The water sensitive urban design (WSUD) includes the concept of solutions that aim to manage and reuse storm water in urban areas. Combining function, aesthetics and usability, water sensitive solutions provide multiple services to the ecosystem by transforming urban landscape into a multifunctional space. Based on the principles of landscape ecology, the urban water sensitive design forms an integrative approach that combines ecological, social, economic and cultural performance. Solutions such as roof gardens and rain gardens are innovative solutions that can be implemented in urban areas during the reconstruction or early planning of the city, for the treatment and collection of storm water from roofs and roads. Roofs as part of an urban water cycle can be designed as blue roofs for temporary water retention or as green roofs with additional contents in the form of vegetative cover, while rain gardens as systems that absorb and filter storm water, thereby reducing the amount of rainfall and contaminants can be implemented in various urban city centers. After the outflow from impermeable surfaces (roofs, streets, parkings), storm water can contain high concentrations of heavy metals such as copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd) and other pollutants. Water sensitive urban design can improve public awareness of the management of urban storm water by making it visible in the design of public and private open spaces in the city. Collecting rainwater from hard, impermeable surfaces, can reduce the risk of flooding and keep streets safe as well as increase the quality of surface water and renewal of groundwater.
This paper focuses on the development and application of multifunctional, ecological, water sensitive solutions in landscape architecture as recommendations for designers from widely applied international standards and guidelines with defining optimal modern innovative solutions for rainwater retention or underground water infiltration, in the reconstruction and planning of the city, such as rain gardens and roof gardens. The paper will also provide suggestions for applying water sensitive solutions, roof gardens and rain gardens, for the city of Novi Sad as an example of the city with problems of flooding, both for individual locations that are flooded during heavy rains, as well as for general future planning of the city.
