Title: Characterizing Lowland Streams: Riparian and Watershed Influences on Urban and Non-Urban Channels
Author: Segura Sossa, Catalina
Abstract: This thesis presents a suite of studies focused on the channel network of the Chico Creek watershed, a resource-rich stream system on the Kitsap Peninsula in western Washington State. This analysis included characterization of the stream network into channel types and a rapid assessment of the current geomorphic condition of these streams. In addition, the relationship between urbanization metrics (based on land cover) and the current physical condition of the stream channels was explored. This analysis allowed the identification the relatively pristine sites and also identified potential monitoring and restoration areas. This characterization is a contribution to the physical understanding of the basin's stream channels in the context of the recent completed study, "The Chico Creek watershed planning project." The overall objective of this project was to develop a science-based vision of the Chico Creek watershed for the future under different trajectories of future urban development. Recognizing the dominant geomorphologic processes in fluvial channels provides guidance for defining current channel condition and identifying possible monitoring sites to show response to upstream impacts. In addition, this understanding can illuminate areas where restoration efforts are appropriate and can contribute to creating or defining target morphologic features.
