Monitoring land subsidence in Yangon, Myanmar using Sentinel-1 persistent scatterer interferometry and assessment of driving mechanisms

Inhabitants and ecosystems in delta areas are becoming increasingly vulnerable to the effects of subsidence, caused by anthropogenic activities. Yangon is a city on the periphery of the Irrawaddy delta in Myanmar where little is known about the true extent of this hazard, while its effects can potentially harm millions of its inhabitants. This...

Siltation Mitigation In A Data Poor Environment: Assessing The Influence Of A Sluice On Siltation Rates In The Nga Moe Yeik Creek, Yangon

The typically mild slopes of the muddy coastline in the south of Myanmar, enable the tide to propagate deep into the mainland, carrying muddy and saline water. The Nga Moe Yeik Creek (a tributary of the Yangon River) is closed off at the upstream end during the dry season and is subject to high siltation rates. Extensive dredging is necessary to...

Sinking Yangon: Detection of subsidence caused by groundwater extraction using SAR interferometry and PSI time-series analysis for Sentinel-1 data

Inhabitants and ecosystems in delta areas are becoming increasingly vulnerable to the effects of subsidence, triggered both by natural causes and anthropogenic causes. Yangon is a city in the Irrawaddy delta in Myanmar where little is known about the true extent of this hazard, while its effects can potentially harm millions of its inhabitants....

Feasibility of Velocity Measurements by a Drifter in the Yangon River

Myanmar is dealing with a large data deficit, which is in contrast with the substantial need for it. The implementation of measuring techniques to obtain hydro- and morphodynamic data is an upcoming process. Measuring velocities can be valuable for calibrating models or giving estimates of sedimentation and erosion. An example of a measuring...

Delft3D-FLOW Model of the Yangon Port Area

Large sedimentation is observed in the Yangon port area in Myanmar and this sediment is blocking the entrance channel into the port. The entrance channel is dredged intensively to keep it navigable but insight into the sedimentation processes is limited. The sedimented area rises above the water level in dry season and is known as the Inner Bar....
