Rivers are the lifeblood of many cities, but flood risk is projected to increase due urbanisation and climate change. Better floodplain management in near urban areas required produce New Urban Agenda’s ‘just, safe, healthy, accessible, affordable, resilient sustainable cities’. Many jurisdictions looking move or keep people out human-constructed residential ‘niches’ on hazardous floodplains, this has proved difficult achieve. Our historical case studies colonial societies ancient Rome, as well Yangtze, Mississippi Brisbane rivers, show deep roots contemporary issues, such failures perception related recent settlement, moral hazard spending defence infrastructure, creeping nature encroachment into perceived protection created by structural interventions, need for a central, ‘whole river’ approach, difficulties implementing approach locally. These also suggest solutions, including adoption Indigenous perspectives, benefits incentivise local actors education strategy appetite more mitigation.

Abstract Stormwater biofilters are one of the most widely used nature-based solutions for urban water management. In last 20 years, have been extensively studied their pollutant removal performance; however, application in field is limited by high maintenance requirements. this work, we propose concept zero additional (ZAM) as a solution to challenge. To understand design and operation ZAM biofilters, three-stage research programme was conducted (i) examine filter media configurations that could protect against surface clogging, (ii) test performance variety lawn grasses, (iii) validate laboratory findings through monitoring. The results showed protective layer delayed onset clogging. Five grasses – Kenda Kikuyu, Empire Zoysia, Santa Ana Couch, Village Green Kikuyu Palmetto Soft Leaf Buffalo were found effectively reduce nitrogen concentrations meet other local pollution reduction Monitoring three field-scale confirmed nutrient heavy metal performance. Overall, these studies confirm potential well-designed achieve stormwater management requirements with no compared standard street landscaping.
