Meet Andra-Rada Iurian (OSP Award 2013)


Andra-Rada Iurian has received the EGU Outstanding Student Poster (OSP) Award for her presentation “The uncertainty given by the input parameters in the radiometric modelling of soil redistribution rates“.

Who is Andra?

AndraAndra-Rada Iurian is currently finishing the PhD studies at the Faculty of Environmental Science and Engineering, Babes-Bolyai University, Romania. Her research interests includes: (i) the application of fallout radionuclides (137Cs, 210Pb and 7Be) to assess the rates and characteristics of soil redistribution, (ii) environmental radioactivity measurements through gamma and alpha-ray spectrometry, and (iii) radioecology. Her PhD project is focused on the application of fallout radionuclides in soil erosion and sedimentation studies and it is conducted under the guidance of Prof. Constantin Cosma. The poster at the EGU General Assembly 2013 presented an alternative method to statistically derive the effective diffusion coefficient and the convective velocity of 137Cs in undisturbed soils. It was also highlighted the impact of the different input parameters of the Diffusion and Migration Model on the calculated soil erosion magnitude. In a subsequent study, the undersigned also tested for the first time in her country the combined use of 137Cs and 210Pb to quantify soil erosion changes in cultivated fields at different temporal scales.
