Modelling the effects of industrial discharged waters to Degirmendere River (South Eastern Black Sea)

Abstract

<span style="color:black;mso-bidi-language:HI">In this study, modeling the effect of discharge waters from various industrial establishments located along the Degirmendere basin in Trabzon was investigated. Discharges from industrial establishments directly influence the water quality of the Degirmendere River, which is also influenced by inputs resulting from sewage, industrial processes, and agricultural run-off water discharge. Wastewaters are often discharged continuously into this river. The organic compounds found in the water are utilized by aquatic micro organisms and consequently reduce th<span style="color:#1D1D1D;mso-bidi-language: HI">e <span style="color:black;mso-bidi-language:HI">dissolved oxygen (DO) concentration in the river. Models of DO profiles are useful in predicting possible consequences of additional river discharges or aeration strategies on the river.
