SP2b: Characterization of suspended particles in the Seo Ho river and their influence on the hydroabrasion of pumps and concrete structures and the water quality


Subproject 2b is integrated in workpackage 3 (WP3) “water quality”. Within the previous project KaWaTech we were able to show, that the suspension load in the inflow of the hydroelectric power plant Seo Ho in northern Vietnam strongly fluctuates partly reaching extreme values mainly due to heavy precipitation events. Thus, it leads to hydroabrasion of pumps and concrete structures and negatively influences the water quality. Therefore, within KaWaTech Solutions SP2b is focussing on the detailed analysis of the suspended particles:


  • Monitoring the temporal and spatial variability of the suspension load
  • Characterization of the geochemistry/mineralogy, surface quality and grain size distribution of suspended particles depending on variable discharge regimes
  • Evaluation of the hydroabrasion potential of suspended particles and their role in pollutant transport
  • Provenance analysis of suspended particles
