Students Learn About Glacial Flooding Threatening Their School

The threat of glacial outburst floods looms large over communities nestled near rapidly receding glaciers, a stark reminder of the profound impact of climate change on our environment.

In Alaska's vibrant Mendenhall Valley, residents are grappling with the recurring devastation caused by these powerful surges of water. Thunder Mountain Middle School, situated precariously beside the Mendenhall River, has found itself in the crosshairs of this natural phenomenon twice within the past two years.

Understanding the Science Behind Glacial Outburst Floods

Eighth-grader Vivian Esmiol, a student at Thunder Mountain Middle School, has gained firsthand insight into the complex science behind these floods. She explains that the root cause lies in the Suicide Basin, an area situated between the Mendenhall Glacier where meltwater accumulates during spring and summer. This buildup of pressure against the ice eventually leads to a sudden and catastrophic release of water, resulting in devastating glacial outburst floods.

Esmiol's Earth Science class, led by Jess Stanley, delved deep into the intricate workings of these floods, empowering students with knowledge about the impact of climate change on their local environment. The curriculum encompassed mapping the river, analyzing rainfall and snowpack patterns, and exploring the far-reaching consequences of glacial melt on downstream communities.

Climate Impact: A Growing Concern

The connection between these glacial outburst floods and the broader issue of climate change is undeniable. As global temperatures rise, glaciers melt at an accelerated rate, contributing to the increased frequency and severity of these flooding events. The melting ice not only raises sea levels but also disrupts delicate ecosystems and poses a significant threat to human settlements.

Flood Protection: Building Resilience

In response to the recurring floods, local authorities have implemented measures to enhance flood protection in the Mendenhall Valley. Construction crews are extending the levee further downstream to safeguard Thunder Mountain Middle School, businesses, and residential areas from potential inundation. The project includes the installation of HESCO barriers, which act as a physical barrier against floodwaters.

Students have actively participated in learning about these flood protection efforts, sketching HESCO barriers and engaging in discussions about the challenges and complexities of mitigating the risks associated with glacial outburst floods.

Empowering the Next Generation

The students at Thunder Mountain Middle School are not simply passive recipients of knowledge; they are actively engaged in raising awareness about the importance of climate change mitigation and flood protection. They are creating posters with QR codes that link to valuable information about flood preparedness, planning to distribute them throughout the community this summer.

Through their efforts, these young minds are inspiring others to take action, promoting a sense of collective responsibility for protecting their environment and ensuring a more resilient future in the face of climate-induced challenges.

The lessons learned at Thunder Mountain Middle School serve as a powerful reminder that education plays a pivotal role in shaping informed citizens who are equipped to address the pressing issues of our time. By fostering a deep understanding of the interconnectedness between climate change, glacial outburst floods, and flood protection, we can empower future generations to become stewards of a sustainable planet.
