Abstract
In hydraulic engineering, the clogging of pores due to sedimentation, infiltration and accumulation of fine material into pores of gravel river beds is called colmation. The evolution of this process is highly complex and characterized by a high spatial and temporal variation. Moreover, various physical, chemical and biological factors are involved and interact with each other. Although, several studies examined fine sediment infiltration and accumulation in the field and in laboratories, knowledge gaps still exist regarding an adequate and detailed description of ongoing processes and their interactions. Therefore, fundamental experimental research is required to gain deeper insights into the phenomenon of colmation.
The main objective of this research is to plan, conduct and analyze laboratory experiments to investigate distinct processes that are involved in the development of colmation. The dynamics of colmation processes will be examined by measuring the impact of progressing pore occlusion using a non-destructive measuring technique that allows for the assessment of fine sediment infiltration masses at different position along a vertical profile. Based on an extensive experimental program, and in-depth analyses of the results, a unique dataset will be created to find significant correlations to describe interacting processes and parameters.
