Developing Guidelines for Two-Dimensional Model Review and Acceptance [PDF]
, 2018 Two independent modelers ran two hydraulic models, SRH-2D and HEC-RAS 2D. The models were applied to the Lakina River (MP 44 McCarthy Road) and to Quartz Creek (MP 0.7 Quartz Creek Road), which approximately represent straight and bend flow conditions ...

Flood risk assessment in an urban area: Vila Nova de Gaia [PDF]
, 2013 This paper proposes a methodology for flood risk assessment in a non fluvial urban flood. Two hazard classifications were considered; one with water depth and flow velocity classes and other with the product of water depth and flow velocity.

Ice-Cover and Jamming Effects on Inline Structures and Upstream Water Levels
, 2017 River ice cover is a reoccurring phenomenon in the Northern United States every year. Sheets and layers of ice result in a rise of water surface elevation and may lead to ice jams in a river.
