TITLE: Using updated hydrologic and hydraulic models to develop the Marengo River Watershed Management Plan
ABSTRACT: Degraded hydrology and erosion hazards have contributed to a number of flood disasters that have damaged local infrastructure such as roads, bridges, and culverts and impacted the livelihoods of communities within the Marengo River watershed in Northern Wisconsin. To better understand and mitigate the flood and erosion related risks in this watershed, we need better hydrologic and hydraulic (H&H) models. Updated H&H models would provide more in depth information about watershed functions and have a wide range of applications, such as delineating where wetlands and floodplains are disconnected from streams and assessing the vulnerability of critical infrastructure to being impacted by flooding. In this presentation, I will cover the process of updating H&H models for the Marengo River watershed using high resolution Lidar/elevation data, land cover, and culvert inventory data; and I will discuss how these H&H models will help inform the development of a watershed-wide management plan.
