287 Spatial and Temporal Variability In Contaminant Transport

Oral Session

Information regarding the impact of soil properties, topography, and climatic conditions on water and contaminant transport is required to improve and validate predictive models. In this topical session, we will review recent developments to assess the spatial and temporal variation in contaminant transport. For example, this session will include discussion of changes in water and contaminant transport in cropped soils, hilly landscapes, disturbed soils, environments subject to wide variation in climatic conditions, etc. This information will be useful to those interested in contaminant mobility and persistence and crop productivity under inherent or imposed variable conditions.
