摘要

Accurate assessment of the fate of salts, nutrients, and pollutants in natural, heterogeneous soils requires a proper quantification of both spatial and temporal solute spreading during solute movement. The number of experiments with multisampler devices that measure solute leaching as a function of space and time is increasing. The breakthrough curve(BTC)can characterize the temporal aspect of solute leaching, and recently the spatial solute distribution curve(SSDC)was introduced to describe the spatial solute distribution.
