Urban Riverscapes: Reconnecting Urban Environments With the River Landscape

<p>Water is a fundamental component of New Zealand’s landscape, culture, history and identity. It is moving, changing form, accumulating and dispersing, it is ever changing never in the same context twice. Rivers are a single representation of this process in which we experience water in the landscape.  New Zealand has beautiful and intense water ways that pass through urban environments, yet due to the flood protection measures in place, they are disconnected from the urban environment. They are difficult to access and do not hold a presence in our growing urban environment which they once had significance in.  Stopbanks are the most common form of river flood protection infrastructure in New Zealand. They treat the river as a static element without giving them the space to move, flood and meander. They create a physical barrier between the urban environment and river space and do not respond to the differences of rivers and urban environments.  Growing urbanisation is increasing the pressure on stormwater infrastructure and growing the risk and effects of flooding. Increasing magnitude and frequency of rainfall events is only putting more pressure on flood protection infrastructure and stopbank infrastructure is crumbling under the pressure. Urban environments are requiring a larger level of flood protection that the traditional stopbank can provide.  This thesis is an investigation into the role of stopbanks for flood protection in urban river spaces and their effect of the experiential and ecological experience of the river. This investigation, developed through an analysis of the Waiwhakaiho River in New Plymouth, the Waikanae River in Kapiti and the Waipoua River in the Waiarapa informs a redesign of flood protection measures in New Zealand medium sized towns to repair the disconnection of the urban environment to the river.</p>
