🏡 CASE STUDY | Earlier this year we released our first monitoring report on progress against the New Zealand Infrastructure Strategy. The report found that more action is required when it comes to strengthening resilience to shocks and stresses. But there’s some positive work being done. For example, new stormwater solutions that Kāinga Ora - Homes and Communities incorporated in new developments in Northcote, Mt Roskill, and Ōwairaka functioned as planned during the Auckland Anniversary floods in January 2023. The result? Huge amounts of water were diverted away from homes that would otherwise have been flooded and badly damaged. The Northcote Development, Greenslade Reserve operates not only as a sports ground and park for the community, but also a stormwater detention basin. During the January 2023 floods the reserve filled up and contained most of the floodwaters. Once the rains stopped, the surface water drained away and the community could once again enjoy using the grassy reserve.

It’s now proven that native trees can provide better bank stabilisation, reducing landslide risks and controlling erosion. 🌳🙌 So rather than jumping straight to hard revetment, it might be worth reviewing native regeneration as the first priority. 🍃 This article is timely given the recent heavy rainfall in FNQ, for more details click below. 💧

Just Published! Excited to share our latest research on flood resilience in coastal slums of the Global South! Check out our chapter "Lessons from Coastal Slums of Global South Toward Flood Resilience" in the book Greening Our Cities: Sustainable Urbanism for a Greener Future. This work explores innovative strategies and community practices that enhance flood resilience in some of the world's most vulnerable urban areas. We believe these insights can contribute significantly to global discussions on sustainable urban development and climate adaptation. 📖 Read the full chapter here: https://lnkd.in/dMRQ5Pwf Thanks to my co-author Prof. Maria Matos Silva and Prof. Sérgio Proença, the editors for making this publication possible! #Research #FloodResilience #GlobalSouth #SustainableUrbanism #UrbanDevelopment #ClimateAdaptation #Springer University of Lisbon UrbinLab Faculdade de Arquitetura - Universidade de Lisboa Citation: Goyal, A., Silva, M.M.

Based on the Murray-Darling Basin Authority (MDBA website), river banks are "the space between the banks of the river basin and the inner embankment legs located on the left and/or right of the river bank". The boundary of the riverbank is the virtual line on the left and right of the riverbed which is defined as a river protection boundary. "Riverbanks in urban areas, such as Zayanderoud River in Isfahan City, are not only affected the quality of river water, but also affected by the community's behavior on their environment. Improving the quality of riparian and riverbed landscapes can support scale-change changes. In addition, the riverbank facilitates lateral and vertical connectivity along the river. People in developing countries make the river as a place to do various activities such as fishing, washing clothes, supplying raw water, recreation, or farming. The riverside farm provides local crop production for the surrounding settlements. Such riparian and river utilization activities are very useful and serve to maintain and improve its quality. The retaining wall, therefore, not only prevents erosion but also facilitates the sustainable use of the river's resources, fostering a harmonious relationship between the community and their natural surroundings. This training wall is modeled in #CIVIL3D environment. #RetainingWall #RiverEnginnering #SustainableLandscapes #RiparianEcosystem #ZayanderoudRiver #WaterQuality #ErosionControl

Kongjian Yu (DDes '95) has developed the concept of "sponge cities," which he calls "tai chi with water": slowing floodwaters and redirecting them so they have room to spread out. Read more (including a quote from GSD's Niall Kirkwood) at the NYT! https://lnkd.in/dwA89ad4

“New Zealand’s braided rivers: The land the law forgot”   New Zealand is the home to an excess of 150 gravel-bed braided rivers.    As recently noted by Brower et al. (2023), these powerful morphodynamic systems are prone to recurrent bar reworking and channel shift.  When parts of the riverbed are temporarily abandoned by active channels, they are vulnerable to land use intensification.   Associated flood protection measures that often follow intensification constrict the rivers' capacity to adjust to ever-changing flows of water and sediment.  Despite the rivers' vulnerability and constriction, New Zealand law defines braided rivers in a way that limits local councils' authority to manage land use within the braid plain.  One such example is New Zealand's Rangitata River.   See Brower et al. (2023) in Earth Surface Processes and Landforms, “New Zealand’s braided rivers: The land the law forgot”

I'm pleased to report that the Loch Lomond & The Trossachs National Park Planning & Access Committee has unanimously approved a planning application for 18 new houses in the village of St Fillans. Bidwells submitted the application over 2.5 years ago and despite it being the only LDP allocated housing site in the village, extensive supporting information was required resulting in a protracted determination process. This included a flood risk assessment, drainage design, ecological survey, tree survey and arboricultural report, detailed landscaping proposals, transport assessment, planning, design and access statement, and a viability appraisal that addressed the delivery of affordable housing. Evidence of an example where the planning process has to be improved to help with the well-documented housing crisis that's seriously affecting this country. #housingcrisis #planningprocess
