Dam Break in Channels with 90° Bend
Publisher: American Society of Civil Engineers
Abstract: In practice, dam-break modeling is generally performed using a one-dimensional (1D) approach for its limited requirements in data and computation. However, for valleys with multiple sharp bends, such a 1D model may fail ...
One-Dimensional Model for Transient Flows Involving Bed-Load Sediment Transport and Changes in Flow Regimes
Publisher: American Society of Civil Engineers
Abstract: This study presents a novel, simple, but rather accurate approximation of the eigenvalues of the system formed by the Saint-Venant–Exner equations, based on the comparison between eigenvalues for the complete system and ...
Simplified versus Detailed Two-Dimensional Approaches to Transient Flow Modeling in Urban Areas
Publisher: American Society of Civil Engineers
Abstract: Simplified and detailed two-dimensional modeling approaches to transient flows in urban areas, based on finite-volume solution of the shallow water equations, are compared. Through the example of a dam-break flow in a ...
