TC217 Land Reclamation

Land Reclamation

Objective 1: Dissemination

Land reclamation is one of major geotechnical activities in many countries. Many challenging land reclamation projects have been carried out in recent years. These include the Kasai International Airport in Japan, the Changi International Airport in Singapore, the Hong Kong Chek Lap Kok International Airport, the Seoul Incheon International Airport, the Palm Deria in Dubai, The Port 2000 of Le Havre in France, The Hamburg Airbus A380 Industrial Platform Site in Germany, and the Port of Brisbane in Australia. The importance of land reclamation has been recognized by ISSMGE. There is an ISSMGE-TC201 on Geotechnical Aspects of Dykes and Levees, Shore Protection and Land Reclamation. However, during the TC201 committee meeting in Paris in Sept 2013, members of the TC201 felt that as both dikes, levees and land reclamation are two major geotechnical activities, there should be a separate TC on land reclamation. This will also allow TC201 to concentrate on the issues related to dyke, levees and shore protection. This is the background for the proposal of this new TC. Land reclamation activities include mainly coastal and river delta developments to expand land for ports, airports, business centers, shopping centers, logistic terminals, factories, residences, amusement parks, etc. There are also activities for land reclamation of old mining sites, quarries and ponds. Most of the countries along the coast have activities related to land reclamation. Various innovative geotechnologies have been developed and used for various land reclamation projects. Land reclamation in coastal development has to meet two different social and environmental demands: on the one hand, a growing need to develop and increase land space and facilities, on the other hand, a corresponding need to respond to geoenvironmental issues in preserving or restoring rich biodiversity in coastal regions such as intertidal flats and shallow seas, which have been lost as a result of reclamation. Therefore, the geoenvironmental aspect is also an issue related to land reclamation activities.

Objective 2: Guidelines & Recommendations

The proposed new ISSMGE-TC on Land Reclamation will focus on the following two broad issues:

a. Geotechnical issues

- To develop and update geotechnologies to overcome geotechnical challenges related to coastal development, including site investigation methods, laboratory and in-situ testing and interpretation methods corresponding to various stages from sedimentation to consolidation, evaluation of stability of geotechnical structures, prediction of long-term consolidation for large scale manmade island, large-scale dredging and its impact, development of environment-friendly recycled/reused material, land reclamation methods, ground improvement methods, field monitoring and applications of the observational method in construction and maintenance.

b. Geoenvironmental issues

- To minimize environmental impacts due to coastal development through development of construction methods for environment-friendly seawalls, design and monitoring of artificial coastal structures including intertidal flats, reliability and durability of development of new environment-friendly material. The main aim of the TC is to promote a greater interaction among engineers engaged in geotechnical and geoenvironmental engineering related to land reclamation so as to achieve greater cooperation and facilitate the exchange of information, experience, knowledge, and new ideas in these two areas. In the next four years, the committee would endeavor to organize at least two small to medium size workshops, with at least one of them to coincide with a regional conference under the auspices of ISSMGE (e.g. the 15th Asian Regional Conference in Fukuoka, 2015 or the 19th ICSMGE in Seoul, 2017). In each workshop, the two themes listed above will be discussed. One principal aim of these workshops is to ensure publication of excellent case histories and associate construction experience, as well as technical proposals for future projects.

Objective 3: Conference Assistance

TC217 session during the 15th Asian Regional Conference on Soil Mechanics and Geotechnical Engineering (ISSMGE- 15ARC), 9 to 13 November 2015,Fukuoka, Japan TC217 session during the 19th Southeast Geotechnical Conference, 31 May to 3 Jun 2016, Kuala Lumpur, Malaysia TC217 session during the 19th ICSMGE, 17-22 September 2017, Seoul, Korea (if accepted)

Objective 4: Industry Links

Geotechnical engineering in land reclamation has a unique role to respond to these demands in coastal development. Geotechnical engineers have to develop innovative technologies for land reclamation and coastal structures such as quays, seawalls, and revetments, in consideration of environment-friendly recycled/reused material and construction methods to achieve minimal environmental impact. Also, the engineers have to develop innovative ideas to preserve/restore rich biodiversity in coastal regions. The development and conservation technologies in land reclamation need to collaboratively work together to prevent from disorderly coastal land development.
