The evaluation process of the land development project becomes complicated, as the simulation results of Fine-Scale Models (FCM) of lands proposed for development cannot be easily transferred to the watershed Coarse-Scale Models (CSM) due to parameterization problem. In this research study, a Multi-Scale Modelling (MSM) methodology was developed to minimize the difficulty in transferring the result into the different spatial scales of the models. The developed MSM methodology was tested on Ganatsekiagon Creek’s sub-watershed, simulating several scenarios. The analyses of model results show that the CSM is generating a lower Peak Flow Rate (PFR) and Flow Volume (FV) than the MSM, while the increasing level of development with BMPs leads to a rise in FV and a decrease in PFR. The comparison results of with and without BMPs show that the stormwater management ponds are effective in PFR reduction and the implementation of LID practices can be effective in FV reduction.
