So im one of those guys that can best learn with pictures so ive added
tons of them, that’s the way I learn fastest.

Part 1 - Introduction to hydraulic structures
The functions of the hydraulic structures should be known, as well as the relation
between the function(s) and the structure. Be able to ‘visualize’, to make a rough sketch
of these structures.

The sketches/photos are added in Appendix A.

Shipping
1. Navigation locks, ship-lifts and inclined planes (Schutssluizen)
 Vertical and horizontal transport of ships (cross a water-level difference)
- whilst maintaining the water-level difference
- whilst water flows form high to low level side (high quantities/uncontrolled)
 Ships passing weir or water retaining structure

2. Weirs (fixed or with moveable gates) (Stuwen)
 Ensure water depth upstream

3. Quay walls (Kademuren)
Primary
 Enable berthing and mooring ships
 Support cranes and vehicles
 Support (temporary)
storage of cargo Structural
 Retaining of soil and preventing underground flow
 Retaining of (ground)water
 Bank/erosion protection

4. Jetties (Stijgers)
 Berthing + mooring ships
 Support loading/unloading cargo/crew
L-shape: lower part of the ‘L’ parallel to the coast, outside of the surf zone.
T-shape: for larger vessels, as tankers and bulk carriers.

5. Dolphins (Meer-/Bolderstoelen)
Breasting dolphins:
 resist the horizontal
load caused by
berthing ships

Mooring dolphins:
 resist horizontal loads and
provide bollards for holding
the ships mooring lines

6. Approach walls and fenders (geleidewerken en stootkussens)
 Guidance ships to/in desired direction to prevent collision with hydraulic structure
 Slowing down/mooring of ships
 Fenders absorb energy

7.1 Breakwaters (golfbrekers)
Used for the benefit of shipping
 Shelter for wave action
 Shelter for currents
 Reduction of sedimentation
 Visual guidance

7.2 a Groynes (strekdammen)
 Foremost used for the reduction of sedimentation
 Divert currents
7.2b River groynes (kribben)
 Cause higher flow velocities in the narrowed summer bed
 Reduce meandering of the river
 Increase the navigational depth

Flood protection
8. Dikes
Main function(s)
 Manmade structure to prevent flooding, soil structure (embankment)
Functional requirements
 Sufficient retaining height (to withstand design water levels and wave heights, to prevent
overtopping)
 Revetment on the outer slope (withstand wave impact and currents, to prevent erosion)
 Outer berm (to break the waves, to reduce overtopping)
 Inner berm/gentle inner slope (for extra slope stability, to prevent failure from the driving
moment of a circular slip body/macro-instability)
 Piping berm (kwelsloot) (provide a longer seepage path, reducing probability of piping)
 Slope angle (influence wave run-up and dike stability)
 Soil composition (combine soil properties; sand/gravel  stable; clay  impermeable)

9. Closure dams
Mainly used for the closure of tidal inlets and estuaries
 Reclamation of land
 Shortening of the length of sea defences
 Creation of fresh water reservoirs
 Creation of tidal energy basins
 Creation of fixed-level harbour approaches

10. Storm surge barriers
 Retain water, allow passage of ships and water (tidal flow, river discharge), generally not at
the same time
 Manmade (hydraulic) structure

11. Discharge regulating structures
 Control the discharge in rivers when a flood is imminent. Divert the water to another branch
where the flood thread is less severe.
