Exploring Environmental Sustainability Research Using Experimental Methods -Taking the Vegetated Swales Facility

Due to the impact of climate change, the accompanying disasters affect the operation of the world. In addition, the development of urbanization has also increased the frequency of disasters. Therefore, the United Nations has established the Sustainable Development Goals (SDGs) to guide the global joint efforts towards sustainable goals. Vegetated Swales are a ubiquitous and growing green storm water type, primarily Low Impact Development (LID) that attenuates peak flow, reduces storm water volume, and treats storm water. Aiming at environmental factors, the research in this paper mainly uses the innovative method of low-impact development, using Vegetated Swales to reduce surface runoff and store The role of water. This study mainly uses the method of Laboratory experiment to simulate the surface runoff caused by urbanization floods, and uses Vegetated Swales to reduce the surface runoff and increase the water permeability. In the experiment, the 5-year, 25-year, and 50-year frequency floods were used as the inflow flow. The common grass species-Paspalum conjugatum Berg. was used as the test species, and the test slopes is 1%. The results show that, from the test data, with a slope of 1% and a 5-year frequency flood;25-year frequency flood; 50-year frequency flood the water retention capacity is 6.01%、5.78%、2.35%, and the flood peak value is reduced by 3.45%、2.5%、3.3%. The low-impact development of Vegetated Swales facilities in the initial stage of establishment can be used as a reference for flood treatment.
