Levee Breach by Overtopping: The Effects of Soil Properties
<p>Levees are constructed for protecting infrastructure, croplands and cities from seasonal floods of low land rivers. Most levees are constructed from earthen materials. Also known as earthen embankments, these levees may fail by overtopping, when flood levels exceed design floods. Past studies …

Experimental and Numerical Modeling of Dam-Break and Levee-Breach Flows
… and numerical studies on dam-break and levee-breach flows. Experiments were conducted to gather comprehensive data on a steady levee-breach flow in an urban area and on unsteady 2-D and 3-D dam-break flows. Numerical studies of dam-break flows were carried out using Reynolds-averaged …

Mechanics of Sandbag Motion In Free-Surface Flow
… used for flood control and for the closure of levee breaches due to their low cost and ease of use. However, the available information for determining the appropriate size for a typical application and research on the mechanics of motion of sandbag needed to optimize their placement are …

Landscape vulnerability to flood impacts in a human-dominated floodplain
… Floodway in May 2011. The historic pre-conceived levee breach and subsequent inundation of the agricultural floodplain represents a large-scale experiment to assess vulnerability of intensively managed landscapes to extreme events. Pre-flood and post-flood high-resolution Lidar topography datasets …

Effetti dell'attività della fauna sulla stabilità degli argini: Valutazione Ecoidraulica dei meccanismi di rottura arginale e tecniche di ripristino
… types of river structures to control the flow. Levees (also known as dikes), for instance, are simply man-made embankments built to keep a river from overflowing its banks. However, river flooding is a natural phenomenon so that it is not rare that rivers overflow their banks and flood the …

Experimental Investigation of Steady Flows at a Breached Levee
<p>Steady flow at a breached levee is studied in this dissertation through a generalized model and a case study. The generalized experimental set-up consists of a main channel with an opening in its side wall and an adjustable sluice gate at its downstream end. Water surface elevation and the …
