Abstract: Gravel bars play important ecological roles in rivers, specifically in retaining organic matter filtered from surface waters making it available for utilization by stream biota as energy resources with consequent benefits to water quality and the self-purification capacity of the river. Nutrient cycling and organic matter transformation within the hyporheic zone of the gravel bars are mediated mainly by a diverse group of microorganisms. It is important to characterize the impact of microbial biodiversity on the water purification services of restored in-channel gravel bars in the Trinity River to assess as to how and to what extent the biodiversity in the hyporheic zones contributes to riverine ecosystem functioning and resilience. In this study, metagenomic analysis will be used to identify the microbial community, and assess microbial diversity between the down-and up-welling zone communities in the sediments of the restored gravel bars.
