Planning layers to inform the design, location and environmental and social assessment of future river training works in the Ayeyarwady
The Ayeyarwady is Myanmar’s largest river system. Measuring the length of the country, it is both a crucial source of livelihoods and a vital commercial waterway. Along the river, many are dependent on the fertile riverbank fields and gardens, its fisheries, water for crop irrigation and for transportation. The river is also a source of culture with countless religious and historical monuments lining its banks and a historic channel that takes goods across the country.
The development of inland waterway transport (IWT) along this river is seen as integral to the economic development of Myanmar. To improve IWT along priority stretches of the river, and to design a cost-effective, environmentally and socially acceptable strategy for managing the full length of the navigation channel the Ayeyarwady Integrated River Basin Management Project (AIRBMP) was launched.
An Environmental and Social Assessment (ESA) of development of a 160 km stretch of river between Mandalay and Nyaung Oo has now been completed. The purpose of the development is to improve future navigation, allowing for 1,000 deadweight tonnage (DWT) barges to navigate up the river from Yangon to Mandalay during the dry season. Civil works may include closing subsidiary low-water channels with bunds and placement of flow-guiding structures such as groynes and embankments. Other activities include dredging, elimination of obstacles, bank and bed protection.
The objective of the ESA was to provide information to inform the design and detailed Environmental and Social Impact Assessment (ESIA) of future navigation enhancement interventions for this area, as such interventions may cause adverse environmental and social impacts from changes to aquatic and riparian habitats in response to changes in river morphology, flow, depth, sediment flux, water quality and turbidity. Transport and disposal of dredged materials may also have […]
