In the Valencia 2024 flood alone, the Spanish Insurance Compensation Consortium reported about 144,000 vehicles damaged or destroyed, many of them mobilized by the flow, which demonstrates the scale of large\u2010debris impacts during floods. Debris alters and intensifies flooding impacts by clogging drainage systems and streets, decreasing flow conveyance, and causing direct damage to infrastructure, lives, and ecosystems. Nevertheless, debris dynamics are largely absent from flood risk assessments and management strategies. This Commentary highlights the urgent need to integrate debris considerations into urban flood planning and emergency response. Using case studies from recent catastrophic floods, we illustrate how debris amplifies hazard. We explore emerging scientific insights into the influence of debris in different flood types (flash, fluvial, coastal, tsunamis), and discuss why current management strategies fail to incorporate this factor. A solution\u2010oriented roadmap is possible and we propose an actionable strategy toward the integration of debris into flood risk management, contributing to adapting cities toward higher levels of safety and resilience.<\/jats:p>","DOI":"10.1029\/2025wr041574","type":"journal-article","created":{"date-parts":[[2025,12,20]],"date-time":"2025-12-20T03:50:12Z","timestamp":1766202612000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Why Should Urban Debris Dynamics Be Considered in Urban Flood Management?"],"prefix":"10.1029","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0265-8581","authenticated-orcid":false,"given":"M\u00e1rio J.","family":"Franca","sequence":"first","affiliation":[{"name":"Institute for Water and Environment Karlsruhe Institute of Technology  Karlsruhe Germany"}]},{"given":"Rose","family":"Cook","sequence":"additional","affiliation":[{"name":"School of Engineering University of Birmingham  Birmingham UK"}]},{"given":"Ali","family":"Pourzangbar","sequence":"additional","affiliation":[{"name":"Institute for Water and Environment Karlsruhe Institute of Technology  Karlsruhe Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5784-9211","authenticated-orcid":false,"given":"Xilin","family":"Xia","sequence":"additional","affiliation":[{"name":"School of Engineering University of Birmingham  Birmingham UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7127-7547","authenticated-orcid":false,"given":"Daniel","family":"Valero","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering Imperial College London  London UK"}]},{"given":"Davide","family":"Vanzo","sequence":"additional","affiliation":[{"name":"Institute for Water and Environment Karlsruhe Institute of Technology  Karlsruhe Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5007-0208","authenticated-orcid":false,"given":"Arnau","family":"Bay\u00f3n","sequence":"additional","affiliation":[{"name":"Department of Hydraulic and Environmental Engineering Universitat Polit\u00e8cnica de Val\u00e8ncia  Valencia Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1289-2830","authenticated-orcid":false,"given":"Nigel","family":"Wright","sequence":"additional","affiliation":[{"name":"School of Engineering University of Birmingham  Birmingham UK"}]}],"member":"13","published-online":{"date-parts":[[2025,12,19]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"89","article-title":"Transformaciones recientes en el \u00c1rea Metropolitana de Val\u00e8ncia.
