The EUROHARP Toolbox is a database and web site providing information and test results about a large number of tools/models aimed at quantification of nutrient losses from diffuse sources. The first version of the Toolbox was developed during the EU-funded EUROHARP-project, but has later been further extended to cover other similar tools. The Toolbox provides comprehensive search functions and user-friendly ways to present and compare the capabilities and performance of the tools.

Modellers working within this field of science are strongly encouraged to submit information about their own tool.
