Abstract: A two-dimensional numerical model is developed to predict the time variation of bed deformation in alluvial channel bends. In this model, the depth-averaged unsteady water flow equations along with the sediment continuity ...

Abstract: Contrary to general statements in the literature, the investigations reported in this paper show that semicoupled models are not necessarily unstable and give results comparable to those of coupled models. For this purpose, ...

Abstract: A new technique is presented utilizing the frequency response for the detection of partial blockages in a pipeline. In the system frequency response, a partial blockage increases the amplitude of the pressure oscillations ...

Abstract: On August 29, 2005 Hurricane Katrina resulted in several breaches in the levees and flood walls protecting New Orleans. Of the 20 breaches, the 17th Street Canal breach caused much of the city flooding. In this paper, the ...
