Unit 2: Monitoring surface and groundwater supply in central and western US part of Eyes on the Hydrosphere: Tracking Water Resources
Jonathan Harvey (Fort Lewis College) and Becca Walker (Mt San Antonio College)
In Unit 2, students learn how the techniques for water budgeting (covered in Unit 1) can be used to monitor both groundwater (High Plains Aquifer) and surface water (western mountain watershed) systems. Students ...

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 ...

Nutrient Monitoring in the Chesapeake Bay part of Project EDDIE:Teaching Materials:Modules
Akinyele Oni, Morgan State University; Niangoran Koissi, Morgan State University
The Chesapeake Bay waters receive input from rivers and streams from areas of Washington D.C, Maryland, Delaware, Virginia, West Virginia, and some parts of New York and Pennsylvania. Historically, humongous ...

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.

Module 4: Food and Water part of Future of Food
Gigi Richard, Fort Lewis College
In this module, students will be introduced to the connections between water and agriculture. The first part of the module (4.1) explores how water is essential for growing food and how water is embedded in all of ...

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 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 2.1: Hydrologic Impact of Land-Use Change part of An Ecosystem Services Approach to Water Resources
John Ritter, Wittenberg University; Meghann Jarchow, University of South Dakota; Ed Barbanell, University of Utah
In this activity, students model the impact of land-cover changes on stormwater runoff using the EPA's National Stormwater Calculator (Calculator). The students are introduced to the Calculator through a ...

Stream Discharge Module part of Project EDDIE:Teaching Materials:Modules
This module was initially developed by Bader, N.E., T. Meixner, C.A. Gibson, C.M. O'Reilly, and D.N. Castendyk. 26 June 2015. Project EDDIE: Stream Discharge. Project EDDIE Module 5, Version 2. cemast.illinoisstate.edu/data-for-students/modules/stream-discharge.shtml Module development was supported by NSF DEB 1245707.
Stream discharge is a fundamental measure of water supply in stream systems. Low discharge may cause problems with water supply and fish passage, while high discharge may mean flooding. In this module, students ...

Major Ions in Freshwater Systems part of Project EDDIE:Teaching Materials:Modules
Megan Kelly, Loyola University Chicago
Dissolved ions are present in all freshwater systems, but humans can change the chemical composition of freshwater in several ways. In this activity, students will examine the concentration of major ions in ...
