Ty Sok from the Institute of Technology of Cambodia analyzed long-term monitoring data from 1993 to 2018 to estimate sediment loads in the Tonle Sap and Lower Mekong Rivers. The dataset includes annual sediment estimates for three monitoring stations, showing a reduction in sediment transport to the Mekong delta. The analysis indicates a shift in the Tonle Sap Lake from a sediment source to a sink after 2001.
Use Cases
- Modeling sediment flux changes based on long-term monitoring data from 1993-2018
- Assessing the impact of upstream dam construction on downstream sediment loads
- Analyzing the sediment linkage between Tonle Sap Lake and the Mekong River based on seasonally reversing flow
- Estimating the effects of sediment trapping and sand mining on delta evolution
Strengths
- Data spans a 25-year period from 1993 to 2018
- Includes estimates from three specific monitoring stations (Kratie, Chroy Changvar, Prek Kdam)
- Provides quantified annual sediment loads with reported uncertainty (e.g., 72±38 Mt/yr)
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
