Geochemical Characteristics of Water, Sediments and Suspended Solids in Sibuti River Estuary and Its Potential Effect on the Miri-Sibuti Coral Reefs

Abstract

The hydrological regime of the Sibuti River is mainly controlled by rainfall associated with Pacific Decadal Oscillation (PDO) and discharging into SW part of Miri coast, East Malaysia. The current study reveals that natural weathering of siliciclastic sediments coupled with deforestation and agricultural and wastewater effluents are the major sources for the geochemistry of river basin. The estuarine contaminants runoffs have minor to major influence on Miri Sibuti Coral Reefs depending on the seasonal variation.
