The objective of this study was to evaluate the treatment efficiency of a gravel contact oxidation treatment system which was newly constructed under the riverbed of Nan-men Stream located at the Shin Chu City of Taiwan. The influent and effluent water samples were taken periodically for the analyses of pH, temperature, dissolved oxygen, total suspended solids, five-day biological oxygen demand...

in general, estuaries may be classified variously according to inlet dynamics, geomorphology orwhether they are tide or river dominated or, on a combination of all three factors. in kwazulu-natal (kzn),south africa, the four recognised estuary types are temporary opened-closed estuaries (toces), permanently opened estuaries, estuarine lakes and river mouths. since physico-chemical parameters ar...

Intensifying land use and accelerated erosion has resulted in increased delivery deposition of fine terrestrially derived sediment to coastal ecosystems, increasing mud content estuarine ecosystems. This change the sedimentary environment is known have negative consequences for ecosystem functioning. Yet indirect cyclical relationships between species are rarely investigated, despite being cruc...

Planktonic microorganisms in aquatic ecosystems form complex assemblages of highly interactive taxa and play key roles biogeochemical cycles. However, the microbial interactions within bacterial microeukaryotic communities, mechanisms underpinning responses abundant rare to environmental disturbances river estuary remain unknown. Here, 16S 18S rRNA gene sequencing were used investigate composit...

Subaqueous dredging is a management activity undertaken globally to improve navigation, remove contaminants, mitigate flood risk and/or generate aggregate. Water Injection Dredging (WID) hydrodynamic technique involving the turbation and downstream displacement of fine sediments using vessel-mounted water jets. Despite being widely applied internationally, environmental ecological effects WID a...

Abstract Human intervention and climate change jointly influence the functions dynamics of marine ecosystems. Studying impacts human on ecosystem is challenging. Unlike experimental studies, research natural systems not amendable at scale time, space, biology. With confounding factors well balanced for two adjacent subtropical estuaries except urbanized disturbances, we conducted modelling usin...

the johor strait is an estuarine system located on the coast of the state of johor in malaysia.the western part of johor strait is a shallow estuarine located between causeway and pulai river. ahydrodynamic model was calibrated based on the environmental fluid dynamic code (efdc) from 4th to 17th of october, 2009. in this calibration, the efdc hydrodynamic model was configured to simulate time ...
