The ability of dams to affect the ecology of a river and to prevent the movement of migrating fish is a concern around the world. FLOW-3D is frequently used to improve existing fish passage designs and to develop novel approaches based on the physiological characteristics of different fish species.

FLOW-3D is also used to design aeration systems to increase concentrations of dissolved oxygen in impounded waters and to provide the basis for the development of a new generation of geographical information systems to assess environmental impacts.
