Bioswales: Green Alternative for Storm Water Management & Flash Flooding Srishti Chavan Dept. of Civil Engineering, Vishwakarma Institute of Information Technology, Pune, Maharashtra, India. ---------------------------------------------------------------------***---------------------------------------------------------------------
Abstract - Flash flooding and storm water management are
water pollution, and habitat destruction. Traditional storm water systems are frequently insufficient to absorb and treat all surplus water runoff, resulting in flooding in diverse urban areas. Modern storm water management measures, on the other hand, have yet to be adopted. This study believes that using bioswales as green infrastructure components could considerably improve storm water management. As a result, this study explores the key urban design concepts of bioswales, investigates typical urban environments that utilize these green infrastructure elements, and evaluates the feasibility of their application in urban areas.
two of major concerns faced in urban settlements in relation with water channeling and management. As the requirement of land will keep on increasing, more land will be used for construction and paving thus making it impervious. This will lead to comparatively less surface area on the ground for percolation of water. Urbanization also causes pollution of storm water as it passes through the city to nearest water body by gravitational force. This degrades the quality as well as quantity of storm water that percolates into the ground water table. The purpose of this paper is to explore the concept of bioswales and how they can be effectively used to percolate maximum pure storm water in the water table. In general, we can say that bioswales are effective in removing water pollutants in urban areas. Bioswales are very sustainable, cost effective, environmentally friendly and easy to construct. They are an excellent example of green infrastructure.

Key Words: bioswales, storm water management, vegetated swales, green infrastructure, water harvesting structure, potential recharge
Implementing bioswales as green infrastructure features can considerably improve storm water treatment as well as the architecture of diverse urban forms, resulting in more positive environmental consequences. This report proposed some potential locations where bioswales could be used as green infrastructure to remediate storm water runoff in a residential district of the City of Ni. Vegetated swales are lowcost and appealing, and they can provide wildlife habitat as well as visual advantages. Urban regions gain long-term sustainability by including bioswales into retrofit projects and new buildings.
1.INTRODUCTION A flash flood can be defined as: “a flood that rises and falls quite rapidly with little or no advance warning, usually as a result of intense rainfall over a relatively small area”. Despite the increase in advanced technologies, society is still vulnerable to flash floods. People are exposed to higher risks as cities are expanding at an accelerated pace and economies are fueled by urbanization. Flash floods continue to claim the lives of many people all around the world. They also cause damage to property and infrastructure and incur economic losses. Flash floods severely affect the surrounding environment. Nowadays, there is a strong demand for land for buildings, along with agricultural land and sites for various industrial projects. The land that is used for urbanization and industrialization has impervious surface. This leads to decrease in the land surface for surface runoff and water channeling in the urban areas.
2) PERFORMANCE OF TWO BIOSWALES ON URBAN RUNOFF MANAGEMENT (Qingfu Xiao, E. Gregory McPherson, Qi Zhang, Xinlei Ge and Randy Dahlgren) This study looked at the effectiveness of two bioswales in Davis, California, eight years after they were built. The treatment bioswale was 9 m 1 m 1 m in length, width, and depth. The native loam soil was replaced with an engineered soil mix (75% native lava rock and 25% loam soil). After eight years, the bioswale with estimated soil mixtures was operating at full capacity. When compared to a standard control plot bioswale utilizing native soil, the bioswale using engineered soil mixes removed significantly more contaminants. The research shows that bioswales with engineered soil mixes can be quite useful in storm water management. Trees planted in engineered soil mixes
This study looks into the topic of bioswales and specifically its possible use in metropolitan areas. The development done has lasting consequences on the urban landscape, with one of the most notable elements of transition being urban densification and loss of public open space/green areas. Urban densification and increased paved surfaces have major environmental consequences, including flash flooding,
