Malaysia is one of the countries that experience a tropical climate with an abundant amount of rainfall. However, this large amount of rainfall paired up with rampant development has increased the severity and frequency of floods occurring in the nation. This research investigates the utilisation of a hydrological model to assess the effects of urbanisation on the river flow regime. The software used to develop the hydrological model for this research is the MIKE 11 Nedbør-Afstrømnings-Model or better known as MIKE 11 NAM. Urban development is captured by developing runoff coefficients with land use and land cover (LULC) data. The applicability of Landsat-8 satellite images in determining LULC is also explored within this research. In addition, future development scenarios are developed based on the rate of urbanisation within the Sungai Selangor catchment. The results show that the MIKE 11 NAM software captured the river flow regime of the study site relatively well, with overall performance criteria score for the coefficient of determination, \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\text{r}}^{2}$$\end{document} = 0.7 and Nash- Sutcliffe efficiency, CE = 0.6. Landsat-8 satellite images can estimate the rate of urbanisation within the study area. The runoff coefficients developed from the LULC data improved the overall performance criteria score. Lastly, the increase of developed areas in the expanse of forest area caused a sharp increase in the value of the runoff coefficient.
