Water Stops : Study on New Type of Flood Control System

The purpose of this study is to test a new type of flood control system that can effectively be utilized to respond to and resolve urban floods. Floods in urban areas lead to particular consequences, because the modification of the land surface during urbanization produces changes in the magnitude of runoff processes. Within the urban fabric, floods lead to increased runoff causing drainage control issues. Existing flood control mechanisms are the primary insertions that prevent inundation by the river. Unfortunately, current large scale systems are inappropri-ate to prevent flooding that leads to excessive urban runoff. Furthermore, the urban flooding occurs at unpredict-able times locations within the city, posing further problems and demanding solutions.

The project proposes that decentralized small reservoirs be placed in numerous locations throughout the city. The localized reservoirs that span the city can react immediately to unexpected floods and manage runoff. In order for these reservoirs to be more adaptive to the local district of installation, the scale of the reservoirs has to be reduced. Also, for the purposes of sustainable utilization of the flood controller, passive ways of using the system have been thoroughly explored. Lastly and most importantly, these localized small-scale reservoirs are in-tegrated with existing programs in order to capitalize on the newly inserted infrastructure and the collected water within the reservoirs. Thus, the design of a new flood control system that is more reactive and imbued with bus stops, one of the most distributed typologies, is the product of this proposal
