Dynamic modelling of soil water acidification: display and presentation of results for policy purposes

Abstract

Dynamic models for soil and water acidification and recovery are becoming increasingly important tools in determining policy for future emissions of air pollutants in Europe. Dynamic models represent the next step in complexity from the steady-state models used heretofore in conjunction with estimating critical loads. This report gives an explanation of dynamic models, their evaluation, uses and uncertainties and the various alternative ways to present results. The report is intended for use by the non-specialist, and in particular for policy-makers.
