Lake Mixing Module part of Project EDDIE:Teaching Materials:Modules
This module was initially developed by Carey, C.C., J.L. Klug, and R.L. Fuller. 1 August 2015. Project EDDIE: Dynamics of Lake Mixing. Project EDDIE Module 3, Version 1. cemast.illinoisstate.edu/data-for-students/modules/lake-mixing.shtml. Module development was supported by NSF DEB 1245707.
Stratified lakes exhibit vertical gradients in organisms, nutrients, and oxygen, which have important implications for ecosystem structure and functioning. Mixing disrupts these gradients by redistributing these ...

Unit 1: Climate Change and Sea Level: Who Are the Stakeholders? part of Understanding Our Changing Climate
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
How are rising sea levels already influencing different regions? This unit offers case study examples for a coastal developing country (Bangladesh), a major coastal urban area (southern California), and an island ...

Nutrient Loading Module part of Project EDDIE:Teaching Materials:Modules
This module was initially developed by Castendyk, D.N., T. Meixner, and C.A. Gibson. 6 June 2015. Project EDDIE: Nutrient Loading. Project EDDIE Module 7, Version 1. Module development was supported by NSF DEB 1245707.
Estimating nutrient loads is a critical concept for students studying water quality in a variety of environmental settings. Many STEM/Environmental science students will be asked to assess the impacts of a proposed anthropogenic activities on human water resources and/or ecosystems as part of their future careers. This module engages students in exploring factors contributing to the actual loads of nitrogen that are transmitted down streams. Nitrogen is a key water quality contaminant contributing to surface water quality issues in fresh, salt, and estuarine environments. Students will utilize real-time nitrate data from the US Geological Survey to calculate nitrate loads for several locations and investigate the interplay of concentration and discharge that contributes to calculated loads.

11. Composting Toilets part of Renewable Energy and Environmental Sustainability
Maurice Crawford, University of Maryland-Eastern Shore; Benjamin Cuker, Hampton University
Toilet use accounts for the largest use of water in single family homes. In 2016, the average US household toilet accounted for a quarter of a home's total indoor water. Compost toilets are one method that may ...

Unit 3: Monitoring groundwater storage with GPS vertical position part of Measuring Water Resources
Bruce Douglas, Indiana University-Bloomington; Eric Small, University of Colorado at Boulder
This unit shows how GPS records of surface elevation can be used to monitor groundwater changes. Students calculate secular trends in the GPS time series and then use the original and detrended records to identify ...

Unit 4: Water budget assessment of a California drought part of Measuring Water Resources
Bruce Douglas, Indiana University-Bloomington; Eric Small, University of Colorado at Boulder
The California Drought of 2012–2016 had significant social and economic consequences. This final unit focuses on this drought as a case study for measuring the hydrologic system so that we can better understand ...

Unit 1: Introduction to the hydrologic cycle and stakeholder analysis part of Measuring Water Resources
Bruce Douglas, Indiana University-Bloomington; Eric Small, University of Colorado at Boulder
This unit introduces the hydrological cycle to provide context for the module as a whole. It particularly focuses on those portions of the hydrological cycle that take place on land and that form the basis for ...

Unit 2: Characterizing groundwater storage with well and GRACE data part of Measuring Water Resources
Bruce Douglas, Indiana University-Bloomington; Eric Small, University of Colorado at Boulder
This unit provides students with experience analyzing traditional (depth to water table measured in a well) and geodetic: GRACE (Gravity Recovery and Climate Experiment) data for monitoring changes in groundwater ...

Unit 6.2 - Biogeochemical Examples part of Critical Zone Science
Adam Hoffman, University of Dubuque
In this week-long unit students will explore Critical Zone function and dynamics as they relate to nutrient cycling in agricultural systems and nutrient pollution into aquatic systems. This unit is generally ...

Unit 5.2 - Water Balance Impacts part of Critical Zone Science
Martha Conklin, University of California-Merced
This is the second module of a two week-long unit on hydrology in an upper-level undergraduate course on the Critical Zone. After Unit 5.1, students should have a basic understanding of the fluxes and reservoirs in ...
