The Bhumibol Dam on Ping River, Thailand, was constructed in 1964 to provide water for irrigation, hydroelectric power generation, flood mitigation, fisheries, and saltwater intrusion control the Great Chao Phraya River basin. Many studies, carried out near basin outlet, have suggested that dam impounds significant sediment, resulting shoreline retreat of Delta. In this study, impact damming se...

Abstract Theoretical and empirical equations have previously been proposed to compute the sediment trap efficiency of a reservoir. The were developed by analyzing limited amount field data for reservoirs in selected areas; thus, their suitability is restricted regions with similar hydrological characteristics. In this study, trap-efficiency equation, which accounts dynamic behavior sedimentatio...

This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract The average depth in the ocean at which the majority of sinking organic matter particles remineralise is a fundamental parameter in the oceans role in regulating atmospheric CO 2. Observed spatial patterns in sinking fluxes and relationsh...

Sinking particles formed in the photic zone and moving vertically through the water column are a main mechanism for nutrient transport to the deep ocean, and a key component of the biological carbon pump. The particles appear to be processed by a microbial community substantially different from the surrounding waters. Single cell genomics and metagenomics were employed to describe the successio...
