Student teams practice water quality analysis through turbidity measurement and coliform bacteria counts. They use information about water treatment processes to design prototype small-scale water treatment systems and test the influent (incoming) and effluent (outgoing) water to assess how well their prototypes produce safe water to prevent water-borne illnesses.

" This course is a client-based land analysis and site planning project. The primary focus of the course changes from year to year. This year the focus is on Japan's New Towns. Students will review land inventory, analysis, and planning of sites and the infrastructure systems that serve them.ĺĘThey willĺĘalso examine spatial organization of uses, parcelization, design of roadways, grading, utility systems, stormwater runoff, parking, traffic and off-site impacts, as well as landscaping. LecturesĺĘwill coverĺĘanalytical techniques and examples of good site-planning practice. Requirements include a series of Assignments and Labs and a client-based project."

The course discusses several Geopgraphical Information System (GIS) and Remote Sensing (RS) tools relevant for analysis of (problems in and aspects of) water systems. Within the course, several applications are introduced. These applications include GIS tools to determine mapping of surface water systems (catchment delineation, reservoirs and canal systems). The RS tools include determination of evaporation and soil moisture patterns, and measurement of water levels in surface water systems. In exercises and lectures, different tools and applications are offered. For each application, assignments are given to allow students to acquire relevant skills. The course structure combines assignments and introductory lectures. Each week participants work on one assignment. These assignments are discussed in the next lecture and graded. Each week a new assignment is introduced, together with supporting materials (an article discussing the relevant application) and lectures (introducing theoretical issues). The study material of the course consists of a study guide, assignments, lecture material and articles. The final mark is the average of the grades of the individual assignments.

" A great variety of processes affect the surface of the Earth. Topics to be covered are production and movement of surficial materials; soils and soil erosion; precipitation; streams and lakes; groundwater flow; glaciers and their deposits. The course combines aspects of geology, climatology, hydrology, and soil science to present a coherent introduction to the surface of the Earth, with emphasis on both fundamental concepts and practical applications, as a basis for understanding and intelligent management of the Earth's physical and chemical environment."

Students are introduced to superhydrophobic surfaces and the "lotus effect." Water spilled on a superhydrophobic surface does not wet the surface, but simply rolls off. Additionally, as water moves across the superhydrophobic surface, it picks up and carries away any foreign material, such as dust or dirt. Students learn how plants create and use superhydrophobic surfaces in nature and how engineers have created human-made products that mimic the properties of these natural surfaces. They also learn about the tendency of all superhydrophobic surfaces to develop water droplets that do not roll off the surface but become "pinned" under certain conditions, such as water droplets formed from condensation. They see how the introduction of mechanical energy can "unpin" these water droplets and restore the desirable properties of the superhydrophobic surface.

Surface tension accounts for many of the interesting properties we associate with water. By learning about surface tension and adhesive forces, students learn why liquid jets of water break into droplets rather than staying in a continuous stream. Through hands-on activities, students learn how the combination of adhesive forces and cohesive forces cause capillary motion. They study different effects of capillary motion and use capillary motion to measure surface tension. Students explore the phenomena of wetting and hydrophobic and hydrophilic surfaces and see how water's behavior changes when a surface is treated with different coatings. A lotus leaf is a natural example of a superhydrophobic surface, with its water-repellent, self-cleaning characteristics. Students examine the lotus effect on natural leaves and human-made superhydrophobic surfaces, and explore how the lotus leaf repels dewy water through vibration. See the Unit Overview section for details on each lesson in this unit.

Students are introduced to the basic biology behind Pacific salmon migration and the many engineered Columbia River dam structures that aid in their passage through the river's hydroelectric dams. Students apply what they learn about the salmon life cycle as they think of devices and modifications that might be implemented at dams to aid in the natural cycle of fish migration, and as they make (hypothetical) Splash Engineering presentations about their proposed fish mitigation solutions for Birdseye River's dam in Thirsty County.

The Tippy Tap hand-washing station is an inexpensive and effective device used extensively in the developing world. One shortcoming of the homemade device is that it must be manually refilled with water and therefore is of limited use in high-traffic areas. In this activity, student teams design, prototype and test piping systems to transport water from a storage tank to an existing Tippy Tap hand-washing station, thereby creating a more efficient hand-washing station. Through this example service-learning engineering project, students learn basic fluid dynamic principles that are needed for creating efficient piping systems.
