Soft Soils Of The Tamar Basin

A brief account is given of the geomorphological history of the Tamar Basin at Launceston in Tasmania, showing how the deep sediments of that Basin have accumulated in the past and continue to accumulate at the present time. The nature of those sediments is described, with particular reference to the problems they pose for flood protection of developed suburbs, for engineering works and building construction on the flood plain, for riverside developments, and for sediment removal (dredging) and the disposal or reuse thereof. It summarises more than 65 years of the author’s accumulated experience on and about this river.
