Froude number is unity for critical flow, more for supercritical flow and less for subcritical flow.’<br /> <br /> The water depth at a critical flow is referred to as the critical depth.<br /> <br /> = Related articles on Designing Buildings Wiki =<br /> <br /> * Biodiversity offsetting.<br /> * Bund.<br /> * Catchment flood management plans.<br /> * Culvert.<br /> * Flood and water management act.<br /> * Flood risk management plans<br /> * Flood risk.<br /> * Pitt Review Lessons learned from the 2007 floods.<br /> * River engineering.<br /> * Scour.<br /> * SUDS Manual.<br /> * Sustainable Urban Drainage Systems.<br /> * Swales.<br /> * Water engineering.<br /> <br /> [[Category:Definitions]] [[Category:DCN_Definition]] [[Category:Water]] [[Category:Standards_/_measurements]] [[Category:DCN_Standard]]</div>
