Maccaferri riverbank protection solutions in Bangladesh
Maccaferri offers a wide range of riverbank erosion protection solutions that can be used in Bangladesh where bank erosion is an endemic and recurrent natural hazard.
Bangladesh, due toâŊitsâŊgeographical location, is severely affected byâŊriverbank erosion problems. Maccaferri offers a graded, logical range of hydraulic erosion protection techniquesâŊ(such asâŊMacmatÂŪ R,âŊReno MattressÂŪ, Gabion,âŊTerrameshÂŪâŊsystem)âŊso that the level of intervention is appropriate to the erosion risk faced.Â
Bangladesh is located in the lower part of the delta where the worldâs three largest rivers the Ganges, the Brahmaputra and the Meghna meet the sea. Due to this geographical location, the rivers of Bangladesh are morphologically very active which is evident from the continuous widespread bank erosion, channel shifting and sedimentation processes. Riverbank erosion problem in Bangladesh is a regular phenomenon and the country is constantly facing huge socio-economic problems. Bangladesh, on average, loses moreâŊthan 8,000 ha of land annually due to bank erosion.âŊDespite the fact that a large number of riverbank protective works have been implemented only a few of them have been efficient.âŊâŊâŊÂ
Longitudinal structuresâŊalong the rivers are built to protect the river against erosion during flood, to stabilize riverbank, and to protect infrastructures (villages, roads, railways, highways, airports, etc.).âŊâŊÂ
Maccaferri offers two main groups of solutions: revetments, which role is to protect riverbanks from scour generated by river action, and retaining walls, where the need of scour protection is combined with the soil retaining function. Revetments are usually made by Reno MattressesÂŪâŊand MacmatÂŪâŊR, while Retaining structures may use Gabions, TerrameshÂŪâŊSystem or Green TerrameshÂŪ.âŊÂ
MacmatÂŪ RâŊis a geomat made from a three-dimensional matrix of UV stabilized, nondegradable synthetic fibres, heat bonded where they cross, extruded onto a double twisted steel woven mesh.âŊâŊÂ
Reno MattressesÂŪâŊare cages, engineered from double twisted hexagonal woven steel wire mesh. Their main characteristic is a large surface area and a small height.âŊÂ
GabionsâŊare rectangular prism shaped elements which can be divided into cells by the insertion of diaphragms.âŊâŊÂ
TerrameshâŊis a modular system used for soil reinforcement applications which can be with a gabion facing (TerrameshÂŪ System) or a vegetated one (Green TerrameshÂŪ).âŊÂ
