Time-dependent reliability analysis of flood defences using gamma processes

Inclusion of time-dependent effects in flood risk analysis is useful to inform inspection and maintenance strategies. Several deterioration processes are incorporated in a reliability analysis of an earth embankment along the Thames Estuary based on multiple failure modes. Also, a biavariate gamma process model is developed to take correlated deterioration processes into account. That model is ...

Probability distribution of flood flows in Tunisia

L (Linear) moments are used in identifying regional flood frequency distributions for different zones Tunisia wide. 1134 site-years of annual maximum stream flow data from a total of 42 stations with an average record length of 27 years are considered. The country is divided into two homogeneous regions (northern and central/southern Tunisia) using a heterogeneity measure, based on the spread o...

Failure Probability and Remaining Life Assessment of Reheater Tubes

In this study, a real and significant industrial problem in a steam power plant was investigated. Reheater tubes in boilers are under the creep and the fireside corrosion mechanism that cause some of them to fail. Since the estimation of probability of failure (PoF) and remaining life (RL) is expensive and time consuming in the deterministic methods, in this work they were evaluated using struc...

Hybrid Regional Flood Analysis in the Namak Lake Watershed

Regional Flood Frequency Analysis (RFFA) is an efficient method in flood discharge estimation in ungauged watersheds or with short-term statistics. The purpose of the present study is to evaluate the hybrid method in RFFA and maximum flood discharge estimation in the Namak Lake watershed, Iran. For this purpose, 16 hydrometric stations were selected. The selected hydrometric stations were then ...
