Use of aerial photographs for soil erosion studies

Using air photos soil loss from agricultural fields has been estimated in respect of the Rana and granitic areas of south-west of Merida, Spain, applying the universal soil-loss equation. The results of soil-loss have been shown as soil erosion susceptibility and soil erosion hazard classes. This study has shown that large scale aerial photographs (1:12500) are quite useful in evaluating many of the parameters of the universal soil loss equation with limited field checks.
