This paper firstly described the dam break in the aspects of theories and models. Break parameters prediction, the understanding of dam break mechanics, peak outflow prediction were shown as the essential for the dam break analysis, and eventually determined the loss of the damages. Secondly, as an application example, Foster Joseph Sayers Dam break was further modeled and analyzed using USACE ...

hydraulic simulation of water flow in irrigation canals may reveal management shortcomings and help managers find solutions to them. hydraulic simulation models can be appropriate tools for understanding hydraulic behavior of irrigation systems. in the present study, the steady state hec-ras model was tested and compared with the mike 11 unsteady state model. a secondary irrigation canal in the...

flood routing in rivers is a mathematical procedure to determine flow hydrograph at a point in a river. one of routing methods is based on solution of saint-venant equations for unsteady flows. because this method is very complex and need to more information of river, other methods with simple calculations and reasonably accurate results have been extended and give generally satisfactory result...

Reliable estimates of river stream fl ow and fl ood zoning maps are needed for water resourcesmanagement such as fl ood mitigation, water supply, dam construction and irrigation. Flood zoning needsaccurate data and is one of the non-structural fl ood management methods. This paper describes theapplication of HEC-RAS and GIS model to determine fl oodplains maps for the part of Sardabrud Rivertha...
