A Tisza River Basin Analysis Report was developed by the Tisza Expert Group of the International Commission for the Protection of the Danube. The Report is an important step for the preparation of a river basin management plan under the EU Water Framework Directive. Ecologic was commissioned to assist the Tisza Expert Group with the development of three chapters on the identification of artificial and heavily modified water bodies, on the assessment of risk of failure to reach the WFD environmental objectives for surface water bodies and on the characterisation of groundwater bodies.
