Characteristics of Sediment in Bung Binh Thien Reservoir, An Giang Province, Vietnam

Abstract

This study was conducted from March to September 2019 to evaluate
the quality of sediment in Bung Binh Thien through the indicators of
organic matter, total nitrogen, and total phosphorus by collecting the
sediment samples in the outside, inlet, middle, and end areas of the
reservoir in the dry and rainy seasons. The findings revealed that the
quality of sediment in the area of Bung Binh Thien was spatially and
temporally fluctuated. In the dry season, the content of organic
matter, total nitrogen, total phosphorus fluctuated respectively from
1.04 to 5.35%; 0.06-0.35% and 0.036-0.076% which were higher than
those in the rainy season with the corresponding values were 1.51-
4.65%; 0.10-0.28% and 0.042-0.072%, respectively. The nutrients in
the sediment inside the reservoir was relatively higher than those in
the outside area. There was a strong correlation between total
nitrogen, total phosphorus and organic matter in the study area. This
partially reflected the impact of living activities and production of the
surrounding community on environmental quality in the area of Bung
Binh Thien.
