Coastal Engineering

Course Description:

This course aims to provide students with specialized knowledge on mechanisms of coastal sediment transport, morphological feedbacks to the structures and coastal erosion. It also aims at learning the design and spatialisation of coastal protection projects using relatively simple mathematical expressions and advanced mathematical models

Prerequisite Knowledge

It is recommended that students have the basic knowledge of Maritime Hydraulics.

Learning Objectives

Upon successful completion of the course, students will be able to:

  1. Understand the basic principles of coastal sediment transport and morphological feedbacks from technical works through equations and simple numerical models

  2. Understand the mechanisms of erosion and sedimentation in the coastal zone

  3. Solve basic components of coastal engineering problems by understanding the processes of wave propagation in coastal areas and the interaction of waves with coastal structures

  4. Design of coastal protection structures using empirical relationships and mathematical models

Teaching Methods

Teaching methods Lectures in class. Solving of simple examples and problems in the class. Discussion of case studies.
Teaching media Presentations in the Table. PowerPoint Slides. Calculations on PC via Excel and computational codes.
Computer and software use Students solve complex simulations of coastal processes using PC at home and at the Laboratory of Harbour Works.
Problems - Applications YES
Assignments (projects, reports) Students complete projects during the semester with the continuous supervision of the teachers six-month work in groups of 3-4 people. For each topic they write a Technical Report, which is corrected by the teachers and returned.
Other Educational Excursion. There is an option of developing individual voluntary bibliographic work.

Student Assessment

  • Final written exam: 65%
  • Assignments (projects, reports): 25%
  • Oral exam: 10%
