The purpose of this classroom video is to hear student ideas about the urban water cycle and to think about key concepts you would teach to your students. The cloudburst management plan has the potential to support the city’s aim to become more green, liveable, and sustainable. All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN), In these high density areas, water efficiency measures result in the highest savings in water volume, but do not cause significant problems in the technical performance of the potable water supply network. As they do this, write each group's hypothesis on the classroom board. Thanks for your feedback! Example questions: What do you think will happen to runoff flow if it rains really hard? groundwater flow: A lateral or horizontal flow of water beneath the ground surface. While public spaces are among the most vulnerable areas to climatic hazards, they entail relevant characteristics for adaptation efforts. Unit, Middle School Nest bottle #2 into bottle #1. Pump stations prevent backwater effects from urban streams and safely drain rainwater in urban areas. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff. The results show that if the cloudburst system is exploited to discharge runoff from selected areas that are disconnected from the combined sewer system, then the plan leads to multiple benefits. Thanks for your feedback! Urban water cycle. Divide the class into groups of three or four students each. Authors may use MDPI's Coordinated strategies that integrate inter-, extra-, and intra-boundary activities, framed through collaborative scenario building and the use of interactive modelling platforms, may offer ways to enhance the use and utility of scientific knowledge (and its tools) to better support water resources management, policy and planning decisions, thus promoting a more cohesive relationship between science and policy. Risk assessments play a pivotal role in the take-up of new and unfamiliar water projects, acting as a decision-making tool for business cases. Urbanization has increased the required capacity of centralized reservoirs and drainage pumps; yet, their respective designs are based on the runoff of the target watershed at the time of design. Refer to the associated lesson for an extensive background on both the natural water cycle and the urban "stormwater" water cycle. Then ask groups to share another hypothesis, skipping to the next one if the same one has already been provided by another group. In this work, an approach which couples the UrbanBEATS model for the planning of decentralised strategies together with a water supply modelling approach is developed and applied to a demonstration case. Before releasing students into the group work, ask them how they are going to conduct themselves and what is expected from them. ), How have people impacted the natural water cycle? Today, we will use models to gain a better understanding of the flow of water through both cycles. Remove the foil barrier and quickly pour 2 liters of water into the top of the natural water cycle model again so that students can see the different interactions. What do you think will happen to runoff flow if it rains really hard? Bottle #4: Insert the end of the tubing from bottle #3 into its neck. (Possible answer: Because of the existence of buildings, roads and parking lots.). We demonstrated the methodology on scenarios representing sequential enhancements of the cloudburst management plan for a district that has been appointed to become the first climate resilient neighbourhood in Copenhagen. As a class, discuss the results of all the experiments and come to a consensus on a conclusion that can be drawn from the experimental results. As students begin to describe parts of the water cycle, write them on the board in two columns, one for parts of the water cycle that are more associated with the production of rain and the other for parts of the water cycle that have to do with where the rain goes after it hits the ground. Follow-up by asking: What are you thinking when you say "even more runoff"? The City of Sydney is constructing more than 21,000 square metres of street biofilter units (raingardens) in terms of their Decentralised Water Master Plan (DWMP), for improving the quality of stormwater runoff to Port Jackson, the Cooks River, and the historical Botany Bay. Therefore, this study developed a GIS routine to generate synthetic storm drain inlet locations for the purpose of urban flood modelling. The statements, opinions and data contained in the journals are solely As a class, go through each hypothesis and its steps to obtain a consensus on the best approach for testing each hypothesis. The cloudburst management plan has the potential to support the city’s aim to become more green, liveable, and sustainable. Consequently, this article presents the simulation and evaluation of implementing infrastructure options (stormwater harvesting, reuse of industrial waters, water-saving technology in residential sectors, and reuse of water from washing machines) for managing urban water in two urban catchments (Fucha and Tunjuelo) in Bogotá, Colombia, over three periods: baseline, 10 years, and 20 years. This stormwater makes its way into water treatment facilities that provides drinking water for our homes, schools and communities. (Grades C. Record the amount (volume) of runoff and groundwater flow. With the Students—Natural Water Cycle Model Experimentation. An accurate assessment of the future water supply/demand balance is crucial to capital investment for water infrastructure. Students apply their understanding of the natural water cycle and the urban "stormwater" water cycle, as well as the processes involved in both cycles to hypothesize how the flow of water is affected by altering precipitation. Decide and/or prepare this impervious surface material, perhaps a piece of aluminum foil (see other suggestions in the Materials List) such that it can be easily added and removed. impervious surface: A surface that water can NOT pass through. (Grade MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. We use cookies on our website to ensure you get the best experience. This bottle collects the runoff flow. These strategies were evaluated under four population growth scenarios (very fast, fast, moderate and slow growths) by using several Key Performance Indicators (KPI’s) including water demand, leakage levels, total costs, energy consumption, rainwater delivered and greywater recycled. water reservoirs. Further insight is gained by highlighting the wide spectrum of uses and utilities existing in practice, suggesting that such ‘boundary organisations’ facilitate interactions and exchanges that give added value to scientific knowledge. 6 - Operation of the gates and drainage pumps is based on the water level in the connected centralized reservoirs. Deadline for manuscript submissions: closed (30 September 2017). A qualitative study based on empirical analysis offers a novel approach to exploring key factors. Have each group also provide the list of steps for testing their hypotheses; write these steps on the board also. ). Go around to each pair and ask: How does the water get from rainfall to the river/lake/groundwater? pervious surface: A surface that water can pass through. Urban areas are currently experiencing rapid growth, which brings with it increases in the population, the expansion of impervious surfaces, and an overall jump in the environmental and hydrological impact. Replacing the entire centralized infrastructure is very difficult within the existing environmental and economic constraints. Natural and Urban "Stormwater" Water Cycle Models. (The intent of the teacher-student interaction is to assess students' existing knowledge and any misconceptions that they may have coming into the activity, and to address any misconceptions at this point so that students attain an accurate understanding of the natural water cycle.).
