The effect of initial concentration on the consolidation behaviour of mud: A study on lake Markermeer sediment

Land reclamations in deltaric areas provide space to meet the demand for a safe place to live and work. Sand, a traditional filling material in some locations is becoming scarcer. An alternative filling material is mud. Mud consists of clay, silt, sand, organic material, water and gas. Therefore, it is a versatile material and difficult to...

Morphodynamic optimisation study of the design of semi-permeable dams for rehabilitation of a mangrove-mud coast: A case study of the Building-with-Nature project in Demak, Indonesia

Due to the removal of mangrove forests, the coastal zone of Demak district has suffered from severe erosion. One of the proposed solutions to restore the sediment balance and encourage mangrove re-establishment, is the construction of semi-permeable dams. This study aims to optimise the design of such structures. A 2DH site-specific model was...

Consolidation be haviour of soft cohesive soils, the correlation between different scale model tests: Case study of the Marker Wadden

A group of islands will be constructed in the lake Markermeer to act as nature reserve for birds, called the Marker Wadden. These islands will be constructed out of soft clay, dredged from the bottom of the lake. Building with soft cohesive soils, also referred to as mud, is still a largely unknown territory. Traditionally, sand is used for land...

The effect of pH and the solids composition on the settling and self-weight consolidation of mud

A demand to use mud as fill material for land reclamations has emerged over the past years. Such reclamations start with pumping a muddy suspension into an area enclosed by dikes. The particles in suspension then settle to form a mud layer, so that the supernatant can be removed. This filling process may be repeated several times to completely...
