Hydraulic structures generate economic and social benefits. They make it possible to control the changes in the riverbed and valleys which favors water management through the development of water resources and water use.
Scope of activities of waterway engineering takes into account:
- technical and natural river/stream training
- development of lowland rivers with barrages forming water reservoirs with constant water levels (weir) allowing for inland waterway shipping, operation of hydroelectricity and water intakes
- development of mountain rivers by dams forming water retention reservoirs (used in active flood protection and water storage as well as operation of pumped-storage hydroelectricity)
- construction and operation of water intakes, mittelland canals, hydro engineering adits and pipelines
- dredging
- underwater works
Activities related to the maritime engineering include:
- structures located in the area of maritime ports, as: breakwaters, wave breakers, transhipment and parking wharves, islands, wave absorbers, boulevards
- structures located in the area of marinas, especially mooring-reloading islands, reloading piers
- coastal protection structures, such as seawalls and groynes, shore breakwaters, rapids, linings, embankments against storm, descents to the beach
- structures of stationary marine navigational signs, in particular marine lanterns and electric beacons placed onshore and inside sea basins, onshore and offshore beacons, leading lights and light navigation signs, navigational dolphins
- marine canals and locks
- structures associated with sea surface water abstraction, particularly water intakes, pipelines or underwater tunnels, water storage tanks
- structures associated with the discharge of water into the sea, especially underwater sewage pipelines, cooling water discharge constructions
- structures for beach recreation, especially walking piers and waterslides
