Methodology of sensitive planning and design of stormwater drainage system on urban watersheds

Abstract

For sustainable stormwater management planning in urban areas a hierarchical approach is needed, from planning on the watershed level, to the implementation on the location level, so a comprehensive approach to planning and designing the improvement of stormwater drainage could be provided with a goal of developing a drainage system, which balances the goals of drainage efficiency maximization and minimizing the negative effects on the environment. But the watershed level, which is relevant to urban hydrology, is almost always ignored while developing stormwater management plans. This paper shows a methodology oriented towards studying of the morphology of the urban watershed in the context of sustainable stormwater management, which consist of five steps and intends to help city planners and engineers choose the right location and make a selection of the best stormwater management practices when defining a sustainable decentralized stormwater management plan.
