Euroharp - Review and Literature Evaluation of Quantification Tools of Nutrient Losses

This preliminary scientific review has been undertaken before model results are available, and is intended to provide information concerning the strengths, weaknesses, capabilities and potential limitations of different models predicting nitrogen and phosphorus loss from agricultural land to surface waters. This assessment included consideration of the boundary conditions, process description, and the pathways that are taken into account by each model. In this report the outcome of the intercomparison is described as a result of the work of Work Package 3 (WP3) focusing on phosphorus and Work Package 4 (WP4) focusing on nitrogen.
