Physical and chemical properties of bottom sediments in surface waters of Central and South Vietnam

Abstract

In this study, physical and chemical characteristics of bottom sediments in inland waters of Central and Southern Vietnam were investigated, initially according to granulometric compositions, organic matter contents, bulk densities, and natural moisture contents. The main types of sediments in rivers, lakes, reservoirs, former quarries, and ponds were then identified, and similarities between of physical and chemical properties were identified between bottom sediments from water bodies of Vietnam and those from the Volga cascade reservoirs. Moreover, we show common dependencies in the formation of bottom sediments in reservoirs from humid, arid, and tropical monsoon climates.
