Erosionsskydd i strandzoner
Erosion in coastal areas is a common problem all around the world. The range of the problem depends on several factors, i.e. type of bed-rock and soil, wind and wave climate. Another factor is whether the area is of high interest, i.e. if the area is important for tourism and recreation, if there are houses and other buildings close to the shoreline or if it is a site of special scientific interest. The higher the value, the more money is spent to keep the problem in check. There are several ways to solve the problem, in this thesis, I have studied the most common solutions. Even though coastal protection is effective for a specific site, it may cause erosion further down stream. There are lots of things you have to take in consideration before you start to build. The economy plays a big part.
The reason I chose this subject, is because I'm very interested in the forces of nature and the fact that the climate seams to be changing, with more extreme weather as a result. As more and more coastal areas get exploited the importance of coastal protection gets bigger.
The first part of this thesis is a literature study about erosion and different types of coastal protection. In the second part I've taken a look at already built constructions and tried to compare how they were built and how they work, with the general guidelines of the manuals I've studied. There are no perfect solutions, you have to adopt the design from one place to another, because of the different conditions.
