Abstract
In addition to river water pollution caused by human activity and industrial activity, also due to influence of natural activities such as volcanic activity that has volcanic ash and cold lava cause river pollution in river water at the same deposition. Besides of community activities Surabaya living along the Brantas River flow contributes to making soil erosion along the river, pollution and deposition also occurs due to discharge of industrial waste or household waste. This was strengthened with the data from the Ministry of Environment, Sindo’s magazine on Nopember 7th 2013, "The total number of industries in East Java that has the potential to pollute the river there are about 1,004 industries, of that number as many as 483 industries located along the Watershed (DAS) Brantas river Surabaya and capacity pollution load 35 tons of organic waste a day, but the fact more than 70 tons of organic waste a day ". It becomes negative news for the citizens of Surabaya so that the public and the government of Surabaya more careful in taking precaution because almost 96% of the water supply Surabaya Kali is a tributary of the Brantas river used to PDAM Surabaya, so according to its function, the water must be maintained the quality of the water and do monitoring in order to remain decent for use. In this research focuses on the modeling of pollutant dispersion and sedimentation patterns in the confluence of two rivers by combining elements of hydrodynamics using Finite Volume Method QUICK scheme (upwind Quadratic Interpolation Convective Kinematics) so that the results of this research are expected to helping the parties involved in maintaining the quality of the Brantas River Surabaya to remain fit for consumption and reduce silting of the river.
