Input to engineering III & management I: Waves shaping the coast

  • The Questions: Where to build? Where NOT to build:

Akmeņrags cape, Latvia, 2005

Answers: Wave- driven sediment transport: convergence – divergence – changes in time

The question:

Can we do something to “handle” oil pollution?

The goal: Reducing the consequences of disasters

  • by smart adjusting the location of human activities
  • so that the pollution will not hit the coasts

Risk=probability  cost

The method: solving the inverse problem:

  • quantification of offshore areas
  • in terms of their ‘ability’ to supply coastal pollution
  • through current-driven transport

Reducing the consequences

  • f offshore disasters by

smart adjusting the location

  • f human activities so that

the pollution will not hit the vulnerable regions Examples of environmentally

  • ptimised fairway designs for

the Gulf of Finland (Andrejev,
