## Abstract

Analysis of velocity in the river segment is a first step in determining step efforts to solve the problems that occur scour the riverbed. Along with the development of software so rapidly is often the choice of mathematical models as a tool to obtain the behavior occurs, because in addition to its low cost. This model can cover dimensions of space and long term. Surface Water Modeling System a program to solve a mathematical model that builds on the concept of movement of water and sediment movement are mathematically solved by using the finite element method through a horizontal two-dimensional approach. This model is expected to provide satisfactory results to improve the performance of methods common approach used previously.The research location is next Brantas River Campus III UMM Malang in East Java which have problems of scouring in the river. From the analysis shows scour flow rate level is very large, with Manning entering a value n = 0,045, obtained the results of a very high speed is Maximum = 0.25 m/s and Minimum = 0.03 m/s exceeds the critical velocity for D is 0.045 50m/s, while the results obtained weir placement results for Maximum speed = 0043 m/s and Minimum = 0.010 m/s below the critical speed of the D50.
