstract.
Radioactive particlemovement analysis in any environment gives valuable information about the effects of
the concerned environment on the particle and the transportation phenomenon. In this study, the spatiotemporal point cumulative semivariogram (STPCSV) approach is proposed for the analysis of the spatiotemporal changes in the radioactive particle movement within a surface water body. This methodology is
applied to the 210Pb radioactive isotope measurements at 44 stations, which are determined beforehand in
order to characterize the Keban Dam water environment on the Euphrates River in the southeastern part
of Turkey. It considers the contributions coming from all the stations and provides information about the
spatio-temporal behavior of 210Pb in thewater environment. After having identified the radii of influences
at each station it is possible to drawmaps for further interpretations. In order to see holistically the spatial changes of the radioisotope after 1st, 3rd and 5th hours, the radius of influence maps are prepared and interpreted accordingly.
