- Abstract
- Land applied chemicals from different origin may have a negative impact on the quality of surface and groundwater. Migration of dangerous chemicals through the vadose zone is therefore a possible pollution pathway for vulnerable drinking water resources. Effective approaches for protecting groundwater resources builds on a thorough understanding of the flow and transport of chemicals in the vadose zone. Unsaturated flow and transport models may therefore be used as tools to predict flow and transport supporting risk management and operational decision making. In this paper, we show how models for pollutant dispersion modelling in soils have been developed. The developments are based on the use of flow and transport models for assessing risks in the agricultural sector, in particular to evaluate risks associated with the use of agro-chemicals. We believe, however, that the concepts and approaches presented in these models are sufficiently generic for modelling chemical load of vulnerable groundwater bodies also from non-agricultural diffuse source. Particular emphasis in this report is put on the limitations of the current modelling approaches for management applications, the problems associated with the estimation of the required modelling data and parameters, and (iii) the transfer of scientific know-how into operational decision-making tools.
