Abstract
As airport construction competes for land, more and more new developments in volve major land form changes, from the channel modifications on the River Bollin at Manchester Airport to the seaward expansion of runways at Sydney and Beirut and the enlargement or total creation of islands at Chek Lap Kok Airport, Hong Kong and Kansai International Airport in Osaka Bay, Japan. The quantities of material in volved are large, 307Mm3 of material being moved for Chep Lap Kok Airport and 13Mm3 will be needed to fill the area required for a new runway at Seattle-Tacoma International Airport. Both the land form changes and the excavation and filling of materials produce profound geomorphic changes. In some cases the new configurations are unstable and may need to be rectified by further engineering work. Greater sustainability is achieved when recycled material is used for filling, such as the use of some 2Mm3 of material dredged as a part of normal navigation channel maintenance
