Özet
Gediz Basin supports the considerable amount of Turkey's agricultural need and erosion have long been causing a serious problem in the basin. To evaluate the erosion rate by using Cs-137 and Pb-210(ex) measurements, bulk soil samples were collected in cultivated site from Karkin Village in Middle Gediz Basin. Soil loss rates were calculated from Cs-137 and Pb-210 inventories of the samples using the proportional and the mass balance conversion models. The activity concentrations of Cs-137 and Pb-210 were measured and their values are obtained in the ranges of 0,4 - 24 Bq kg(-1) and 17-58 Bq kg(-1) respectively. The Cs-137 and Pb-210 inventories of reference, erosion and deposition are obtained as follow in sequence; 3162 Bq m(-2), 2285 Bq m(-2), 6272 Bq m(-2) and 3723 Bq m(-2), 2544 Bq m(-2) and 4138 Bq m(-2). Soil redistribution rates, within the field, determined for Cs-137 and Pb-210 10,8 t ha(-1) y(-1) and 13,07 t ha(-1) y(-1) and the mean erosion rates for the eroding area was obtained as 25,8 t ha(-1) y(-1) and 54,05 t ha(-1) y(-1) respectively.
