Reliability analysis of Reno mattress for canals

In the present work, we develop a probabilistic approach to analyze the failure functions related to the overall stability of a Reno mattress of an open canal. The considered state functions are those related to critical velocity, stability of the channel bottom, deformation effects, traction forces and residual velocity at the underside of the revetment. To take the uncertainties into account, the water flow rate is considered as random variable, generated by Poisson law. For the need of reliability analysis, Monte Carlo simulation method is used. Also, the Matlab© software is used for generating random draws. The developed method in this work is applied to a practical example which is taken from the engineering field.
