Raising Student Awareness Of Environmental Issues Via Writing Assignments With Differential Equations, Michelle L. Ghrist

CODEE Journal

In this paper, I discuss two environmentally-focused writing assignments that I developed and implemented in recent integral calculus and differential equations courses. These models of carbon storage and PCB’s in a river provide interesting applications of one-compartment mixing problems. The assignments were intended to focus student attention on sustainability concerns while also developing other essential skills. I discuss these assignments and their effect on my students’ technical writing and environmental awareness. Detailed introductory instructions and mostly complete solutions to these assignments appear in the appendices, to include sample student work.

Solar Panels, Euler’S Method And Community-Based Projects: Connecting Differential Equations With Climate Change, Victor J. Donnay

CODEE Journal

How does mathematics connect with the search for solutions to the climate emergency? One simple connection, which can be explored in an introductory differential equations course, can be found by analyzing the energy generated by solar panels or wind turbines. The power generated by these devices is typically recorded at standard time intervals producing a data set which gives a discrete approximation to the power function $P(t)$. Using numerical techniques such as Euler’s method, one can determine the energy generated. Here we describe how we introduce the topic of solar power, apply Euler’s method to determine the energy generated, and …

Population Growth Models: Relationship Between Sustainable Fishing And Making A Profit, James Sandefur

CODEE Journal

In this paper, we develop differential equations that model the sustainable harvesting of species having different characteristics. Specifically, we assume the species satisfies one of two different types of density dependence. From these equations, we consider maximizing sustainable harvests. We then introduce a cost function for fishing and study how maximizing profit affects the harvesting strategy. We finally introduce the concept of open access which helps explain the collapse of many fish stocks.

The equations studied involve relatively simple rational and exponential functions. We analyze the differential equations using phase-line analysis as well as graphing approximate solutions using Euler's method, …

Importance Of Reinjection In Sustainability Of Geothermal Resources And Reinjection Well Locations In Türkiye, Nilgün Doğdu, Oktay Çelmen

Bulletin of the Mineral Research and Exploration

Sustainability of geothermal energy is related with the type of geothermal resources (natural springs, well), usage situations (thermal, residential-greenhouse heating, energy, etc.), amount of use (optimal flow, appropriate pressure-temperature changes), conservation of resources, and is mostly achieved by reinjection of the geothermal fluid returning from usage. It is important to take measures to prevent adverse changes in temperature and pressure conditions in the reservoir to properly remove the fluid returning from use in geothermal areas from the environment and recharge the reservoir. Reinjection should be carried out under appropriate conditions for the protection of resources. In the operation of geothermal …

Water: Arizona's Ticking Time Bomb, Bailey Wambold

Access*: Interdisciplinary Journal of Student Research and Scholarship

For a landlocked state dominated by desert, Arizona has done an exceptional job supporting tremendous development and population growth with limited water resources. However, as climate change and anthropogenic environmental degradation further stress the region’s already-strained water resources, the future of Arizona’s still-growing populace hangs in the balance as current water policies and practices are proving inherently unsustainable. Despite an abundance of literature citing the consequences of a liberal attitude towards water in an arid climate, a myopic focus on promoting Arizona’s economic and political growth has resulted in the state’s modern need to adopt previously-unseen conservation measures in order …

Back To The Future Or Forward To The Past: Ocean Voyaging And Slow Travel, Christina Gerhardt

Studies in 20th & 21st Century Literature

Going back to previous modes of travel, such as walking or sailing, to ensure a future, is currently being engaged by everyone from ambling environmentalists to scientists and technologists. In Germany and in Sweden, scientists are working to develop large cargo sailing ships. These ships of the future hearken back to the past of ocean voyaging. They dovetail with contemporary literary reflections on ocean voyaging and slow travels, such as Judith Schalansky’s Atlas of Remote Islands: Fifty Islands I Have Never Set Foot On and Never Will (2009). Weaving together an analysis of Schalansky’s atlas with environmental humanities discourses on …

Effects Of Stormwater Green Infrastructure On Watershed Outflow: Does Spatial Distribution Matter?, Benjamin Fahy, Heejun Chang

International Journal of Geospatial and Environmental Research

Green Stormwater Infrastructure (GSI) has become a popular method in urban stormwater management. We examined how spatial distribution of GSI affected rainfall-runoff relationships in a recently developed neighborhood in Gresham, Oregon, USA for the 2017-2018 water year. Runoff ratio, peak discharge, and flashiness were compared under four precipitation scenarios (of differing intensity and duration) and different spatial arrangements of GSI. Distributed GSI reduced runoff ratio (10 - 20%), peak discharge (26 - 68%), and flashiness index (56 - 70%). Distributed GSI outperformed centralized structures for all metrics, reducing runoff ratio (22 - 32%), peak discharge 67 to 69%, and flashiness …
