## Abstract

Much of the Arctic is underlain by perennially frozen ground known as permafrost. Over the last few decades, the Arctic is thawing and destabilizing riverbanks and affecting infrastructure, water quality, and fish habitat. Additionally, a significant portion of the United States' natural resources and national security interests are contained within river corridors in Alaska. Arctic and Subarctic Federal, State, and Tribal governments need advanced knowledge and tools to identify and assess more accurately riverbank erosion vulnerability and risk in order to guide local decision-makers. Phase-1 of this work includes an interdisciplinary team of physical and social scientists, land managers, engineering design firms, stakeholders and land owners at local, tribal and federal levels. This team is well positioned to integrate advanced research techniques with community needs to document and forecast ongoing landscape and river changes, and enable the development of pragmatic solutions to protect investments in infrastructure. This project is poised to make an impact with science that informs public policy; increases partnerships between local community members, academia, industry, non-profit, and government sectors; and develops an American workforce in interdisciplinary applied science.

This project will develop new state-of-the-art approaches to critical and immediate environmental threats to communities and infrastructure in Arctic Alaska. Solution strategies include: 1) i
