In this case study you will identify changes that occurred at the Sf. Gheorghe mouth, the southern branch of the Danube delta, using Landsat images.

You will then track the evolution of the Sacalin barrier island and understand the implications of this for the entire coastal area.


This case study includes:

  • a background section
  • exercises
