> Introduction
Estuaries and Coastal Zones Division
The Estuaries and Coastal Zones Division (NEC) of LNEC’s Hydraulics
and Environment Department was created in 1961 and pursues its activity
in the following domains:
|
|
Estuarine and coastal hydraulics
- Flows driven by tides, wind and river flows;
- Coastal currents;
- Stratified flows;
- Salinity intrusion in estuaries;
- Wind-wave propagation.
|
|
|
Sediment dynamics in estuaries and coastal
zones
- Coastal dynamics and protection;
- Morphodynamics and stability of tidal inlets;
- Processes and evolution of estuarine margins;
- Dynamics and behaviour of cohesive sediments;
- Dredging and disposal of dredging spoils;
- Laboratory characterization of cohesive and non-cohesive
sediments.
|
|
|
Environmental quality in coastal zones
- Water quality in coastal systems;
- Effluent disposal and submarine outfalls;
- Systems of environmental indicators;
- Integrated coastal zone management.
|
Various types of tools are used:
|
|
Numerical models
- Shallow water flows;
- Short wave propagation;
- Nearshore currents;
- Estuarine and coastal morphodynamics;
- Advection-diffusion;
- Cohesive sediment transport;
- Water quality.
|
|
|
Laboratory equipment (Experimental
facility for Cohesive Sediments)
- Annular flume, sedimentation column and consolidation columns for
the study of cohesive sediment behaviour;
- Sedimentology laboratory for the physical characterization of
cohesive and non-cohesive sediments.
|
|
|
Scale models
- Two-dimensional channels to study the stability of beach
profiles;
- Tri-dimensional tanks to study the longitudinal stability of
beaches.
|
|
|
Field data acquisition
- Topo-hydrographic surveys
- Measurement of physical and chemical water parameters
- Sediment collection
