Analysis of flood modeling scenarios conducted on the simulation of urban drainage systems in Ambon city based on mathematical equations finite difference method which allows analyzing the water depth and flowing rate as a function of space and time. In order to study the propagation of flooding in the drainage channel with the 1D model of Saint Venant hydrodynamic equations are approximated by explicit MacCormack numerical method which is used as a simulation model. Numerical solution with MacCormack discretization technique on the parameters that influence the system can provide stable and final results that can be trusted. The purpose of this model is that it can reduce the volume of puddles on the local channel of drainage system area.
