TEFER Project (TURKSAT)

Slide14: 

TEFER project will support the installation of 129 automatic real-time hydrometric, 206 automatic real-time meteorological and 3 radar stations (Doppler) in the first phase, so that real-time data will be available in order to run the operational flood forecasting models.
