Developing An Integrated Model For Analyzing And Predicting Deli River Water Quality Located In Medan City, Indonesia

Abstract

Rivers are an essential component of the environment as many people depend on their sustainable use. Rivers, however, are strongly threat under many different pollutants which include conventional pollutants. This paper addresses a mathematical model to predict the water quality of the Deli River as raw water for clean water in Medan City; it is a simple dynamic water quality model.Predictions of the availability of clean water from Deli River water are made for the growing population of Medan to manage the Deli River water quantity. The disposal of waste due to human activities, the formation of sediment due to changes in land use that enter the Deli River, and the physical properties of the Deli River all contribute to changes in the Deli River's quality and quantity/discharge. The model can forecast changes in the Deli River's combined quality and quantity. This model can serve as a foundation for Deli River Management Planning.
