Brief description:
Mud often occurs in large quantities in estuaries and along coasts in the neighbourhood of river mouths. It contributes to the shaping of our coastline. Mud is of great importance from an environmental point of view (e.g., as a nutrient source for many living organisms, as a natural protection of the coast against waves). But it also causes siltation of navigation ways and harbours and is prone to heavy pollution.
This course will examine the various processes of cohesive sediment transport, how they help to understand mud behaviour and its important environmental role, and how science and engineering contribute to the study and mitigation of the related problems it can cause. Attention is given to the physics, some chemistry and biology of the processes, and to experimental and mathematical research tools. Some simple experiments will be carried out and a field trip organised.
Objectives:
Providing insight into the mechanics of cohesive sediment transport processes and how they help to understand the environmental and socio-economic importance of coastal and estuarine mud research.
Technical programme to be followed: details attached
Prerequisite of the course: Basic knowledge on fluid mechanics
Course exam: Presentation of project work on a case study

Coastal and estuarine mud:
why we like and dislike it.
Theory 1&2 (2x "1.5 hr seminar)
·What is mud? (Erik Toorman)
-Characterizing mud
·Moving & shaping mud (morphodynamics) (Erik Toorman)
-Mud transport processes
-Engineering problems (design of structures, prediction of morphology and siltation, restoration …)
Theory 3 ("1.5 hr seminar)
·Mud as ecosystem (Dr. Steven Degraer, Marine Biology, UGent)
-Tidal and intertidal flats
Theory 4 ("1.5 hr seminar)
-Mud as nuisance (siltation, dredging, pollution) (Dr. Dries Vanden Eynde, MUMM)
-Dredging strategy: weighting the options
-Dredged material dumping at sea
Theory 5&6 (2x "1.5hr seminar)
-Studying & forecasting mud (measuring and modelling mud) (Erik Toorman)
-Why ?
-Short-term
-Long-term
-Measuring what ?
-Mud transport modelling: possibilities and limitations, calibration, validation, interpretation
-Examples:
(For example:
-Mont St. Michel (France)
-Building on mud: Airports at sea (Kyoto, Inchon, Rotterdam, …)
-Avoiding mud in harbour basins (sediment traps, current deflection wall, permanent mud pumping station, …)
-Mud from space: using remote sensing (Jaak Monbaliu & Stefanie Adam, KUL)
Theory 6 ("1.5 hr seminar)
-Tropical mud (Prof. P. Augustinus, U. Utrecht & Erik Toorman)
-Mud as wave absorbing protector (natural: India, Suriname, … - artificial: Mexican Gulf (Louisiana), …)
-Interaction with mangroves (mangrove ecosystem / Suriname …)
-Restoration of mangrove coasts (Vietnam, …)
-Mud slidings in mountainous areas (debris flow)
Theory 7 ("1.5 hr seminar)
-Mud and integral water management: case studies
-Scheldt river (lecturer to be confirmed):
-Controlled floodplains
-Long-term vision (cf. ProSes)
-Mud flats: Yzermouth nature reserve
Lab. Experiments:
-Settling, flocculation, deposition & consolidation
