| Abstract | In the Sta. Cruz area of Manila, Philippines, flood control and drainage system operation has yet to effectively address the inadequate performance of the system. Proper formulation of concrete, cost-effective and sustainable drainage improvement measures demands a clear understanding of the conditions and processes at work. But in Manila, possible solutions to drainage problems are identified based on inadequate information about the drainage processes and conditions. The use of a computer-based model to simulate and analyze the drainage system would provide a possibility for a more systematic and comprehensive analysis. In this study, MOUSE, a physically-based model, was used to represent a one-dimensional pipe network model simulating the urban drainage system of the Sta. Cruz area- or more specifically the Quiapo Drainage Block-of Manila. The existing drainage capacity of the system was evaluated using the MOUSE model, and a flood map for the study area for better visualization of model results was generated through the use of MIKE 11/GIS. Model results and the generated flood map have shown that the model generally overestimates the depth of flooding. Simulation results with the present MOUSE model for the study area show that the drainage conduits have capacities that are inadequate for rainfall of ten (10) years return period against which they were supposedly designed for. Model simulations also show physical measures that can alleviate flooding in the area includes the installation of additional drainage pumps, and the rehabilitation and improvement of the esteros and drainage conduits through dredging and de-clogging. More detailed input about the drainage structures and the street network are needed to improve the model representation of the drainage network. To better simulate the behaviour of the system during flooding, measured data during observed flood events should be available for calibration. Flood-damage curves for Manila should be obtained to quantify the economic impacts of flooding corresponding to model results. |
