Urban Drainage and Watermanagement

(View Complete Item Description)

The lectures will discuss characteristics of urban water flows, hydraulics, hydrology and how to apply knowledge of these phenomena to the design and analysis of urban water systems. Integration of various scientific disciplines and technological and practical approaches is a central theme in this course. Students will design an urban drainage system for a real case in the Netherlands or abroad using the Rational Method. They will use this design as input for a hydrodynamic computer model and perform model calculations for various conditions to check the performance of the designed system and improve where needed. They will prepare a written report of their data, design choices and results and present main results in a plenary session that concludes the lecture series.

Dams

(View Complete Item Description)

Through eight lessons, students are introduced to many facets of dams, including their basic components, the common types (all designed to resist strong forces), their primary benefits (electricity generation, water supply, flood control, irrigation, recreation), and their importance (historically, currently and globally). Through an introduction to kinetic and potential energy, students come to understand how dams generate electricity. They learn about the structure, function and purpose of locks, which involves an introduction to Pascal's law, water pressure and gravity. Other lessons introduce students to common environmental impacts of dams and the engineering approaches to address them. They learn about the life cycle of salmon and the many engineered dam structures that aid in their river passage, as they think of their own methods and devices that could help fish migrate past dams. Students learn how dams and reservoirs become part of the Earth's hydrologic cycle, focusing on the role of evaporation. To conclude, students learn that dams do not last forever; they require ongoing maintenance, occasionally fail or succumb to "old age," or are no longer needed, and are sometimes removed. Through associated hands-on activities, students track their personal water usage; use clay and plastic containers to model and test four types of dam structures; use paper cups and water to learn about water pressure and Pascal's Law; explore kinetic energy by creating their own experimental waterwheel from two-liter plastic bottles; collect and count a stream's insects to gauge its health; play an animated PowerPoint game to quiz their understanding of the salmon life cycle and fish ladders; run a weeklong experiment to measure water evaporation and graph their data; and research eight dams to find out and compare their original purposes, current status, reservoir capacity and lifespan. Woven throughout the unit is a continuing hypothetical scenario in which students act as consulting engineers with a Splash Engineering firm, assisting Thirsty County in designing a dam for Birdseye River.

Environmental Engineering

(View Complete Item Description)

In this unit, students explore the various roles of environmental engineers, including: environmental cleanup, water quality, groundwater resources, surface water and groundwater flow, water contamination, waste disposal and air pollution. Specifically, students learn about the factors that affect water quality and the conditions that enable different animals and plants to survive in their environments. Next, students learn about groundwater and how environmental engineers study groundwater to predict the distribution of surface pollution. Students also learn how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow. Additionally, students discover that the water they drink everyday comes from many different sources, including surface water and groundwater. They investigate possible scenarios of drinking water contamination and how contaminants can negatively affect the organisms that come in contact with them. Students learn about the three most common methods of waste disposal and how environmental engineers continue to develop technologies to dispose of trash. Lastly, students learn what causes air pollution and how to investigate the different pollutants that exist, such as toxic gases and particulate matter. Also, they investigate the technologies developed by engineers to reduce air pollution.

Geography 431 is designed to further understanding of the natural processes of aquatic ecosystems, management of water resources, and threats to sustaining water quantity. Develop awareness and appreciation of the perspectives about water as a precious resource, commodity, and sometimes hazard. Learn how and why water is distributed unevenly around the Earth. Examine how resource management decisions are strongly related to water availability, quantity, and quality. The course examines water resources management; dams and dam removal; provision of safe potable water; threats to water quantity and quality; land use changes; the water economy; water laws and policy; institutions for water management at the global, national, regional, and local scale; and issues of water security and climate change.

Students will learn about magnification and how a magnifying lens works. They will examine a variety of different objects, first without a magnifier and then with a magnifier, and compare what they observe. They will practice observing details of these objects with magnifying lens. The purpose of this activity is for students to learn about observation skills and how tools can help people make observations, what "magnification" means, and to learn that scientists use tools, such as magnifying lenses, to examine objects. Students will be able to identify a magnifying glass and its purposes. They will be able to describe how the same object looks different when using the unaided eye versus a magnifying lens.
