Model EH-REK v 1.0

EH-REK v 1.0 Model decision support system to assess risk and prevent cyanobacterial blooms in small urban reservoirs

General information

GENERAL INFORMATION

EH-REK model is an element of the system which supports decisions in terms of activities focused on rehabilitation of small urban reservoirs to improve water quality and reduce the risk of cyanobacterial bloom formation.

The model is dedicated to the reservoirs with the surface of over 10 ha with the average depth of up to 2 m.

The aim of the model is not to automate decisions but to support the decision making process based on data as well as improve management efficiency.

EH-REK model has been developed based on the ecohydrology concept, and implemented and tested under a UE project: LIFE+ ‘Ecohydrologic rehabilitation of recreational reservoirs Arturówek (Łódź) as a model approach to rehabilitation of urban reservoirs (EH-REK)’ (LIFE08 ENV/PL/000517).
