Pollution Load Capacity Assessment by Utilizing QUAL2E Modelling: A Case Study of the Rambut River, Indonesia

Abstract

As the number of population and intensity of activities around the river increased, it is possible that the water quality in the river will be negatively impacted. River Rambut, which located in Pemalang and Tegal, Indonesia, has an important role as a water source in both areas. However, this demand is not accompanied by the availability of river capacity information yet. Five points from different segments along the upstream and downstream of Rambut River was assessed with QUAL2E model. There were four different parameters in the research, e.g., BOD, fecal coliform, nitrite, and nitrate. The results showed that some segments were not complied with the minimum requirements by the local government. Additionally, the BOD and fecal coliform value were predicted to be increased in 2023 due to higher population number living near the river. The values for all parameters were fluctuated between the different segments.
