Abstract

Lakes in Universitas Indonesia (UI) have severalproblems to overcome. Water quality of UI’s lakes degrades inthe last decade. One of the problems is high turbidity. Thelonger turbidity in lakes, the more dangerous the lakesenvironment life would be. So, this research focuses onsediments problem or physical assessment. The main researchaims to develop hydrodynamic and sediment transportmodelling of Agathis and Mahoni Lakes in UniversitasIndonesia. The authors want to increase the quality of water inUI’s lakes and make both Agathis and Mahoni Lakes as therepresentative preliminary model. Research design ormethodology is needed to concept the research to achieve goals.Unfortunately, research methodology has not been developedyet for this case. This paper goals to construct methodology as apreliminary study of the main research. The authors useextensive literature review to model novel methodology.Hydrodynamic and sediment transport modelling could bemodelled by Resources Modelling Associates (RMA).Hydrodynamic phenomena in fluid and sediment transportmodelling have the suitable governing equation concept withRMA’s governing equation. As a thinking result, the mainresearch would be conducted by RMA program modelling, fieldsampling, and laboratory testing. Field sampling andlaboratory could figure the amount of sediment concentrationin lakes as data input. The final simulation of this followingresearch is making sensitivity and scenario analysis to proveseveral hypotheses.
