Screens and Curtains

The application of geosystems in hydraulic and coastal engineering is in full development. However, in many situations no reliable and proven calculation methods are available for the dimensioning of geosystems. In this chapter, literature related to a selected number of screens and curtains is reviewed with respect to the dimensioning and application of these systems. Many different geosystems applying screens have been constructed and typical applications are listed below. Floating screens ( Section 8.2 ) and bottom screens ( Section 8.3 ) are described in more detail. Floating and bottom screens are made of a synthetic fabric and they are kept in position by anchor cables. Simple calculation methods for the forces and deformations in screens and membranes are presented. Some field experience with geosystems are evaluated briefly in Section 8.4 .
