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 137Cs and 210Pbex measurements, bulk soil samples were collected in cultivated site from Karkın Village in Middle Gediz Basin. Soil loss rates were calculated from 137Cs and 210Pb inventories of the samples using the proportional and the mass balance conversion models. The activity concentrations of 137Cs and 210Pb 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 137Cs and 210Pb 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 137Cs and 210Pb 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.
