STRIMA II

Saxon-Czech Flood Risk Management II

Objectives

The STRIMA II project supports the cross-border cooperation in flood risk management between Saxony and the Czech Republic. The focus here is on precautionary measures and risk prevention toreduce the consequences of river floods and heavy rainfall induced floods. This also considers an increase in intensity and frequency of such events due to climate change. A major concern of the project is the creation of cross-border data exchange and risk analysis methods to support the comparability as well as to strengthen information and actor networks.

Approach

In this project, the IOER was responsible for developing and refining of methods to assess the potential flood impacts on buildings, land usage as well as transport and waterway infrastructures. It includes the identification and analysis of effects due to appropriate flood precaution measures. Options for flood prevention are systematized and classified before being transferred into a catalogue of measures and a web-based information system. This allows an assessment of flood measure effects and the drawing up of recommendations for their implementation. The developed methods are being tested in case studie areas of Saxony and the Czech Republic.

Main results

Buildings

Functional enhancement of the synthetic model approach to consider the effects of flood mitigation measures on buildings
Development of an overall concept, elaboration of the detailed calculation guideline and designing of mock-ups for the interactive WebGIS application FLOOD.Bi. The new information tool illustrates the effects of flood mitigation measures on residential buildings.
Development of the data model and analysis of research data as a basis for the R2-module. The R2-module is key part of FLOOD.Bi.

Environmental goods and Land use

Development of a method for assessing potential flood damage to agricultural crops

Watercourses and traffic infrastructure

Development of a method to characterize the vulnerability of watercourses and traffic infrastructures
Guidelines and fact sheets to systematise adaptation measures for the reduction of flood damage to watercourses
Case studies to operationalize method development and adaptation measures on Saxon and Czech rivers
