This is the web syllabus for Environmental Hydrogeology (Geology 210). In addition to your weekly readings and assignments, I will also post web resources here each week and provide links to keys for quizzes and exams. Please let me know if you discover a site that may be appropriate to that week's topic. Refer to class notes at the bottom of this page for your responsibilities, schedule of fieldtrips and course evaluation.
The purpose of this course is to provide the fundamentals central to the study of water as a resource. I assume a general knowlege of basic geology: sediments, rocks, stratigraphy, and structural geology. The first part of the class is dedicated to the hydrologic cycle, surface water processes and the geology of groundwater. Part two focuses on understanding the fundamentals of groundwater flow and flow to wells. Part three is concerned with water chemistry and contamination issues. Finally we will briefly examine how groundwater can be used in to tell us about past environmental conditions and how the geologic record can help us to manage groundwater as a resource.
One of the primary goals is to develop an understanding of the principles that are necessary to describe, model and work toward better management of groundwater as a resource. Central to the exercises in the field and laboratory is an emphasis on the critical thinking needed to evaluate and interpret real world hydrogeologic data. In order to acheive these goal we will be conducting field exercises as listed below. Our lectures and labs will be combined. Some lectures will meet in in Taylor 210. The field excursions will leave from the traffic circle north of Scovel Hall.

Introduction to the Climate System and the Hydrologic Cycle |
| Reading: F: 1-25; Dingman (handout) (preparation questions) | |
| Lab: Spreadsheet model of the hydrologic cycle | |
| Assignments: 30 August meets in Taylor 210 | |
|
Web Resources for Week #1: Dingman outlines the global hydrologic cycle beginning with a discussion of the Earth's energy (NRG) balance. The spatial receipt of solar NRG to the planet across the latitudes and its redistribution drives atmospheric circulation, which in part, determines the global distribution of precipitation. Precipitation then drives the hydrologic cycle. The EPA site concerned with the hydrologic cycle and humankind's impact is a good place to start. To see how Ohio's water is used visit the Ohio State University Extension Fact Sheet on Ohio's hydrologic cycle. Colorado State University presents a more global view of the allocation of water at its site. You should also know about the Applied Hydrogeology text web page. Here you will find corrections to the text if some of what you read and in particular some of the math does not seem right - it may be the book and not you. Also available at this site are solutions to problems in the back of each chapter, which may be good as practice exercises or I may even assign a few of these. |

Surface and Groundwater Interaction |
| Reading: F: 27-76. (preparation questions) There will be a bridf quiz on Friday. | |
| Lab: Stream gaging and Stream Permeability Measurements on the Killbuck - Northwellfield, Wooster 2 September and 5 Sept. | |
| Assignments: Hand in the significant figure exercise on Monday (2 September). Field labs at the North Wellfield will be on Monday and Thursday - if you can come Thursday. Vans leave from North Scovel Circle at 1 pm sharp. Fill out a release of liability form. | |
|
Web Resources for Week #2: This week we will be using data from the US Geological Survey gaging stations and performing field work in the Killbuck drainage basin. Check out the EPA surf your watershed site to get an idea of the local watershed in our area. Texas is the answer to the bonus question on which state is currently experiencing a major drought, to learn more about drought in the US from a paleoerspective visit the NOAA drought page. Part of the hydrologic spreadsheet involves the inevitable unit conversions cruise the web for pages (Web caution, test that the conversions are correct) that easily to the conversions for you, this is one that I use is found here. Announcements: Tuesday at 11 AM is a meeting of the GEOCLUB, we will take the Geology picture at that time. Jessica Conroy and Katherine Nicholson are the speakers for Thursday's GEOCLUB, you all should attend. |

We will be hearing about the research of Ed McCoy and then head down the road to Holmes County to examine aquifer materials and talk about the history of the Wooster buired valley aquifer. Start your investigation of the hydrology of putting greens here. | |
| Web Resources for Week #3: For a fieldtrip guide and good summary of contaminant issues of the Wooster Aquifer see a site based on E. Scott Bair's fieldtrip guide. Other sites that described the Wooster Aquifer include reports that we will become familiar with from the USGS and fact sheets from The Ohio Ste University's Extension. For general discussions take a look at the pages put out by the Groundwater Foundation for a good review and primer for out discussons this week. | |

| Web Resources for Week #4: Read about Henri Darcy and his law here. The Know Your Watershed campaign, coordinated by the Conservation Technology Information Center (CTIC) gives an excellent review of groundwater/ surface water interactions and lots more. I have not found a good site that will help us with unit conversions in this class. In your spare time you may want to expand your spreadsheet exercise and set up a web page to take care of this shortcoming on the Web. | |

All fieldtrips are required for the class and vans will leave at 1 pm from the front of Scovel Hall. For each of the trips, each student is required to fill out a waiver form. Labs are due as noted on the lab handouts, no late work will be accepted. Three exams including a comprehensive final will (9:00 am Monday 9 December) make up 45% of your total grade, quizzes 15% and field and lab reports 25%. In addition to thse evaluations your general participation in the final project and class, field and lab will count toward 15% of the final grade. Most quizzes will be announced, however I will occasionally give a pop quiz in lecture or lab, the two lowest scores of the ten quizzes will be dropped. Each student is required to analyze a hydrogeologic data set for a written 8-10 page paper (with figures). You will need to meet with the instructor to identify interests and availability of data for your project. A project timetable will be handed out in class. Each week I will post my office hours on my office door (Scovel 119). In addition, feel free to contact me by e-mail (gwiles@acs.wooster.edu) or by phone (X-2298).
