Abstract
Extensive research has studied the near-field tsunami threat in the Cascadia Subduction Zone (CSZ), but little research has examined the ability to evacuate the inundation zone before the first tsunami wave arrives. To address this gap, this study provides empirical evidence about people's expectations about hazard onset and evacuation logistics when a tsunami threatens. We surveyed households in five CSZ communities to assess residents' expected first wave arrival time, as well as their expectations about evacuation destinations, route choices, preparation times, travel times, and clearance times. Heatmaps are used to summarize residents' evacuation destinations and route choices, and probabilistic functions are used to model evacuation distances and time estimates. The results suggest that respondents have similar patterns of time estimates, but a few plan to evacuate within the inundation zone, and some plan to evacuate on routes that were congested in a previous event and end their evacuations at destinations within the inundation zone.

Abstract
Urban waterfronts are rarely designed to support biodiversity and other ecosystem services, yet have the potential to provide these services. New approaches that integrate ecological research into the design of docks and seawalls provide opportunities to mitigate the environmental impacts of urbanization and recover ecosystem function in urban waterfronts. A review of current examples of ecological design in temperate cities informs suggestions for future action. Conventional infrastructures have significant and diverse impacts on aquatic ecosystems. The impacts of conventional infrastructure are reduced where ecological designs have been implemented, particularly by projects adding microhabitat, creating more shallow water habitat, and reconstructing missing or altered rocky benthic habitats. Opportunities for future research include expanding current research into additional ecosystems, examining ecological processes and emergent properties to better address ecosystem function in ecological design, and addressing the impact of and best practices for continuing maintenance. Planned ecological infrastructure to replace aging and obsolete structures will benefit from design feedback derived from carefully executed in situ pilot studies.

Abstract
Data of open water evaporation (E-ow), such as evaporation of lake and reservoir, have been widely used in hydraulic and hydrological engineering projects, and water resources planning and management in agriculture, forestry and ecology. Because of the low-cost and maneuverability, measuring the evaporation of a pan has been widely regarded as a reliable approach to estimate E-ow through multiplying an appropriate pan coefficient (K-p). K-p is affected by geometry and materials of a pan, and complex surrounding environment variables. However, the relationship between K-p and different environment variables is unknown. Thus, this study chose China D20 pan as an example, used meteorological observations from 767 stations and introduced the latest PenPan model to analyze the sensitivity of K-p to different environment variables. The results show that, the distribution of annual K-p had a strong spatial gradient. For all the stations, annual K-p ranged from 0.31 to 0.89, and decreased gradually from southeast to northwest. The sensitivity analysis shows that for China as a whole, K-p was most sensitive to relative humidity, followed by air temperature, wind speed and sunshine duration. For 767 stations in China, K-p was most sensitive to relative humidity for almost all the stations. For stations north of Yellow River, wind speed and sunshine duration were the next sensitive variables; while for stations south of Yellow River, air temperature was the next sensitive variable. The method introduced in this study could benefit estimating and predicting K-p under future changing environment.

Ken Yocom is the Interim Dean of the College of Built Environments and a Professor in the Department of Landscape Architecture. He also has an adjunct appointment in the Department of Urban Design and Planning, serves on the steering committee of the PhD in the Built Environments Program, and is core faculty for the Interdisciplinary PhD Program in Urban Design and Planning within the College of Built Environments. He primarily teaches seminar and studio courses in theory, ecology, and urban design.
Trained as an ecologist and landscape architect with professional experience in the environmental consulting and construction industries, he is a graduate of our MLA program (2002). Ken also earned his PhD from the Program in the Built Environments (2007), where he researched nature and society relations through the contemporary context of urban ecological restoration practices.
Ken’s current research, teaching, and practice explore the convergence of urban infrastructure and ecological systems through adaptive design approaches that serve to demystify emerging strategies and technologies for sustainable and resilient development. More specifically, he investigates how water –in all its forms- shapes the past to future functions and patterns of our built environments. He has written extensively on the themes developed from his work including two books, Ecological Design (with Nancy Rottle, Bloomsbury, 2012) and NOW Urbanism: The Future City is Here (with Jeff Hou, Ben Spencer, and Thaisa Way (editors), Routledge, 2014). He has also written for professional practice and scholarly publications on issues of global biodiversity, urban environmental governance, ecological design, and contemporary nature and society relations in the urban context.
In his teaching, Ken emphasizes the development of a holistic and integrated approach that embraces the complexity of our built environments, yet discreetly explores the intersections and overlaps that frame our understanding and appreciation of particular places. He has a strong belief that collaboratively, the allied design professions can act as catalysts in recognizing, utilizing, and transforming the inherent potential of our built environments into places that are socially equitable, environmentally just, and economically sustainable.
