In the world a lot of researches on urban flooding and drainage have been done and a lot of progresses have been achieved. In Iran, especially in recent decades, researches in this direction have been drown at many attentions. In the past, in mertopolian of Iran such as Isfahan, stormwater structures, with the aim of control and disposal of surface runoff were designed and constructed. That's why, by revealing the other demands in the areas of environment, social and political decision-makers need to know and comprehensive information to understand and operate in their decisions. In Isfahan, using of the system for water wells, marginal landscape beside streets and guided to the surface duct is three traditional approaches to deal with stormwater. In this thesis, the system of wells was evaluated. For evaluating of this system the temporal distribution of precipitation, with Pilgrim method, for Isfahan rain gauge stations was extracted. Using the results of previous research on the subject of climate change, and daily precipitation amounts, curve of the intensity, duration and frequency for the future were built on two predicted scenarios. Rainfall-runoff model for urban catchments showed, wells systems in the Isfahan metropolitan could store, about 28 percent of the precipitation. Also a part of it infiltrate gradually to the groundwater. The results showed, the system with the existing conditions, is not a sustainable management of stormwater. The reason is the inadequacy of social indicators. There are uneven surface of pathways, stench, creating a gathering place for insects and disrupting traffic when needed to repair. So the structural and non-structural policies dealing with the system studied. It was also found, the climate change, have not devastating effects or a significant positive effects on the system.
