Accurate prediction of levee breach flow is crucial to the mitigation of floods, and for timely breach closure. In this work, flow in an idealized levee breach has been studied for the case of a trapezoidal embankment. Flow data including water depths, surface velocities, and flow discharges were obtained from 28 experiments considering different c...
Article
Laboratory experiments were conducted to investigate the reduction of flood depth in a channel due to an engineered levee breach. Different combinations of inflow hydrographs, breach openings, and floodplain storage areas were considered. Inflow hydrographs with various peak discharges, hydrograph shapes, and flood durations were generated by a com...
Article
In this research a laboratory study was carried out to investigate the scour phenomenon in sandy soil beds downstream different shapes of culverts, Four shapes of culverts such as circular, ellipse, rectangular and square were used. So, a best hydraulic section was used in rectangular and ellipse shapes. The study includes the measurement and compa...
Conference Paper
In recent decades, frequent floods of historic magnitude have been causing extensive damages to infrastructure, loss of property, and fatalities around the world. Levees are constructed along rivers to prevent inundation of croplands and urban areas. The total length of levee systems in the USA is over 100,000 miles. Levee failure can cause catastr...
Conference Paper
Extreme flooding has become more prevalent due to climate change and has been causing extensive damage, loss of property, and fatalities around the world. Levees are often constructed to prevent inundation in floodplains and urban areas. Flood mitigation efforts during extreme floods include forcing a breach in the levee at a strategic location to...
Conference Paper
Experiments on steady levee-breach floods was conducted in the Hydraulics Laboratory, the University of South Carolina. An idealized levee with different breach width (0.4 m, 0.5 m, 0.6 m, and 0.7 m) and downstream weir height (0.08 m, 0.10 m, 0.12 m, and 0.14 m) and a constant flow rate of 75 l/s was considered. Water depths along various transect...

In this research the hydraulic characteristic of seventy seven cross sections along 21 km of Tigris River at Mosul city were studied. These cross sections were surveyed and their bed and water surface elevations were measured. The river at the studied reach have a different morphology and include three different shapes (meander part braided part an...

Abstract: weirs are the most commonly used device in channels for flow measurement and flow regulation due to its simplicity. Conventional rectangular, triangular and trapezoidal weirs are among the most common oldest types of weirs, progress ogee crest weir and cylindrical weirs are started to use in hydraulic engineering. The advantages of the ci...

In this research a laboratory study was carried out to investigate the scour phenomenon downstream gabions protecting rockfill weirs. The study includes the measurement of maximum scour depth and length of scour hole downstream the weir. The shape of scour hole was also studied. Three sizes of aggregate of diameters (0.7937, 1.111, 1.5875)cm were u...
Article
In this research, the phenomenon of scour downstream triangular plan form weirs on stone beds were studied experiment ally. The study deals with the measurement of maximum scour depth and the length of scour hole downstream the weir. The shape of scour hole was also studied. One hundred and eight runs were conductedin a laboratory channel. Three si...
