Podolak Multifunctional Riverscapes
Multifunctional Riverscapes: Stream restoration, Capability Brown’s water features, and artificial whitewater By Kristen Nicole Podolak A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Landscape Architecture and Environmental Planning in the Graduate Division of the University of California, Berkeley Committee in charge: Professor G. Mathias Kondolf, Chair Professor Louise Mozingo Professor Vincent H. Resh Spring 2012 i Abstract Multifunctional Riverscapes by Kristen Nicole Podolak Doctor of Philosophy in Landscape Architecture and Environmental Planning University of California, Berkeley Professor G. Mathias Kondolf, Chair Society is investing in river restoration and urban river revitalization as a solution for sustainable development. Many of these river projects adopt a multifunctional planning and design approach that strives to meld ecological, aesthetic, and recreational functions. However our understanding of how to accomplish multifunctionality and how the different functions work together is incomplete. Numerous ecologically justified river restoration projects may actually be driven by aesthetic and recreational preferences that are largely unexamined. At the same time river projects originally designed for aesthetics or recreation are now attempting to integrate habitat and environmental considerations to make the rivers more sustainable. Through in-depth study of a variety of constructed river landscapes - including dense historical river bend designs, artificial whitewater, and urban stream restoration this dissertation analyzes how aesthetic, ecological, and recreational functions intersect and potentially conflict. To explore how aesthetic and biophysical processes work together in riverscapes, I explored the relationship between one ideal of beauty, an s-curve illustrated by William Hogarth in the 18th century and two sets of river designs: 18th century river designs in England and late 20th century river restoration designs in North America.
