About Project Flowtech

Estimation of Environmental Flows using Unmanned Aerial Vehicles and Acoustic Equipment based on fish habitat requirements.

Human interventions to the natural streamflow regime are rising, without most of the time taking into account the environmental water needs.

Environmental water is the amount of water required to sustain freshwater and estuarine ecosystems and the human livelihood that depends on these ecosystems. Ηydromorphological pressures alter the natural flow regime of rivers and can be directly linked to impacts on their physical and chemical attributes and processes.

The environmental flow regime is a key element in determining river processes, affecting ecosystem health.

There is an urgent need to develop sustainable environmental flow management guidelines to mitigate the risk associated with alterations to the flow regime.


Flowtech will harvest and upgrade the existing knowledge and experience focusing on the estimation of environmental water needs in a more integrated way, regardless of policy restrictions.

More specifically a Physical Habitat Simulation Approach for fish species will be applied in Greek rivers by developing fish Habitat Suitability Curves and hydrodynamic models,incorporating state of the art technology with the main objective to achieve fast, repeatable and highly accurate results for the data collection regarding the fish habitat measurements.


The FlowTech project is funded under the 2st Call for Research Projects ELIDEK (HFRI, Hellenic Foundation for Research and Innovation) for the support of Post-doctoral Researchers by the General Secretariat of Research and Technology (GSRT) within the scientific research area for the Environment and Energy (Project ID: 454).
