Recent achievements in expertise and experience
Some of the most valuable achievements are compiled in comprehensive
manuals and guidelines. They refer to earth and rubble stone dams and dikes
constructed on soft ground.
Soft ground engineering
CUR report 162 - Building on Soft Soils (1996). The Dutch knowledge and
experience is gathered on design and construction of earth structures on and into
highly compressible soils of low bearing capacity. The design process, including
soil investigation, probabilistic methods and mechanical behaviour, is extensively
discussed, and the construction, including fill materials, building methods and
maintenance and management, are outlined. Special information is given on
parameter correlations, software codes and validation methods of calculations, and
practical cases are worked out. A special chapter deals with behaviour of peat and
organic clays.
Rubble mounds and stone revetments
CUR/CIRIA Report 154 - Manual on the Use of Rock in Coastal and ShoreLine
Engineering (1991). Knowledge and experience obtained from several large
projects, like the Delta Works, has been gathered by British and Dutch engineers.
The manual includes data collection, design, construction and maintenance aspects.
Chapter 4 describes the dynamic hydro-geotechnical stability of rubble mound
structures and stone covers, in particular when exposed to wave attack and
earthquakes. The manual contains various practical design concepts and formulae,
and elaborated examples on the probabilistic approach. It also describes
instruments and numerical tools, and the corresponding legislation.
Dike technology
A long list of guidelines and manuals, technical reports and fundamental studies
is available, mostly published under the auspices of the ENW (Expertise Network
Water Defences, formerly TAW, founded in 1965), a committee that advises the
ministry in charge of water management. Amongst its members are representatives
of the ministry, governmental departments, the water boards, the provinces, the
universities, and knowledge institutes.
Technical guidelines, manuals and regulations are coherently organised and
regularly updated for the use by the water boards for the six-annual evaluation. The
actual list of main guidelines and regulations includes
- Fundamentals for Water Defence (1998);
- Regulation Hydraulic Boundary Conditions (2007);
- Regulation Safety Evaluation Primary Water Defence Systems (2007);
- Guide line Environmental Effect Report;
- Guide line River Dike Design, part I, lower river regime (1985);
- Guide line River Dike Design, part II, upper river regime (1989);
- Guide line Rivers (2007);
- Guide line Sandy Coasts (2002);
- Guide line Sea and Estuary Dikes (1999);
- Guide line Water Defence Special Structures (2003);
- Manual Actual Strength of Dikes (2009);
