The Modular Stepwise Procedure for the analysis and assessment of watercourses includes survey methods in the areas of hydrodynamics and morphology, biology, and chemical or toxic effects.

The present report describes how to assess watercourses using chemical and physical parameters. The water quality requirements are either those specified directly in numerical terms in Annex 2 of the Water Protection Ordinance or are obtained by converting the qualitative requirements specified in this Annex into quantitative terms (“target values”). Indicator values are obtained by aggregation of the chemical parameters measured for the water samples. They can the be compared with the requirements and target values in an assessment based on a 5-point scale.
