This course, is designed to be a descriptive and analytical overview of water organs, availability, location and flow. It will be examined in the light of problems, possibilities and policy and consider historical perspectives.

At the University of Vermont, instructors used land use change, driven by development of the University of Vermont campus and recent student occupancy of surrounding neighborhoods in Burlington, Vermont, as an opportunity for service learning and for teaching fundamental hydrologic and geologic skills. Students from a Geomorphology class, Geohydrology class and student senior research projects all worked on the preoject. In each of these studies, students worked closely with City and University staff and presented results at local forums, professional national meeting, and on the World Wide Web. These service-learning projects have received positive feedback from the students, city officals, and community members.

The course deals with the principles of hydrology of catchment areas, rivers and deltas. The students will learn:

1). to understand the relations between hydrological processes in catchment areas
2?. to understand and to calculate the propagation of flood waves
3). to understand hydrological processes in deltas
4). to draft frequency analysis of extremes under different climatological conditions.

This sample of plausible questions and responses is designed to help guide the instructor through an entire Socratic lesson. Specifically, it will help instructors learn how to create Socratic questions and design a session of Socratic questioning. It begins with a general question about the hydrosphere, then explores components of the hydrosphere, and finally moves to the specific case of a change in surface material/land cover at Earth's surface.

This Summary for teachers is inspired by the IPCC's Special Report on the Ocean and Cryosphere in a Changing Climate. This resource is a teacher-friendly version of the Summary for Policymakers of the IPCC report. Useful infographics and ideas for short class activities are provided, as well a glossary and a list of educational resources.

Students explore for water on Mars using impact crater morphology. During this lab, students: learn to use the equation writing and graphing capabilities in Microsoft Excel, thendevelop and apply an impact crater depth-diameter relationship in an effort to constrain the depth to a possible water-rich layer beneath one or more portions of the surface of Mars!

The suburban city of Mount Rainier, Maryland, is doing its part to improve the water quality of a polluted river in its region: residents and organizations are using green infrastructure to reduce stormwater runoff.

A toddler wading pool or similar tank is filled with common sand (available from home improvement stores in bags) to a depth of 15-20 cm. The sand is saturated with a slow inflow and outflow to a floor drain. A 2-inch PVC slotted screen section is buried in the sand near the center of the tank with a capped end at the bottom. Small (1 cm diameter or similar) slotted or perforated PVC or copper tubing are placed as piezometers in the sand at short distances (e.g., 10-20 cm) from the pumping "well." A fountain pump capable of discharging up to 100-150 ml/min is placed within the "well" with adequate discharge tubing to conduct the water to a drain. A stopcock is placed in the tubing to control flow. Alternatively, if the tank of sand is on a very sturdy table, a simple siphon with tubing can be used as a pump. Drawdown is determined by the difference between a pre-pumping level measurement from the top of the "piezometers" and subsequent measurements made in the same "piezometer" at times after pumping starts. Water levels may be measured using chalked wooden rods. Alternatively, a small cork with a slender wooded food skewer marked in millimeter increments can be placed in each piezometers and the students can watch the change in level of the markings relative to the top of the "piezometer." Flow is repeatedly measured using a graduated cylinder. At the start of the test, students or teams of students are assigned to either take water level measurements at a specific piezometer or to measure and control the flow rate. The data are collected on a logarithmically increasing time interval for about an hour. The flow and drawdown data are analyzed by various means (Theis curve, Jacob straight-line method, Bolton curves, etc.) either manually or using AQTESOLV or similar software. Though the drawdowns are small, the data have provided quite reasonable estimates of hydraulic conductivity for the sand.

It is still unknown whether the cluster of childhood leukemia cases in east Woburn was caused by TCE and PCE contamination from five known sources of contamination within the capture zones of municipal wells G and H, or whether the leukemias were caused by induced infiltration of Aberjona River water, which may have contained dissolved concentrations of arsenic, chromium, and lead. Several papers have been written about the arsenic, chromium, and lead contamination in Woburn. These papers could be read, combined with a broad discussion about mobility of heavy metals under different oxidation states, hypotheses drawn by the class, and experiments designed by the students to ascertain whether contaminated river water could have reached wells G and H. Designing an experiment to test an hypothesis is a higher-order thinking skill needed by all scientists and engineers.

This project is a way to assemble information about geology, hydrogeology, and soils into a coherent whole in a way that may otherwise not happen in any one class. The "critical zone" concept ties the pieces together. This project is not tied to a course but I have used it as a component of a senior assessment for geology students.

The lectures introduce a number of topics that are important for IWRM and the modeling exercise. The lectures introduce water management issues in the Netherlands, Rhine Basin, and Volta Basin. The role-play is meant to experience some of the social processes that, together with technical knowledge, determine water management.

The City of Ann Arbor recognized stormwater runoff as a growing threat to the quality of their water supply. They're addressing the issue with two complementary strategies.

In this lab, students investigate groundwater flow and water quality within a groundwater well field on the CSU campus. The well field is part of the GroundWater Education and Teaching (GetWET) Observatory south of the Hilton Inn off Centre Drive. Students determine water flow paths and rates as well as measure water quality parameters such as water temperature, pH, electrical conductivity, and dissolved oxygen.

Materials needed for this lab include:

Groundwater equipment: Groundwater well or wells adjacent to a perennial stream.
Water quantity equipment: Electronic water meter, staff, plate, tape, stop watch, and float to measure surface velocity.
Water quality equipment: pH, temperature specific conductance, and dissolved oxygen meters, bailer, and bucket to collect samples.
Other equipment: Map of site showing location of wells and stream.

Students are presented with examples of the types of problems that environmental engineers solve, specifically focusing on water quality issues. Topics include the importance of clean water, the scarcity of fresh water, tap water contamination sources, and ways environmental engineers treat contaminated water.
