Systematic rehabilitation planning: a new decision support system for targeted morphological river restoration

Abstract

Working with decision support systems (DSS) in the water management sector often requires well-grounded knowledge and an expensive data collection. This paper presents a new approach with regard to the identification of adequate hydromorphological measures taking especially the land availability and the local restrictions of the planned stream sections into consideration. It is intended for people with no broad water management background dealing with the planning, realization or permission of measures for water bodies. The essential module is an easy kept questionnaire for the derivation of measures. It leads the user through a logical sequence of questions resulting in target-aimed measures, visualized by pictograms. This tool is also suitable for documentation purposes.
