Groundwater Level Trends in the Vietnamese Mekong Delta, 1996-2017

22 years of groundwater level data from 1996 to 2017, comprising 88 time series collected at 27 national stations across the Vietnamese Mekong Delta. The dataset was created by Nguyen Le Duy from the GFZ Helmholtz Centre for Geosciences to analyze trends, memory effects, and response times between surface and groundwater. It likely contains measurements from shallow and deep aquifers, including Holocene, Pliocene, and Miocene layers.

Use Cases

• Trend analysis of groundwater level decline based on reported rates of 0.01-0.55 m/year across different aquifers
• Modeling aquifer memory effects based on described variations by geographical location and aquifer depth
• Estimating surface water-groundwater response times based on factors like groundwater depth and seasonal variability
• Assessing groundwater recharge potential based on the described connection between shallow aquifers and surface water

Strengths

• Covers a 22-year time span from 1996 to 2017
• Includes 88 time series of groundwater levels from 27 monitoring stations
• Analysis distinguishes between multiple aquifer types (e.g., Holocene, Pliocene, Miocene)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Last update date is unknown; freshness unverified
