Dam failure mechanisms and selection of modes and conditions of breaching.
Material type:
TextLanguage: ENG Publication details: 1986Description: 8p., 11 refs, 7 figsSubject: The paper describes through reference to some of SMEC's studies, the use of historic data on dam failures to select appropriate breach modes, and how these are accomodated in the dam break numerical model. Overtopping, piping and sudden collapse failures will be described, as appropriate to the dam under consideration, together with the natural flood events used. The presentation will be illustrated by study results showing discharge hydrographs, the attenuation associated with downstream channel conditions, and information on timing related to inundation levels which as a bearing on the formulation of plans for emergency relief operations
