Abstract:
Abstract. Total subsidence in deltaic areas is the cumulative effect of a
range of driving mechanisms, both natural and anthropogenic. The populous
and low-lying Vietnamese Mekong delta is facing accelerating subsidence
rates and effective mitigation strategies are urgently needed to save-guard
the future sustainability of the delta. This paper gathers results from
existing measurements and estimates of subsidence in the Mekong delta and
presents new, delta-wide datasets of PSI observations of vertical velocity
from 2014–2019. We describe the practical application of this new data in
ongoing projects in Vietnam and outline a planned approach to determine
depth-dependent subsidence rates, using this new dataset in combination with
field surveys and physics-based numerical models, to advance towards
improved quantitation of the contributions of individual subsidence
mechanisms.
