The construction of big works

The building of dikes, piers, roads, energy plants, etc. modifies the landscapes and interferes with natural processes. These changes have to be kept in mind during the first planning stages. Let us image to stop a river flow by building a dike. We will have to take the following aspects into consideration:

  • the stability of the building;
  • the quantity of river sediments that will not reach the sea but that will deposit on the dike lake;
  • the danger of erosion for the beaches that are located close to the river mouth.

The accurate study about the environmental compatibility of a building during its design is called assessment of environmental impact.
