The increasing of urban development and the decreasing of public awareness to environment promote flood every year for urban cities. Several lakes or ponds are scarified due to both urban development and land filling. Bad habit of society to throw garbage to the lakes affects the society to think that the economic value of lakes could be increased by filling them with land. These lead to make the lakes become vulnerable to sedimentation from urban activities. Universitas Indonesia as educational institution starts to develop how to manage sedimentation by hydrodynamics and sediment transport modelling. The research uses Resources Modelling Associates (RMA) program to run the model and Agathis Lake as study area to perform the simulation. It is expected that the program output data could represent the field data, so the validation method should be conducted. The issue to validate the data would be problematic if simulation factors data could not accommodate real-world observed data. This study aims to employ Galerkin method to understand finite element method in Resources Modelling Associates Program (RMA) in order to avoid black box when using it and to conduct field study to perform calibration method of sediment transport modelling in the study area, Agathis Lake that is located in Universitas Indonesia.
