Estimating Earthen Dam-Breach Parameters
Journal Title: Journal of River Engineering - Year 2013, Vol 1, Issue 2
Abstract
Dam failure leads to release of high volume of water which causes huge waves in downstream. Failure in dam may cause financial loss but life losses depend on the drowned zone, population residing in downstream of the danger zone and warning time. Therefore, it is inevitable to predict dam failure and its resulting dangers to reduce life and financial losses. Flood simulation models simulate flood caused by dam failure (such as DAMBRK and FLDWAV), the resulting outflow in dam failure and its route in downstream of the river. Such models mostly focused on outflow hydrographs. In these models, physical development of failure is not simulated but they describe dam failure process as parametric process which is defined as form of failure, final size and time required for developing it (destruction time). Therefore, dam failure parameters should be estimated for simulating dam failure and applied as input information in simulation model. For this reason, failure of Bidakan earth dam located in Chahar Mahal va Bakhtiari Province has been simulated by estimating parameters of failure, analyzing uncertainty of experimental methods for estimating parameters of failure and applying SMPDBK model.
